Introduction

IS 3196 (Part 2) sets the safety and design standards for welded low carbon steel gas cylinders exceeding 5 liters water capacity for liquefiable gases other than LPG. These cylinders are typically used for industrial purposes and require strict adherence to safety protocols to minimize the risks associated with storing hazardous or flammable gases. Obtaining BIS certification under IS 3196 (Part 2) is necessary for manufacturers to ensure compliance with national standards, allowing their products to be safely used in various industries.

Why is BIS Certification Necessary for Welded Low Carbon Steel Cylinders for Liquefiable Gases?

BIS certification ensures that welded low carbon steel gas cylinders meet stringent safety and performance standards. These cylinders store gases under low pressure, making them susceptible to safety risks like leaks, pressure failure, and corrosion. The certification process ensures that the cylinders comply with key standards such as material strength, pressure tolerance, and durability. This certification helps manufacturers provide safe and reliable products, ensuring protection for users in industrial and commercial settings.

Overview of Indian Standard IS 3196 (Part 2)

Indian Standard IS 3196 (Part 2) specifies the requirements for welded low carbon steel cylinders used to store liquefiable gases other than LPG. It ensures the cylinders are made from durable, corrosion-resistant low carbon steel, capable of withstanding the internal pressure of liquefiable gases. The design incorporates essential safety mechanisms such as pressure relief valves and secure seals to prevent leaks and ruptures. The cylinders undergo rigorous performance testing, including pressure tolerance and leak prevention assessments, to guarantee their structural integrity and safe operation in various conditions. Compliance with IS 3196 (Part 2) ensures reliable and safe storage for a wide range of liquefiable gases in industrial and commercial applications.

Process for BIS Certification

The process for obtaining BIS certification for welded low carbon steel cylinders under IS 3196 (Part 2) follows several critical steps:

Application Submission: Manufacturers submit an application with detailed product specifications, factory details, and quality control documentation.

Review of Documentation: BIS reviews the submitted documents to verify compliance with IS 3196 (Part 2) standards.

Factory Inspection: BIS conducts an on-site inspection of the manufacturing facility to ensure that the production processes meet safety and quality standards.

Sample Testing: BIS-approved laboratories test sample cylinders to assess their performance under pressure, leak testing, and structural integrity.

Certification Grant: Upon successful inspection and testing, BIS grants certification, allowing the manufacturer to affix the ISI mark on their cylinders, ensuring their compliance with national standards.

Documents Required for BIS Certification

To apply for BIS certification, manufacturers must provide the following documents:

• Application form
• Product technical specifications and drawings
• Test reports from BIS-approved laboratories
• Quality control and manufacturing process documentation
• Factory inspection reports
• Business registration documents
• Declaration of compliance with IS 3196 (Part 2) standards

These documents are essential to demonstrate adherence to the safety standards specified in the IS 3196 (Part 2) standard.
