Disclaimer
Read this before relying on anything published here.
SpecPedia is an independent publisher. It is not a standards development organisation, a notified body, a certification body or a law firm.
Not the authoritative text
Our articles summarise and explain requirements that originate in documents published by others. They are not a substitute for the official standard, regulation or directive. Where our text and the official text differ, the official text governs.
If you are making a compliance, certification, procurement or safety decision, obtain the licensed standard from the issuing body and, where appropriate, take qualified advice.
No affiliation or endorsement
References to ISO, IEC, ASTM, CEN, ANSI, EUR-Lex, NIST or any other organisation are descriptive only. Nothing on this site implies affiliation with, endorsement by, or authorisation from those organisations. Organisation names and standard designations remain the property of their owners.
Sourcing limits
We deliberately restrict ourselves to material that can be lawfully redistributed: public-domain texts, CC BY licensed material, government open data, legislation, and official abstracts. Where only an abstract is publicly available, we describe and interpret it, cite it, and link to the publisher.
Standards change. We time-stamp every article and review the library on a rolling schedule, but there will always be a gap between an amendment being issued and our page being updated. Verify the current edition before relying on a statement.
External links and translations
Links to third-party sites are provided for verification. We do not control those sites and are not responsible for their content or availability.
Non-English versions are written by native-language editors rather than machine-translated. Even so, only the English version should be treated as the reference edition for a dispute about wording.
Limitation of liability
To the maximum extent permitted by law, we accept no liability for loss or damage arising from reliance on the content of this site. Use of the material is at your own risk.
