Introduction

IS 3196 (Part 4) specifies the requirements for welded low carbon steel cylinders used for the storage of toxic and corrosive gases. These cylinders are crucial for industries where hazardous gases need to be contained and transported. Given the high risks associated with toxic and corrosive substances, IS 3196 (Part 4) ensures that these cylinders are designed to safely withstand internal pressure, corrosion, and potential leaks. BIS certification provides manufacturers with the assurance that their cylinders are safe, reliable, and compliant with Indian safety standards.

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

BIS certification for welded low carbon steel cylinders ensures that the cylinders used for storing toxic and corrosive gases adhere to the safety and performance standards outlined in IS 3196 (Part 4). These cylinders must be manufactured from high-quality materials that are resistant to corrosion and capable of withstanding the high-pressure environment created by liquefied gases. Compliance with these standards is critical to prevent accidents, such as leaks or ruptures, which could pose a significant risk to human health, the environment, and property. The ISI mark provides assurance that the cylinders have undergone rigorous testing and quality checks.

Overview of Indian Standard IS 3196 (Part 4)

Indian Standard IS 3196 (Part 4) outlines specifications for welded low carbon steel cylinders used to store toxic and corrosive gases. The standard emphasizes material requirements, ensuring the use of low carbon steel with specific mechanical properties to guarantee strength, flexibility, and corrosion resistance. It also defines design and construction guidelines, mandating safety features such as pressure relief valves and leak-resistant welding. Additionally, the cylinders must undergo rigorous testing, including pressure and leak tests, to verify their structural integrity. Safety mechanisms like pressure regulators and valves are required to prevent over-pressurization and leakage. The standard ensures that the cylinders are durable enough to withstand the corrosive effects of the gases they contain, offering long-term reliability and safety.

Process for BIS Certification

The process for obtaining BIS certification for welded low carbon steel cylinders under IS 3196 (Part 4) involves the following steps:

Application Submission: Manufacturers submit an application with technical details and product specifications.

Document Review: BIS reviews the provided documentation to ensure the cylinder design meets the requirements of IS 3196 (Part 4).

Factory Inspection: BIS conducts an inspection of the manufacturing facility to verify the production process and quality control measures.

Sample Testing: Samples of the cylinders are tested in BIS-approved laboratories to ensure they meet all relevant safety, pressure, and performance standards.

Certification Grant: After successful testing and inspection, BIS grants certification, allowing the cylinders to display the ISI mark, indicating compliance with safety standards.

Documents Required for BIS Certification

Manufacturers seeking BIS certification for welded low carbon steel cylinders must provide the following documents:

• Application form
