ISI / BIS Certification for Steel for the manufacture of Laminated Springs ( Railway Rolling Stock ) Part-1 Flat Sections-Specification

Iron and carbon make up the majority of this versatile and extensively used alloy, with trace quantities of manganese, silicon, sulfur, and phosphorus. It is a vital material in many different sectors and applications because of its outstanding strength, resilience, and versatility.

The steel that is used to make flat parts of laminated springs is essential for many uses, including as heavy machinery and railroad rolling stock. Laminated springs are a crucial part of railway cars because they absorb stress and provide suspension. Steel must adhere to certain specifications when it comes to the flat parts of laminated springs in order to guarantee the best possible performance. High-carbon steel, alloy steel, and speciality spring steels are often utilized steel types for producing laminated spring flat sections.

The specifications list the technical criteria and requirements that steel, mostly flat pieces, used to make laminated springs for railway rolling stock, must fulfill. To guarantee the performance, dependability, and safety of laminated springs in railroad rolling stock, certain requirements must be met. 

The required ISI Certification Scheme under IS standard IS 3885 (Part-1): 1992 includes standards for all types of steel used in the manufacturing of laminated springs (railway rolling stock) part-1 flat sections. 

The requirements for hot-rolled flat steel sections used in the production of laminated springs for railroad rolling stock are described in this standard. Detrimental defects such as seams, creases, overlaps, cracks, deep cavities, grooves, excessive scaling, and similar problems that might cause cracking during the hardening process or adversely influence performance must be absent from the hot-rolled material. There should be no bends, twists, or abnormalities in the surface's texture, and it should be rather smooth.

Without the ISI Mark, this product cannot be marketed, imported, or exported into the Indian consumer market.

About ISI / BIS Certification

Indian Standards Institute, or ISI was renamed the Bureau of Indian Standards (BIS) in 1987. The official mark that the Bureau of Indian Standards provides for manufacturers of various goods is the ISI Mark. It is used to indicate compliance with Indian standards (IS) set by the Bureau of Indian Standards (BIS) and has been used as a conformity marking for industrial products. Manufacturers received permission from BIS to use the ISI Mark on items that comply with relevant Indian requirements through the product certification program. 

Only manufacturers (domestic or foreign) who produce the finished product will be awarded ISI Certification. This will not be given to any product importers, traders, dealers, or distributors.

Process of ISI / BIS Certification

There are two approaches for Indian manufacturers to become certified with the ISI Mark:

• Regular Procedure
• Simplified Procedure 

Regular Procedure

With the possible exception of cases deemed "All India first," which might take up to 180 days, the licensing procedure is expected to be finished in 120 days. This timeline starts on the day the application is received, assuming that at different points in time the documentation, unit assessment, and product conformance are all deemed acceptable.

Step 1: Manufacturing Unit Customization in Compliance with Applicable Indian Standards

• Identifying the applicable Indian Standard
• Establishing in-house testing facilities as per the Standard's requirements

Step 2: Submission of the Application Form

• Preparing an Internal Test Report for the product by the relevant Indian Standard
• Compiling all necessary documents
• Completing the Online Application Form
• Online payment of application fees directly to BIS
• Submitting hard copies of the Application Form with all enclosures to the relevant Branch Office (BO) of BIS

Simplified Procedure

This is a much faster process than the standard procedure. After a factory inspection is deemed satisfactory and the initial evaluation establishes that the sample complies with the applicable Indian Standard(s), the license application process is expected to be finished in 30 days.

Step 1: Adapting the Manufacturing Unit to Comply with the Relevant Indian Standard

• Identifying the applicable Indian Standard
• Establishing in-house testing facilities to meet the Standard's requirements

Step 2: Sample Testing

• Obtaining the necessary certificate for raw materials (Material Test Certificate - MTC)
• Conducting product sample testing at a BIS-recognized testing laboratory
