BIS Certification for Refillable Seamless Steel Gas Cylinders– IS 7285 (Part 1): Normalized Steel Cylinders

Introduction

IS 7285 (Part 1), established by BIS, specifies standards for refillable seamless steel gas cylinders made of normalized steel, covering requirements for safe construction, pressure resistance, and durability. The BIS certification under IS 7285 (Part 1) is mandatory for manufacturers aiming to supply seamless steel cylinders in India, ensuring the cylinders adhere to stringent safety measures essential for handling compressed gases.

Why is BIS Certification Necessary for Seamless Steel Gas Cylinders?

The BIS certification under IS 7285 (Part 1) for refillable seamless steel gas cylinders ensures that the cylinders meet essential safety standards for handling compressed gases. Given the high pressures and potential hazards associated with storing gases, certification helps to prevent risks like leaks, explosions, or ruptures, assuring both the manufacturers and users of the cylinder’s safety and durability.

Overview of Indian Standard IS 7285 (Part 1)

IS 7285 (Part 1) specifies the requirements for refillable seamless steel gas cylinders made from normalized steel, ensuring their safety and performance in storing and transporting compressed gases. The standard outlines material specifications, requiring high-grade normalized steel for corrosion resistance and structural integrity. It mandates seamless construction for enhanced strength and the ability to withstand high-pressure conditions. Rigorous leak testing and pressure tolerance checks ensure the cylinders can safely contain compressed gases, while compatibility with a range of gases is also ensured. Additionally, the standard sets durability criteria to ensure the cylinders remain reliable through regular refilling and extended use.

Process for BIS Certification

The BIS certification process for refillable seamless steel gas cylinders under IS 7285 (Part 1) includes these steps:

Application Submission: Manufacturers submit an application detailing the cylinder’s specifications, production process, and intended gas storage.

Document Review: BIS reviews technical documents to confirm compliance with IS 7285 (Part 1) specifications.

Factory Inspection: A BIS team conducts a factory inspection to assess manufacturing practices and ensure quality control standards are met.

Sample Testing: Cylinder samples are tested in BIS-approved laboratories for compliance with IS 7285 (Part 1) requirements, focusing on pressure resistance and leak integrity.

Certification Grant: Upon successful testing and inspection, BIS grants certification, allowing the manufacturer to display the ISI mark on certified cylinders.

Documents Required for BIS Certification

For BIS certification under IS 7285 (Part 1), manufacturers need to provide:
