Notes
- This index has been prepared by Emsal to show what each standard is for; titles are summaries, not official titles. For the full text and current edition of a standard, refer to the publishing body or your national standards body.
- In Türkiye, European standards are published with the same number and the TS EN prefix (e.g. EN 12266-1 → TS EN 12266-1).
- The EN ISO label indicates that the ISO standard has been adopted unchanged in Europe; the content is identical.
- Edition years are given only for ISO and EN entries verified against the official catalogue. API, ASME, MSS and ASTM standards are updated frequently; confirm the current edition with the publisher for orders and design.
- Withdrawn DIN and BS standards are listed with their current replacements because they are still referred to in the field. Chinese (GB), Russian (GOST) and French (NF) national standards are not covered.
- Accuracy and currency are not guaranteed; use the current edition of the standard for design and purchasing decisions. How the library is compiled →
