Food machinery customers expect a document pack per machine: material certificates for product contact steel, weld records, surface finish checks, gasket and lubricant declarations, and cleaning validation results. Link each document to the serial number as the work happens, so the pack is ready at handover.
What the customer’s quality team looks for
A food plant’s quality manager reviews the machine as a hazard source. The questions are plain. What touches the product? What is it made of? Can it be cleaned without taking it apart for hours?
The handover pack answers those questions on paper. A missing certificate delays acceptance, and sometimes the payment tied to it.
Ask for the customer’s document checklist at order stage. Many send one.
Material certificates for product contact parts
Every stainless sheet, tube and bar in the product zone needs a mill test certificate that traces to a heat number. Stamp or record that number when the material is received and again when parts are cut.
Losing the link between heat number and part is the common failure. A plate is nested, cut into five parts and the offcut is reused. Unless the number is transferred, the certificate proves nothing.
Keep gasket, seal and elastomer declarations alongside. Customers ask for food-contact compliance statements on those too.
- Mill test certificate with heat number
- Material grade on the drawing
- Heat number marked on cut parts
- Food-contact declarations for seals and gaskets
Weld records and surface finish
In a hygienic design, product zone welds should be continuous, ground smooth and free of crevices. Record who welded each joint, which procedure was used, and who inspected it. Photos of internal welds help, especially on tanks and pipework.
Surface roughness is checked with a profilometer on contact surfaces. Write the readings against the part number.
Passivation or pickling records belong here too. They show the stainless layer was restored after welding.
- Welder ID and weld procedure reference
- Inspection result and date
- Roughness reading on contact surfaces
- Passivation batch and date
Cleaning validation and lubricant files
Customers will ask how the machine is cleaned and how you know it works. Keep the cleaning procedure, the drain and dead-leg checks, and any swab or rinse test results from your trial run.
If the machine uses grease in a zone near product, record the lubricant name and its food-grade certificate. Mixed greases cause problems later.
Many customers also request an EHEDG or similar design review. Hold those correspondence files with the machine.
Build the pack as you build the machine
Assembling certificates in the last week before shipping is a scramble. People have left, files are missing and heat numbers are guesswork.
Make document capture a step in each job card. The store attaches the certificate on receipt, the welder logs the joint, and quality adds the test results. At handover, the pack is exported by serial number.
Take your last shipped machine and try to build its pack today. The gaps you find are the steps to add to your job cards.
Hygienic machine document pack index
A one-page index with a row per document type: material certificates, weld log, roughness readings, passivation record, seal declarations, lubricant certificate, cleaning procedure and validation results. Columns show the owner, the stage when it is captured, the file location and a tick for received.

Do all parts need material certificates?
Product contact parts do. Frames and guards often need less. Confirm the split with the customer in the order stage.
Who should own the document pack?
Quality or the project manager. Each department adds its own record, and one person checks the pack before shipping.
How long do we keep these records?
Keep them for the contract term or the customer’s stated retention period, whichever runs longer. Ask what period applies and write it into the order.
What if a certificate is missing at handover?
Tell the customer early, trace the heat number with the supplier and offer a verified test of the material if the supplier cannot supply a certificate.
