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

The BIS certification process for LPG valve fittings under IS 8737 Part 2 includes:

1. Application Submission: Manufacturers submit an application with relevant product details and technical specifications.
2. Document Review: BIS reviews the documents to verify conformity with IS 8737 Part 2.
3. Factory Inspection: BIS conducts an inspection to ensure manufacturing quality and process compliance with safety standards.
4. Sample Testing: Valve samples undergo testing at BIS-accredited labs to confirm compliance with safety and performance criteria.
5. Certification Approval: After successful inspection and testing, BIS grants certification, allowing the ISI mark on the valve fittings.
