Knowledge centerStandards
What each standard is for, what it requires in broad terms, where it is used and what auditors and inspectors typically find. Written by engineers, for engineers and buyers.
QUALITAS TR inspects and audits against these standards on behalf of buyers and helps suppliers close gaps. We are not a certification body and do not issue certificates. Where certification or a notified body is required, we explain who can provide it.
Summaries are written independently and do not reproduce the standards. Always refer to the current official edition from the publisher.
