IS 8737
Valve fittings for use with liquefied petroleum gas cylinders of more than 5 litre water capacity Part 2 Valve fittings for newly manufactured LPG cylinders
Summry
Valve fittings for liquefied petroleum gas (LPG) cylinders are safety components used to control gas filling, storage, and withdrawal. Part 2 applies to valve fittings used in newly manufactured LPG cylinders above 5-litre water capacity, ensuring safe sealing, pressure control, and gas flow regulation.
Why BIS Certificate is Mandatory for Valve Fittings for Use with Liquefied Petroleum Gas (LPG) of up to 250 litre Water Capacity?
BIS certification is mandatory to ensure safety, reliability, and standard quality of LPG valve fittings. Since LPG is highly flammable, certified valves prevent gas leakage, accidents, and explosions. Mandatory BIS compliance protects consumers, ensures uniform manufacturing standards, and fulfills legal safety requirements in India.
What is BIS Certified for Valve Fittings for Use with Liquefied Petroleum Gas (LPG) of up to 250 litre Water Capacity?
BIS certified specification for LPG valve fittings is defined under IS 8737 (Part 2). It specifies requirements for design, material, pressure resistance, leakage prevention, dimensional accuracy, and testing. Compliance ensures valves are suitable for newly manufactured LPG cylinders and safe for long-term use.
