BIS Certification for oil field application transmission steel roller chains and chain wheels was based on IS 14696:2000 which focuses on the performance, durability, and safety of oil field machinery and equipment. This standard outlines the basic chains and construction roller requirements for the dimensions, materials, mechanical properties and construction of transmission roller chains and chain wheels within oil field exploration and drilling. Chains and sprockets in oil fields are subject to extreme oil field operating conditions, which may include high load, extreme torque, and severe increased exposure wear and weathering. IS 14696:2000 certification means that oil chains, and components, will operate at optimal levels of strength, wear, and fatigue under extreme conditions, IS 14696:2000 also means that fatigue under extreme wear.
