Drafting rules

Clause numbering
Clauses are numbered from 1 in a single sequence. Subdivision beyond the fifth level is not permitted. A clause shall not be subdivided into a single subclause.
Verbal forms
Requirements use shall; recommendations use should; permission uses may; possibility uses can. The forms must, has to, and it is necessary that shall not be used to express requirements.
Deprecated wording
Do not use where possible, as appropriate, adequate, or sufficient in a requirement: such wording cannot be verified in assessment.
Numbers and units
The decimal sign is a full stop. Digit grouping uses a thin space, never a comma. Quantities are stated with their unit at first occurrence in each clause.
Cross-references
Refer to clauses by number, never by page. Undated references to other SQLBL deliverables admit all later editions; dated references do not.
Notes and examples
Notes and examples are informative and shall contain no requirements, permissions, or recommendations.
Header apparatus
Since the amendment of 2026-06-19, every published deliverable carries its current stage code, ICS field, price group and responsible committee in the document header.

Verbal forms are defined normatively on the conformance page; stage progression under Part 1 is tabulated in the stage codes table.
