BIS Certification for Refillable Seamless Steel Gas Cylinders– IS 7285 (Part 2): Quenched and Tempered Steel Cylinders

IS 7285 (Part 2), governed by the Bureau of Indian Standards (BIS), covers the requirements for refillable seamless steel gas cylinders constructed from quenched and tempered steel with a tensile strength under 1100 MPa. This certification is necessary for manufacturers in India, as it validates that their cylinders are built to withstand the pressures associated with compressed gas storage and transportation, ensuring user safety.

Why is BIS Certification Necessary for Quenched and Tempered Steel Gas Cylinders?

BIS certification under IS 7285 (Part 2) is vital for ensuring that seamless steel gas cylinders meet key safety requirements when storing and transporting compressed gases. Given the high pressures and potential hazards, this certification provides assurance against risks like leaks, ruptures, and material failure, promoting consumer trust in the product’s safety and reliability.

Overview of Indian Standard IS 7285 (Part 2)

IS 7285 (Part 2) outlines the requirements for refillable seamless steel gas cylinders made of quenched and tempered steel with tensile strength below 1100 MPa. The standard specifies the use of durable, corrosion-resistant materials to ensure the cylinders can safely store compressed gases under pressure. It mandates a seamless design to enhance resilience and prevent weaknesses, while also requiring rigorous testing for pressure resistance, leakage, and environmental durability. The standard ensures that the cylinders maintain structural integrity and are safe for multiple refills over time, providing long-term reliability in various applications.

Process for BIS Certification

The BIS certification process for quenched and tempered steel gas cylinders under IS 7285 (Part 2) includes these steps:

1. Application Submission: Manufacturers submit detailed documentation on cylinder specifications, materials, and safety features.
2. Document Review: BIS evaluates the submitted documents to verify alignment with IS 7285 (Part 2) standards.
3. Factory Inspection: BIS inspectors visit the manufacturing facility to review production processes and quality control practices.
4. Sample Testing: Sample cylinders are tested in BIS-approved labs to ensure they meet IS 7285 (Part 2) requirements for safety and durability.
5. Certification Grant: Following successful testing and inspection, BIS grants certification, allowing the manufacturer to display the ISI mark on the product.
