NZS 4541:2020

NZS 4541 provides an integrated set of rules for the design, installation, and maintenance of sprinkler systems, so that systems reliably protect against the loss of life and minimise property damage from fire by controlling the fire: within a specified area, and to allow escape before levels of toxic by-products of combustion become life-threatening. This standard is used extensively across the fire protection industry. New Zealand has one of the highest recorded successful operations of fire sprinkler systems, which can be attributed to the rigorous standards and associated legislation to which systems are installed and maintained. The revised standard addresses the following areas: Fire protection of tall (>25 meters) and large (>11,000 square meters) buildings, Seismic restraint of pipework to align with NZS 1170.5 Structural design actions; Part 5 Earthquake actions - New Zealand,¿¿ Inclusion of new technologies for car stackers and in-rack sprinkler systems for warehouses, editing of the standard and inclusion of the errata collected since the last revision in 2013.
