Introduction
BIS Certification for Short Pitch Transmission Precision Short-Pitch Transmission as per IS 2403 ensures that the chains meet a certain standard of quality, safety, and performance in the Indian market. The certification, which is given by the Bureau of Indian Standards (BIS), is mandatory for manufacturers and importers who want to ensure that their products meet standards of strength, accuracy of dimensions, and interchangeability. The certification will ensure that the chains work in a predictable manner in power transmission systems.
What is IS 2403?
IS 2403 Short-Pitch Transmissionis an Indian Standard that specifies the quality requirements, dimensions, and performance characteristics of short pitch transmission precision roller and bush chains used in mechanical power transmission. The Indian Standard IS 2403 was published by the Bureau of Indian Standards (BIS) and defines a number of factors such as chain size, strength, fatigue life, and interchangeability.
Key Points:
- IS 2403 is an Indian Standard that outlines requirements for short pitch transmission precision roller and bush chains.
- It is published by the Bureau of Indian Standards (BIS) to ensure quality and performance.
- The standard outlines the requirements for dimensional accuracy and interchangeability for smooth power transmission.
- It outlines the mechanical performance requirements such as tensile strength, fatigue, and wear resistance.
- Adherence to the IS 2403 standard ensures reliability, safety, and acceptance of transmission chains in the Indian market.
Why is BIS Certification Mandatory
BIS Certification Short-Pitch Transmission is a requirement to ensure that the products meet the specified Indian Standards in terms of quality, safety, and performance.
