What a 12-Inch Flat Compliance Certification Covers

A step-by-step guide to the 12 inch flat compliance certification process, from checking your flat's catalog value to filing the Zygo CERT-12 document correctly.
Quick answer
A 12-inch flat compliance certification confirms that your flat meets the catalog value Zygo publishes for that size and grade. Order the standard CERT-12 option for a 12" flat, then file the certificate with the flat's records so the compliance claim stays traceable.
Compliance, not calibration: what the document actually states
Compliance certification is a statement that the flat performs to the catalog value, not a fresh calibration report with new measured data. If you need updated measurement values rather than a confirmation against the published specification, a calibration service is the right request and this certificate will not replace it.
This distinction matters most when a customer or auditor asks for evidence. Compliance documentation answers 'does it meet the published value?' while calibration answers 'what does it measure now?' Decide which question you need to answer before you order.
When a 12-inch flat needs this certificate
Order the certification when a 12" flat is moving into incoming inspection, being transferred between departments, or being supplied to a customer who requires documented compliance. It is also useful when you want a single, consistent reference document on file for a flat already in service.
Skip it if your flat is already covered by a valid certificate for the same catalog value, or if the receiving party specifically requires calibration data. In those cases the certificate adds paperwork without answering the actual requirement.
Steps to complete the 12-inch flat compliance certification
- Confirm the flat's catalog value: Identify the catalog value published for your 12" flat before ordering. The certificate verifies compliance to that value, so the value must be known and current. Common mistake: assuming any 12" flat qualifies without checking its catalog value first.
- Order the CERT-12 option: Select the Compliance Certification 12" Flat, standard option SKU CERT-12, and reference your flat's identifying details in the order. Checkpoint: confirm the SKU on the order matches CERT-12, not a different size or service.
- Match the certificate to the flat: When the certificate arrives, verify that the flat size and catalog value on the document match the flat it will accompany. Common mistake: filing a certificate against the wrong flat when several 12" flats are in service.
- File and reference the certificate: Store the certificate with the flat's inspection records and note its location in your quality system so it can be retrieved during audits or customer requests. Checkpoint: a certificate that cannot be located on request provides no compliance evidence.
