BIS Certification for Seamless Steel Tubes for Manufacturing High-Pressure Gas Cylinders Specification IS 12620

Obtaining the ISI mark on mandatory products is a compulsory compliance requirement for manufacturers and importers who want to sell these products in the Indian market. Apart from the IS 12620 standard, it is going to be mandatory, and there is no final deadline for implementation. It might also come under voluntary products. This standard defines the technical and quality requirements for steel tubes, ensuring that the finished cylinders and transporting high-pressure gases. If the manufacturer wants to build trust in the Seamless Steel Tubes for Manufacturing High-Pressure Gas Cylinders product quality, safety, and reliability standards set by the Indian government.

Understand the steps, costs, timeline, and requirements for obtaining BIS Certification as per IS 12620, as well as the roles and responsibilities of a BIS Consultant.

BIS License for Seamless Steel Tubes Overview

A BIS Certification of IS 12620 refers to mandatory verification of seamless steel tubes (or flashings) used in the fabrication of high-pressure gas cylinders. 

The full title for these standards is “IS 12620” Seamless Steel Tubes For The Manufacture of High-Pressure Gas Cylinders.  IS 12620 provides the technical and quality requirements of steel tubes in the manufacturing and production of high-pressure gas cylinders intended to ensure safe and reliable handling. Utilization, storage, and transportation of high-pressure gas, etc. The standards outlined in IS 12620 are established by the Bureau of Indian Standards (BIS) Metallurgical Engineering Division.

Key Specification of IS 12620

IS 12620 is the Bureau of Indian Standards (BIS) specification for seamless steel tubes used for the production of high-pressure gas cylinders. The specification, most recently reaffirmed in 2018, describes the requirements for the tubes used to eventually store permanent and high-pressure liquefiable gases.

• Material: The Standard states that seamless steel tubing is specified, indicating that the cylinders are made of manganese steel, specifically intended for use with permanent and high-pressure liquefied gases.
• Manufacturing: The tubes should be manufactured as seamless, meaning they are a single continuous piece of metal without a welded seam. It is particularly important to avoid any weak points in the use of the tubing in high-pressure applications.
• Intended use: The tubes are used for the manufacturing of high-pressure gas cylinders.
• Testing: The specification states that several other Indian Standards are referenced for testing with respect to testing steel tubes and for the beam impact test (V-notch) of steel.
• Quality control: As a fully binding Indian Standard, the material following IS 12620 must follow a strict system of inspection, testing, and quality control that is subject to BIS supervision.
• Amendments: The Standard has been amended at least once since its first publication.

BIS Requirement for Seamless Steel Tubes Certification in India

Here is the basic requirements of obtaining the ISI Mark for IS 12690:

• Applicable Standard: Seamless steel tubes must comply with IS 12620, which covers Steel Tubes for Structural Engineering and General Engineering Purposes.
• Certification Requirement: Manufacturers and importers must obtain BIS certification to sell seamless steel tubes in India.
• Testing Parameters: Tubes must meet specific requirements for Chemical composition, Mechanical properties, Dimensional tolerances, Surface finish, and appearance
• Quality Control: Manufacturers must have a Quality Control Manual detailing production processes, inspection methods, and test procedures.
• Factory Inspection: BIS conducts periodic factory inspections to verify manufacturing processes, quality control, and compliance.
• Testing: Samples must be tested at a BIS-recognized laboratory to confirm compliance with IS 12620.
• Documentation: Required documents include the application form, process flow charts, test reports, quality manuals, and calibration certificates.
• Penalties for Non-Compliance: Sale or import of non-BIS-certified seamless steel tubes is prohibited and may lead to fines or legal action under the BIS Act.

ISI Certification Process for Seamless Steel Tubes

To obtain the Bureau of Indian Standards certificate for your product, you can follow these steps: 

• Application Procedure: First, the manufacturers must register on the BIS portal and complete an application form for a license or certificate.
• Documentation Procedure: This includes gathering the required documents, which include factory licenses, quality control plan, raw materials specifications, and so on.
• Testing Procedure: Samples will be sent for chemical composition testing to a BIS-recognized laboratory. 
• Factory Assessment: BIS officers will conduct an assessment of the quality control documentation and factory layout.
• License Approval: If the factory assessment was approved to the satisfaction of BIS, they would grant a license to the manufacturer for the Standard mark, which indicates the tin ingots conform to the applicable Indian Standards.

Timeline for BIS License of Seamless Steel Tubes IS 12620

The time it takes to acquire a BIS license for seamless steel tubes under IS 12620 depends on where the manufacturer is located. For Indian (domestic) manufacturers, the BIS license will generally take 1-2 months. This shorter timeline is due to the ease of product testing, submitting documents, and scheduling factory inspections/visits when a manufacturer is located in India.

For manufacturers that are based outside of India, it can take 6 months or longer. The time needed is due to the additional steps of shipping samples of the products to be tested to a lab, coordinating an audit of the factory by BIS, and dealing with all types of cross-border document flow, delays, and if and when the paperwork/process/report is incomplete or needs to be worked through. These are time estimates based on the assumption that all reasonable and timely documentation and testing have been completed.

Documents Required for BIS Certification of IS 12620

To obtain BIS certification for products that fall under IS 12620, the standard for seamless steel tubes used in high-pressure gas cylinders, you need to submit a comprehensive set of documents related to the legal, technical, and quality control aspects of your manufacturing facility. Let's review the required documents:

• Application Form
• Business Registration Documents
• Manufacturing Process Details
• Product Details
• Quality Control Documents
• Raw Material Information
• Testing Documents
• Factory Layout and Infrastructure
• Marking and Labeling Details
