IS 3196 (Part 1)
Welded low carbon steel gas cylinder exceeding 5 litre water capacity for low pressure liquefiable gases Part1 Cylinders for liquefied petroleum gas (LPG)
Summry
Welded low carbon steel gas cylinders are containers designed to safely store low-pressure liquefiable gases, primarily LPG, with a water capacity exceeding 5 litres. Made from high-quality low carbon steel, these cylinders provide durability, leak resistance, and corrosion protection, ensuring safe handling, storage, and transportation of liquefied gases.
Why BIS Certificate is Mandatory for Welded low carbon steel gas cylinder exceeding 5 litre water capacity for low pressure liquefiable gases Part1 Cylinders for liquefied petroleum gas (LPG)?
BIS certification is mandatory to ensure LPG cylinders meet Indian safety standards for material, design, strength, and leak prevention. It protects consumers from accidents, explosions, and gas leaks. Certification guarantees consistent manufacturing quality, compliance with statutory regulations, and enhances public safety in homes, industries, and commercial usage.
What is BIS Certified for Welded low carbon steel gas cylinder exceeding 5 litre water capacity for low pressure liquefiable gases Part1 Cylinders for liquefied petroleum gas (LPG)?
A BIS certificate is an official approval from the Bureau of Indian Standards that a product complies with Indian safety and quality standards (IS 9572 for LPG cylinders). It ensures the cylinder meets prescribed mechanical strength, corrosion resistance, leak-proof design, and safety requirements for safe handling and storage of liquefied petroleum gases.
