Introduction
A major motorcycle maker in Pune had to face the problem of their engines going bad all of a sudden in 2022. What was the reason? Piston pins that were breaking due to the devices’ normal operations, thus the company had to recall its products at a great cost and lose the trust of its clients. This instance from real life is a wake-up call for manufacturers and suppliers in India, saying that meeting the BIS Certification requirements for the steels that are going to be used in piston pins is not only a matter of compliance with the law but is also very important for the company’s reliability and business credibility in the long run.

What is IS 11952:1986?
IS 11952:1986 is the Indian Standard that specifies the requirements for steels used in piston pins (gudgeon pins). It sets the standard for chemical composition, mechanical properties, and testing procedures so that these parts of the engine can be capable, long-lasting, and safe under situations of high pressure. Manufacturers are obliged to follow this standard if they want to keep up with the required quality, lower the failure rate, and be compatible with the demands of the automotive industry both at home and abroad.
Key Points:
- It provides for the elements of the chemical composition to be limited: carbon, manganese, sulfur, and phosphorus.
- It also specified the mechanical characteristics, tensile strength, hardness, elongation.
- There is a list of compulsory testing procedures like bend tests, impact tests, and metallographic examination.
- It is a quality assurance system all over the batches to avoid the problem of piston pin failure in the engines.
- Forms the basis for BIS Certification for steels used in piston pins. ISI MARK
Why is BIS Certification Mandatory
BIS Certification is a compulsory thing for the steels used in piston pins, as these are the parts that not only impact the engine’s performance but also its safety. It essentially verifies that the steel adheres to the standards laid out in IS 11952:1986 in terms of the chemical composition, the mechanical strength, and the testing procedures. A certification is a quality guarantee which is one of the main reasons that the risk of failure is lowered and the reliability at heavy load engine situations is elevated. Besides, it helps the manufacturers in acquiring the trust of OEMs and customers, reducing the probability of legal and financial risks, and making it easier to get local and foreign markets.
Key Points:
- Material quality is guaranteed, thus the risk of engine failures is minimized.
- Verification of conformity to standard IS 11952:1986.
- Establishing trust with OEMs and customers.
- Reduction of the probability of legal, financial, and reputational risks.
- Facilitating the occurrence of exports and broader market acceptance.
