Revisions

They can be understood as three types.

Erratum (Mistake)
Corrigendum (Correction)
Emendatio (Amendment)

IEEE Standards Association Standards Board Operation Manual, defines the differences between a corrigendum and amendment in Clause 1, 1.2. Though it's by the IEEE, it is applicable to all international standards. Basically, a corrigendum is:

A document that only corrects editorial errors, technical errors, or ambiguities in an existing IEEE standard. A corrigendum does not introduce new material.

NOTE - A typical corrigendum may contain:
- Corrections to equations, tables or figures, or their associated numbering or citations in the text
- Corrections to technically incorrect sentences or paragraphs
