Valve fittings for liquefied petroleum gas (LPG) cylinders
serve as essential safety components, providing secure gas containment and
controlled gas release. For cylinders exceeding 5 liters in water capacity, IS
8737 Part 2 specifies the standards for valve fittings on newly manufactured
LPG cylinders. BIS certification for these valve fittings confirms their
adherence to stringent safety and performance standards, ensuring secure use in
both residential and industrial applications.
Introduction
The Bureau of Indian Standards (BIS) mandates that valve
fittings for large LPG cylinders comply with IS 8737 Part 2. This standard sets
forth specific requirements for safety, leak prevention, and pressure handling,
minimizing the risks associated with LPG usage. BIS certification under this
standard allows manufacturers to display the ISI mark on valve fittings,
assuring consumers of compliance with national safety standards.
Why is BIS Certification Necessary for Valve Fittings on
LPG Cylinders?
Since LPG is a highly flammable gas, valve fittings must
meet rigorous safety standards to prevent leaks and ensure proper gas
regulation. BIS certification under IS 8737 Part 2 verifies that the fittings
meet essential safety requirements, reducing the risk of accidents, fires, or
gas leakage, and ensuring user safety.
Overview of Indian Standard IS 8737 Part 2
IS 8737 Part 2 outlines crucial safety and performance standards for LPG
cylinder valve fittings. These include leak resistance to prevent gas leaks,
pressure tolerance to withstand high LPG storage pressures, and corrosion
resistance for durability. The standard ensures secure gas regulation for safe
release and specifies impact resistance to protect fittings from mechanical
damage. These requirements collectively enhance the reliability, safety, and
longevity of valve fittings used in LPG cylinders.
Process for BIS Certification
