Why requirements differ from one sector to another
Two parts that are identical on the drawing can require months of qualification or a simple order confirmation, depending on where they will be fitted. It all comes down to risk: a failure on an aircraft engine, an implant or a pressure vessel does not have the same consequences as a defect on a shelving bracket. Each industry has therefore built its own framework: sector-specific quality standards (EN 9100 for aerospace, IATF 16949 for automotive, ISO 13485 for medical), traceability, inspection and documentation requirements, and sometimes European regulations that directly bind the manufacturer.
These requirements are passed down the chain: the final buyer imposes them on its suppliers, who pass them on to their own subcontractors. For a buyer and a workshop alike, knowing what applies to the part from the quote request avoids unpleasant surprises: expected certifications, material certificates, first article report, qualification lead times. Always ask the supplier for their current certificates and check that they cover the process concerned.
The pages for each sector detail these points, without replacing your customer’s specifications: these take precedence. To structure your requirements, use our specifications guide.
