IS 8442:2008 is the Indian Standard (BIS) for stand post type water and foam monitor for fire fighting -specification. This standard specifies the requirements for stand post type water and foam monitors used in fixed fire protection installations. It covers materials, construction, dimensions, performance criteria, and testing methods for monitors of different sizes.
