GET BIS CERTIFICATION FOR CHLORINATED POLYVINYL CHLORIDE (CPVC) PIPES FOR AUTOMATIC SPRINKLER FIRE EXTINGUISHING SYSTEM IS 16088:2012
Chlorinated polyvinyl chloride is a thermoplastic produced by chlorination of polyvinyl chloride resin. CPVC is significantly more flexible than PVC, and can also withstand higher temperatures. Uses include hot and cold water delivery pipes and industrial liquid handling.
A fire sprinkler system is a type of automatic extinguishing system (AES) that prevents fire growth and spread by releasing water through a series of sprinkler heads connected to a distribution piping system.
BIS is a statutory institution established under the Bureau of Indian Standards Act,1986 to promote harmonious development of the activities of standardization, marking and quality certification of goods and attending to connected matters in the country.
Chlorinated polyvinyl chloride (CPVC) pipes for automatic sprinkler fire extinguishing system product has been specified in IS 16088:2012 by Bureau of Indian Standards.
SCOPE :
This standard covers requirements and test methods for chlorinated polyvinyl chloride pipes for installation of automatic sprinkler fire extinguishing systems in accordance with IS 15105 for light hazard occupancies in maximum area of 125 m2. This standard also covers recommendatory information for jointing of pipes and installation of CPVC piping system. These CPVC pipes are recommended for wet piping system only.
