A robot IP rating is not a hygiene plan
How to specify the hygiene zone, configured robotic cell, cleaning regime and component-level evidence needed for a food or packaging application.
Record the interval from cleaning to use — method added 12 October 2026
A cleaning completion timestamp answers when a task ended. It does not describe what happened to the product-facing surfaces before production resumed. For a robot cell left idle overnight, ask a separate question: which evidence connects that completed cleaning task to the actual condition and intended use at the next run? Keep the cleaning result, subsequent events and qualified pre-use decision as separate records.
FSANZ's cleaning and sanitising guidance distinguishes removal of dirt and food waste from destruction of microorganisms. Its processing-food-safely page says food-contact surfaces should be cleaned and sanitised before use and food protected from contamination. Both pages were updated 30 September 2025 and checked 12 October 2026. These are general food-business instructions, not robot-specific methods, a validated hold-time rule or permission to apply their example chemicals to an installed cell.
Start the interval record with the exact installed configuration, affected surfaces, procedure revision, completion time and cleaning evidence reference. Then describe how those surfaces were protected, where removed tooling was stored and which relevant conditions were observed. A cover's presence is an observation; it is not proof that the protection was effective. Where the record is missing, leave the gap visible rather than inventing an uneventful interval.
Log relevant access and interventions between completion and use: maintenance, adjustment, tool handling, cover removal or another event identified by the site's hazard assessment. Record none only when that statement has a documented basis. Link each event to its time, affected boundary and evidence. An intervention does not automatically establish contamination, but an earlier cleaning record cannot by itself resolve the consequences of a later change.
Define the next intended product, process and start time, then link the site's required pre-use check to its method, result, date and reviewer. Qualified food-safety and engineering owners decide what verification is appropriate and what restrictions apply. This worksheet does not prescribe sampling limits, repeat-cleaning criteria or a maximum idle period. A visual observation must not be presented as proof for hazards it was not designed to assess.
Consider a hypothetical cleaned gripper stored under a cover, then handled during a cable repair before the next batch. The completion record still describes the earlier task. Add the repair and handling record, identify the surfaces affected and preserve the outstanding question for the responsible owner. Do not erase the original result, silently carry it forward or label the whole cell failed merely because an intervention occurred.
The linked hygiene tool now includes an independent clean-to-use interval worksheet. It flags seven missing evidence fields and exports the recorded context, intervening events, next-use check and qualified review. Filling the component or instruction-change register cannot complete this separate record. Even a fully assembled worksheet is only material for a site decision: it grants no food-contact qualification, hygiene validation or restart permission.
Trace the part that was installed — method added 7 October 2026
A replacement order identifies what was bought. It does not establish what is now fitted at a product-facing interface. After maintenance, connect the removed component to the exact installed part, revision and lot where available, its location and the dated work record. Keep an unknown identifier visible instead of treating a similar shape, colour or supplier description as proof of equivalence.
3-A's public update of 13 February 2026, checked 7 October, discusses replacement procedures and access to surfaces behind removed gaskets. That is a reason to ask what the maintenance record covers, not evidence that a particular replacement is suitable. The full paid standard was not reviewed. Record the supplied assembly, relevant procedure and inspection evidence, then let qualified owners determine the applicable requirements.
Keep material evidence attached to its stated use. FSANZ's food-packaging guidance, updated 30 September 2025 and checked 7 October 2026, identifies food type, contact, storage conditions and reuse cleaning as factors in packaging suitability. This is packaging guidance, not a qualification procedure for robot seals or grippers. The transferable question is whether the assurance being offered actually addresses the proposed exposure; the site's owners must resolve the component-specific answer.
Our proposed trace record separates identity, installation and evidence scope. Identify the product-facing location and contact role, removed identifier, installed identifier, work-record date and configuration revision. Link the relevant material statement and its limits to the actual product and cleaning conditions. If a statement names a different part, revision or use, record the mismatch and request clarification rather than silently carrying the earlier conclusion forward.
Consider a hypothetical gripper seal replaced with a visually similar spare. A packing slip and a general material certificate do not establish which lot was installed or whether the statement covers that spare and its intended exposure. Preserve the old evidence as history; link the new installation record and unresolved scope question to a named owner. Missing traceability is a reason for review, not a basis for declaring either safety or failure.
The local hygiene register now checks the replacement trace independently of its cleaning-exception and instruction-impact records. Filling those earlier records cannot hide a missing installed identifier or work record. Its download retains the trace, reviewer and restrictions. Even when no gaps remain in the form, RobotAtom has not approved food contact, validated cleaning, certified compliance or authorised restart. A qualified site decision remains separate from assembling the evidence.
Close a cleaning exception before the next run — method added 5 October 2026
A failed inspection, missing cleaning record or unexplained residue should remain visible until the responsible site team has reviewed the correction and repeat-check evidence. Removing an item from a task list is not evidence that the affected surface is ready for the next production run. Record the installed configuration, exact surface or interface, product and cleaning conditions, observed exception and immediate restriction before changing anything.
FSANZ's cleaning and sanitising guidance, updated 30 September 2025 and checked 5 October 2026, distinguishes removing dirt and food waste from destroying microorganisms and says cleaning comes before sanitising. Its general food-business examples are not cleaning instructions for a robot. The robot, end effector, sensor, coating and seal may have different permitted exposures. Use configuration-specific manufacturer instructions and a site-approved procedure; do not transfer a generic temperature or chemical concentration into an unverified cell.
For each exception, name the corrective action and its owner. Describe what was cleaned, replaced, adjusted or inspected, with the dated work record and relevant instruction revision. If a gasket is removed or replaced, ask which previously hidden surfaces need inspection and how the replacement was verified. 3-A's 13 February 2026 public summary of General Requirements 00-02 discusses replacement procedures and cleanable, inspectable surfaces behind removed gaskets. The full paid standard was not reviewed, and this summary does not verify a particular robot installation.
Define the repeat check before interpreting its result. Identify the affected area, conditions, method, site-defined acceptance criteria, sampling or inspection plan where applicable, actual result, date and evidence reference. The qualified food-safety owner chooses methods appropriate to the hazard and process. This guide does not set a universal swab limit or make a visual check sufficient for every hazard. Keep an inconclusive result, missing evidence or result outside the agreed criteria open; do not substitute a supplier certificate for a site cleaning outcome.
Our proposed closure record separates the correction, retest and review decision. In a hypothetical case, a cable cover is replaced after residue is found beneath it. The replacement invoice records an action, but it does not establish whether the exposed area was cleaned effectively or whether the new arrangement can be inspected. Keep the exception withheld until the required repeat-check evidence and responsible review are recorded. If the owner accepts a restricted disposition, preserve the restriction and its boundary instead of labelling the whole cell passed.
3-A's public update separates processor validation from manufacturer seal-integrity verification. That distinction helps allocate evidence ownership; it is not a universal allocation of legal duties for every jurisdiction. The linked register stores a local exception, correction, dated retest reference and reviewer disposition. Even a fully assembled record remains evidence for qualified review, not food-safety certification, machinery-safety approval or permission to restart. Reopen affected evidence after changes to the product, cleaning method, exposed parts or installed geometry.
Review the instruction change before carrying evidence forward
Instruction-change method added 6 October 2026. A cleaning record belongs to a particular procedure and installed configuration. When an instruction changes, preserve that record with its old revision. First ask which assumptions changed: chemical, concentration, contact time, temperature, pressure, rinsing, drying, disassembly, access or robot pose. The previous result may still describe what happened, while no longer supporting the next cleaning regime.
The distinction matters when general guidance and equipment instructions appear to disagree. FSANZ's food-business guidance, last updated 30 September 2025 and checked 6 October 2026, distinguishes cleaning from sanitising and tells businesses to follow commercial sanitiser instructions. It is not a robot cleaning procedure. Universal Robots' SW5_26 cleaning page, checked the same day with no publication date displayed, describes wiping and excludes bleach, including diluted bleach. This manufacturer example does not establish compatibility for another model, end effector or installed cell.
Record the old and new instruction references side by side, including their revision identifiers and the parts each covers. A new document date is not enough: identify the changed requirement and the evidence that relied on it. If the instruction changes a permitted spray area, revisit exposed interfaces and nearby sensors. If disassembly changes, revisit which surfaces can be reached and inspected. If the cleaning pose changes, check the resulting access and drainage assumptions rather than treating it as a software-only edit.
Map the change to named evidence records, owners and unresolved questions. Keep a material-compatibility statement separate from a site cleaning outcome. Ask the manufacturer to resolve an instruction mismatch for the exact supplied configuration, and ask the qualified site team which verification needs repeating. RobotAtom proposes this traceability method; it does not prescribe a universal retest threshold or determine whether a changed procedure is safe.
In a hypothetical case, a site adds a sanitiser to a procedure previously verified with a different agent. The earlier inspection remains evidence for the old procedure. It cannot establish that the new agent is compatible with the gripper seals or that the revised cleaning process controls the site's hazards. Mark the affected records for review, retain the restriction and obtain the required compatibility and site-verification evidence before the responsible owner decides what can proceed.
The linked hygiene register now captures previous and current instruction revisions, changed limits and affected evidence, and a dated owner review with restrictions. Its open-gap summary prevents a filled-in component list from hiding an unfinished instruction-impact review. Completing these entries assembles a record for qualified review; it does not validate cleaning, certify food safety or authorise restart. The download retains both the original evidence boundary and the change record.
Ingress protection answers a narrower question
An IP rating is evidence about an enclosure under a defined classification. It is not by itself evidence that a robot is hygienically designed, compatible with a site's cleaning chemicals, suitable for food contact or cleanable as part of the configured application.
IEC 60529 classifies degrees of protection provided by enclosures for electrical equipment. Its public scope does not establish a complete hygiene or sanitation programme. A useful requirement must therefore keep ingress protection as one field inside a broader hygiene case rather than treating the highest-looking IP code as a pass.
Define the hygiene case before selecting the robot
ISO 14159:2002 remains the published international standard for machinery hygiene requirements but is marked for revision and expected to be replaced. Its public abstract applies to machines and associated equipment where consumer hygiene risks can occur. The applicable edition and detailed requirements should be confirmed by the customer's food-safety, hygiene and engineering owners.
- Identify the product, process and hygiene zone, including whether exposed product or product-contact surfaces are nearby.
- State whether the robot or configured parts can contact product directly, contact it indirectly or remain outside the product zone.
- Describe the soil, residue, allergen and contamination risks that the cleaning process must remove or control.
- Name the wet-cleaned or dry-cleaned regime, required inspection and verification, and the site owner who approves them.
- Record the applicable jurisdiction, customer rules and sector standards instead of assuming that a general robot rating answers them.
Assess the complete configured system
EHEDG released Guideline 62 Part 1 in March 2026 for fundamental hygienic-design criteria for robots in open food-processing environments, covering wet- and dry-cleaned conditions. EHEDG says it addresses construction, installation, integration and documentation across the lifecycle.
EHEDG also says later parts will address end effectors, system integration, mobile robots and other applications. That boundary matters: evidence for a robot body cannot automatically be carried across the gripper, adapters, dress pack, connectors, covers, base, fasteners, controller, nearby guarding, conveyors or drainage arrangement.
- List the exact robot variant and the protection rating for each relevant area rather than one rating for the product family.
- Include every exposed tool, sensor, cable, connector, cover, seal and mounting interface in the hygiene review.
- Identify gaps, ledges, hollow sections, fasteners, damaged coatings, trapped liquid and inaccessible surfaces that may affect cleaning or inspection.
- Define how utilities enter the hygienic zone and where runoff, residue and condensation can go.
Turn washdown into a bounded cleaning regime
ABB currently describes its IRB 1200 Hygienic body as IP67 and its axis-six flange as IP69K with a stated maximum of 30 bar. ABB separately describes wipe-down cleaning with a specified detergent and washdown cleaning using a protection cover and a defined regime. These are manufacturer instructions and ratings for the named configuration; they illustrate why pressure, robot area, cover and cleaning method must be recorded separately, not independently verified proof that a proposed cell meets a customer's hygiene requirement.
- Name each detergent and sanitiser, concentration, contact time and material-compatibility evidence.
- Set water temperature, pressure, nozzle type, spray distance, angle, duration and areas that must not be sprayed.
- State cleaning frequency, disassembly, rinsing, drying, inspection and pre-operation release steps.
- Define who cleans, who verifies, what result passes and how deviations or damaged seals and coatings are handled.
- Keep the manufacturer's current cleaning instructions with the exact robot and accessory configuration used at the site.
Keep different evidence types separate
ISO 21469:2006 covers hygiene requirements for lubricants that can have incidental product contact and is under review in 2026. Its public scope excludes substances used as product additives or in direct product contact and does not address occupational health and safety. That narrow scope is another reason to preserve each claim with its own boundary.
- Ingress protection: the rated enclosure area, test classification and any installation conditions.
- Hygienic design: surface, geometry, joints, drainage, accessibility, materials and documentation for the intended use.
- Cleaning compatibility: the exact chemical, concentration, temperature, pressure, exposure time and maintenance limits.
- Food-contact evidence: the exact material, surface or component, contact type, region and applicable rule.
- Lubricant evidence: product, use point and whether contact is incidental; do not turn a food-grade lubricant claim into a cleanability claim.
Make hygiene acceptance observable
Before production use, inspect the exact installed system against the approved drawings, component list and cleaning instructions. Run representative production and cleaning cycles, record access problems, trapped residue or liquid, coating and seal condition, disassembly effort, inspection findings and the agreed hygiene-verification results. The responsible site team should define the method and threshold appropriate to its product and process.
Reopen the assessment after a material change to the product, soil, allergen, cleaning chemical or method, robot or tool, cable routing, cover, seal, coating, lubricant, mounting, drainage, software-controlled cleaning pose or maintenance practice. Preserve the previous result as evidence for the old configuration rather than carrying its pass forward.
Ask what a certificate actually covers
A certificate belongs to a named model, configuration, scope and edition. Ask for its number, current status, covered parts and cleaning conditions; then check whether the offered end effector, tool changer, dressing and installation match. A component mark must not be presented as proof that the whole installed system qualifies.
3-A Sanitary Standards' public guidance describes Standard 103-00 for robot-based automation systems in food processing. Its 2021 coordination bulletin distinguishes component qualification for end-of-arm tooling and tool changers from 3-A Symbol eligibility for a complete system. Neither route verifies the processor's cleaning outcome at this site. Check a claimed authorisation against 3-A's current certificate listing and ask the site food-safety owner to resolve any mismatch.
Treat packaging contact as its own route
A robot handling sealed cartons and a robot touching primary packaging do not present the same contact boundary. Map where packaging is open, gripped, presented or inserted, and ask how the operation prevents damaged or contaminated packaging reaching food. In Australia, FSANZ explains that Standard 3.2.2 clause 9 requires packaging to be fit for intended use, unlikely to contaminate food, and handled so the packaging process does not contaminate it. Do not carry that Australian legal summary into another jurisdiction without checking the local rule.
For an evidence review, hold an exposed component open when its dated material or cleanability record is missing, a certificate does not cover the offered configuration, the manufacturer's cleaning limits conflict with the site's regime, or representative cleaning verification has not passed. This is a buyer's cautious hold rule inferred from the cited hygiene guidance, not a threshold prescribed by any one standard. Record the gap and owner; do not replace an installed-cell test with a brochure claim.
Record claims without turning them into certification
IEC, ISO and EHEDG are authoritative for the published scopes and status cited here, but their public pages do not verify a named installation. ABB is authoritative for its own documented product claims and instructions; those claims are not independent verification of a customer's configured robotic system.
RobotAtom records the hygiene zone, cleaning regime, component-level evidence, source date, owner, unknowns and required validation. It does not certify hygienic design, food safety, ingress protection, cleaning effectiveness, robot safety or regulatory compliance. Qualified hygiene, food-safety, engineering and safety owners must assess the actual application under the applicable requirements.
