Question: Are there any relevant standards or guidelines for piston ring support rings?
Use it and see which one is better; that will help you determine your standards for selection. :D
If you are referring to products such as filled polytetrafluoroethylene piston rings, there are industry standards in the machinery sector; these standards came into effect in April 2020, under the title JB/T 13632-2019, \"Filled Polytetrafluoroethylene Piston Rings for Oil-Free Reciprocating Piston Compressors\". I’m the drafter, haha:):):):) Hefei Yimi Technology Co., Ltd. — safeguarding compressor efficiency
JB T 5447-1991 Cast iron piston rings for reciprocating piston compressors; JB T 6290-1992 Metallographic testing of cast piston rings for internal combustion engines. ISO 6621-1: Vocabulary – 1986; Standards for piston rings in internal combustion engines. GB T 1149.1-1994 General rules for piston rings in internal combustion engines; GB T 1149.4-1994 Technical requirements for piston rings in internal combustion engines; GB T 1149.6-1994 Inspection methods for piston rings in internal combustion engines. GB T 14222-1993 Rectangular piston rings for internal combustion engines; QC T 284-1999 Metallographic standards for ductile iron piston rings in automotive and motorcycle engines
I can’t get it online. Could you share it? I want to learn it*
