This Standard incorporates Amendment No. 1 (June 2000). The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure, or part thereof affected.

The objective of this edition is to include changes that reflect recent advances in technology and to refine the content for clarity and conciseness.

Significant changes have been made to Section 3 concerning exposure protection, and to Section 5 relating to protection of concealed spaces. Sections 10, 11 and 12, in respect to hydraulic calculation methods, have also received attention. Section 9, Light hazard class systems, has been entirely rewritten to include more useable and up-to-date parameters for the design of this class of system. The definitions clauses have been enlarged and the informative text for occupancy classification is set out in an appendix.
