GB/T 1149.10-2013
ActiveInternal combustion engines-Piston rings―Part 10: Keystone rings made of steel
内燃机 活塞环 第10部分：梯形钢环
Application Summary AI generated
This standard specifies the dimensions, material requirements, and inspection methods for keystone rings made of steel used in internal combustion engines. It is applied in the manufacturing and quality control of piston rings for heavy-duty diesel engines, particularly in automotive, marine, and industrial power generation equipment where high thermal and mechanical loads are present. The standard ensures compatibility and performance in engine assemblies requiring trapezoidal ring profiles to reduce carbon buildup and improve sealing under high-temperature conditions.
