Lancing Ltd · Published · General selection guidance; final suitability requires application review.
Start with the contact boundary and intended use
Trace the food from the source connection to the nozzle outlet, including the return circuit where one exists. List the components that contact it and those whose substances could reasonably transfer to it. Separately identify bottle and closure documentation supplied by the packaging manufacturer. This avoids a file that proves the tank material but says nothing about a replacement hose or hidden valve seal.
The Food Standards Agency’s food-contact materials guidance explains the regulatory purpose: controlling transfer of substances from materials to food. Requirements and supporting evidence depend on the material, intended use and destination market. Have the responsible compliance specialist confirm the applicable rules for Great Britain, Northern Ireland or export; this checklist is not a certificate or legal determination.
Use a component-to-evidence register
| Component group | Information to request | Check against the project |
|---|---|---|
| Metal contact parts | Material grade and component identification; supporting material records where required | The actual tank, cylinder, valve, manifold and nozzle scope |
| Flexible hoses and tubing | Material or compound reference, supplier and intended-use limitations | Food type, contact conditions, cleaning chemicals and replacement route |
| Seals, gaskets and valve seats | Compound or grade reference and evidence appropriate to the material | The installed parts rather than a similar compound name |
| Plastic contact parts | Applicable declaration of compliance and supporting assessment or testing | Food types, contact duration, temperature and repeated-use conditions |
| Cleaning and lubricants | Cleaning instructions and details of any potential incidental-contact lubricant | Approved use, application point and maintenance controls |
| Replacement parts | Part number, material reference and documentation revision | How an equivalent replacement will be identified and approved |
Treat this as a document request list, not a claim that every item requires the same statutory certificate. A declaration should identify what it covers and its conditions of use; a laboratory report should identify the sample and basis of the assessment. Ask the supplier to explain the relationship between evidence and the delivered assembly.
Do not confuse material suitability with cleanability
A documented material can still be used in a product path that is difficult to drain, inspect or clean for your application. Review access, retained product, joints, removable parts and the cleaning boundary separately. Conversely, a visually clean test does not demonstrate chemical suitability of the contact materials.
For a bottle filler, ask how valves, piston seals, hose connections and nozzle shut-off parts are exposed to the intended cleaning method. Where clean-in-place is proposed, define the circuit and the evidence needed to show that cleaning reaches the relevant surfaces. Avoid treating the ability to circulate liquid as cleaning validation. The cleaning and changeover guide covers that production decision.
Write the use conditions into the purchasing brief
- Foods and ingredients, including formulation characteristics relevant to compatibility.
- Maximum intended product-contact temperature and duration, including waiting and recirculation.
- Normal batch sequence and any allergen or flavour changeover constraints.
- Cleaning products, concentrations and conditions as defined by the site procedure.
- Expected repeated-use pattern and parts intended for routine replacement.
- Required documentation language, part identifiers, revision control and review responsibility.
Do not rely on a food-contact logo to describe these conditions. A supplier can only assess a meaningful request when the exposure is defined. Use the machine specification checklist to tie the documentation request to the same product and operating window used for the quotation.
Close the evidence gaps before production release
Give each requested item an owner, status and reference. Record whether the evidence matches the delivered component, whether its use conditions cover the project and which issue remains unresolved. At handover, compare the final parts list with the approved schedule rather than filing the original quotation as though no components changed.
When seals or hoses are replaced, retain the approved reference and record any substitution. A change in material, recipe or cleaning regime may require another review. Separately, the food business needs its own food-safety management procedures and records; equipment documentation does not replace those responsibilities.
Where this guidance stops
This page helps a buyer organise questions and evidence. It does not declare a particular Lancing machine compliant with an unspecified food-contact standard, promise that every document is included as standard or prescribe a migration-test programme. Confirm the required evidence, assessments and responsibilities in the project scope before ordering.
