Fixed firefighting systems. Foam systems - Part 1: Requirements and test methods for components Ingestion-build-100580 in compliance with BS 2690-1151 Scope The requirements of this document set out the materials, construction, and performance of components intended for use in fixed foam fire fighting systems, and using foam concentrates conforming to EN 15681 to EN 15684. The components covered are: proportioners, sprayers, semi subsurface hose units, branchpipes, low medium expansion foam generators, high expansion foam generators, foam chambers, tanks and pressure vessels. Methods of test are
