Introduction

When a Pune-based company of a mid-sized pneumatic tool tried to broaden its horizons by venturing into the industrial markets outside Maharashtra, they received a series of refusals. Their equipment was operating very well, but the customers were asking for certified steel compliance. The point was not the performance, rather it was trust. The problem was resolved by the BIS certification for steels under IS 5651:1987. By adhering to the standardized quality and safety requirements, the producer acquired the necessary trust, opened the doors for new contracts, and gained the confidence of industrial purchasers. Certification in India is not only regulatory but also a strategic tool for growth and getting accepted in the market. Bureau of India Standards
What is IS 5651:1987?
The IS 5651:1987 standard is the Indian Standard that details the criteria for steels used in pneumatic tools. It establishes the rules for chemical composition, mechanical properties, and testing methods so that the steels are safe, long-lasting, and can be used in industrial applications. Meeting this standard is very important for manufacturers to obtain market trust and be in line with the requirements of the regulatory authorities.
Key points:

- The standard defines chemical composition limits for carbon, manganese, sulfur, and phosphorus.
- Mechanical properties to be considered include tensile strength, yield strength, elongation, and hardness as given in the standard.
- The Standard describes the testing methods such as the destructive and non-destructive methods.
- Production batches of a company will showcase the same level of quality and reliability, leading to brand trust among consumers. ISI MARK
- Observance of the standards paves the way for market acceptance, legal compliance, and industrial safety.
Why is BIS Certification Mandatory
BIS certification is required for steels in pneumatic tools to maintain safety, quality, and conformity to the law. The certification serves as evidence that the material complies with the standards outlined in IS 5651:1987, which the industrial buyers and the government agencies use for dependable performance.
Key reasons:
- It guarantees product safety by ensuring uniform mechanical properties and consistent chemical composition.
- It serves as a reliable and trustworthy tool for industrial clients and government tenders.
- It acts as a safeguard against equipment failures, liability issues, and warranty-related problems.
- It is necessary for legal compliance in regulated industrial markets.
- It supports international marketing efforts, as exports are produced according to recognized Indian standards.
