Introduction
A large industrial gas supplier in Pune once recounted the story of when one of their containers of imported cylinders was stuck at port for a period of weeks. Everything was in order according to global standards, apart from the matter of an elusive requirement. They did not have the BIS Certification for refillable seamless steel gas cylinders normalized steel cylinders under IS 7285 Part 1. The delay in issuing the certification had halted deliveries to hospitals and placed incredible pressure on cash flow.Bureau of Indian Standards
What that provider experienced is commonplace in India’s compliance driven market space. Cylinders are delivered with high pressure gases and there can be no tolerance for any flaws in the material or manufacturing processes. In the event of a failure, the performance and medical safety of the cylinder can be compromised, exposing the manufacturer or importer to commercial risk, legal liabilities, and reputational harm. When manufacturers and importers obtain BIS approvals sooner in the operating cycle, they will avoid the disruption and gain a competitive advantage for their business.
What is IS 7285 Part 1?
IS 7285 Part 1 is the Indian standard regulations regarding safety and manufacturing requirements for reusable seamless steel gas cylinders constructed from normalized steel, which allows the cylinders to safely contain and transport various high-pressure industrial and medical gases.ISI MARK
Key Points
• Applies only to seamless, normalized steel cylinders
• Covers design, wall thickness, and material quality
• Requires strict heat treatment and non-destructive testing
• Mandatory for sale and use in the Indian market
• Compliance supports BIS Certification and legal acceptance
