NEW STANDARDS

摘要

Changes in design concentrations are among the revisions to be found in new standards on gaseous fire extinguishing systems. Bob Whiteley brings us up to date. The BS ISO I452O semes of standards was first published in 2000, at which time BFPSA withdrew it Code of Practice for Gaseous Fire Extinguishing Systems, which had hitherto been the industry design guide and had formed the working document for the ISO committee. ISO has revised and updated these standards in the interim, and these have now been published as British Standards at the end of 2005 (agent parts) and General Requirements (Part 1) early this year.
