Foreword
This standard is equivalent to international standards ISO 6691.2000 "thermoplastic polymer plain bearings classification and labeling" (in English).
This standard is equivalent translation ISO 6691.2000.
For ease of use, this standard made the following editorial changes.
--- "This International Standard" be replaced by "this standard";
"." --- With a decimal point instead of a comma as the decimal point, "";
--- Delete foreword international standards;
--- As international standards normative references listed full, adopt standard time increased our four international standards referenced in the text, respectively
