Description
ISO defines requirements for the usage of abbreviations. As we are using some, we should stick to sec 8.3 and 8.4 of the ISO ruleset.
The names of organizations, and their abbreviated forms, shall be written as used by those organizations, in English, French or Russian.
and
The use of abbreviated terms shall be consistent throughout the document.
If a list of abbreviated terms is not given in the document (see Clause 17), then the first time that an abbreviated term is used, the full term shall be given with the abbreviated term following in brackets.
EXAMPLE 1 … the weighted root mean square (RMS) width of the active output interface optical spectrum …
Any abbreviated term should be in uppercase letters, without a full stop after each letter.
EXAMPLE 2 “RH” for “relative humidity”.
Occasionally, abbreviated terms in common use are written differently, either for historical or for technical reasons.
Technical specifications regarding marking may impose other requirements.
