IS 3196 (Part 4)
Welded low carbon steel cylinders exceeding 5 litre Water capacity for low pressure liquefiable gases Part 4 Cylinders for toxic and corrosive gases
Summry
These are welded low carbon steel cylinders with water capacity over 5 litres, designed for storing low-pressure liquefiable gases, specifically toxic and corrosive gases. They are engineered to withstand pressure safely, resist corrosion, and ensure durability, making them suitable for industrial, laboratory, and chemical applications where hazardous gases are handled.
Why BIS Certificate is Mandatory for Welded low carbon steel cylinders exceeding 5 litre Water capacity for low pressure liquefiable gases Part 4 Cylinders for toxic and corrosive gases?
BIS certification is mandatory to ensure safety, quality, and compliance with Indian standards. These cylinders store toxic and corrosive gases, so certification ensures material strength, leak-proof construction, corrosion resistance, and pressure tolerance, reducing the risk of accidents, chemical exposure, and environmental hazards during storage, handling, and transport.
What is BIS Certified for Welded low carbon steel cylinders exceeding 5 litre Water capacity for low pressure liquefiable gases Part 4 Cylinders for toxic and corrosive gases?
The BIS certified specification for these cylinders is defined under IS 3224 (Part 4): Welded Low Carbon Steel Cylinders. It specifies chemical composition, mechanical properties, design, dimensions, welding quality, pressure testing, leak tests, and surface protection to ensure the cylinders are safe, durable, and suitable for toxic and corrosive gases in industrial applications.
