The requirements are currently explicitly detailed in IEC 60079 Part 14 Annex A, detailing knowledge/skills and competency requirements for responsible persons, operatives and designers.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as global certification scheme for electrical and mechanical craftspersons and designers. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 20, 2025. The linked authority identifier is Q16820683. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2021 and 2017.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
