A material certificate, a dimensional report and ISO certification answer different questions. Specify the documents needed for your order before quoting so the scope of evidence matches the part requirements.
For a sourcing review, contact Extramet Products with the scope of material supply, finishing and inspection you need.
Do not use one document as a substitute for another
| Document | Typical purpose | Scope to confirm |
|---|---|---|
| Certificate of conformity | Statement that the supplied order meets identified requirements | Referenced order, specification, exceptions and issuer |
| Material test or lot record | Identifies material and any reported test results | Grade, lot, properties, methods and actual included data |
| Dimensional inspection report | Records inspection against the drawing | Revision, features, measured values and sampling |
| ISO management-system certificate | Identifies a certified management system and scope | Legal entity, sites, scope, issuer and validity |
ISO certification is not an individual part inspection report and does not by itself certify suitability for a medical or aerospace application. A material document may contain identification only, or include test data; request the specific content needed rather than relying on the word certificate.
Example report fields to agree on
For a pin, a requested dimensional report might identify drawing revision, lot, inspection date, measured OD and the agreed finish check. The exact features, sample quantity and method must be accepted for the order. This is an example of fields, not a redacted Extramet report.
When identification must stay on the component, discuss laser marking for part and lot identification alongside the documentation requirements.
Check Extramet’s current ISO certificate and ask for the current certificate and order-specific document scope. Keep the accepted requirements with the purchase order; do not assume every optional report is included.
Why documentation matters
Carbide components often live inside high-value tooling, production equipment, and regulated supply chains. Documentation gives buyers evidence that material, dimensions, and processes match the purchase requirements.
Do not wait until shipment
If a buyer needs certs, inspection reports, or customer-specific QA paperwork, those needs should be listed on the RFQ and purchase order. Late documentation requests can delay shipment.
Inspection and technical review
For tight-tolerance carbide parts, inspection planning is part of manufacturability. Define datums, critical dimensions, surface finish, and reporting format early.
Frequently Asked Questions
Is ISO certification the same as a part inspection report?
No. ISO relates to the quality management system. Inspection reports document measured part dimensions or characteristics.
Should cert requirements be on the PO?
Yes. Put documentation requirements on the RFQ and purchase order.
Can documentation affect price?
It can, because reporting, inspection, and traceability add process time.
The complete carbide RFQ checklist brings the drawing, material, inspection and delivery requirements together.
The near-net versus finish-ground comparison explains who should own the remaining operations and final acceptance.
Send the drawing, application and quantity through the RFQ form when the requirements are ready for review.
