| Classification themes | Availability classes, protection classes, and resource-performance concepts | Availability, security, and energy-efficiency classification concepts |
| Edition status | Check each EN part and national adoption | Check each ISO/IEC part; publication status can differ by part |
| Project use | Often selected for European or nationally adopted requirements | Often selected for an international procurement or multi-country basis |
01
Specify each part
A contract should identify each applicable part and edition rather than cite only the series name.
02
Check national adoption
EN editions differ by part, and national adoptions can add a prefix or adoption date. Local code obligations still require verification.
03
Selection and conformity
Selection should follow jurisdiction, owner risk, customer and procurement requirements, portfolio basis, and intended assessment. Conformity to one series does not automatically prove conformity to the other.
