Specification of plastics-bronze-steel backing triplelayer self-lubricating materials - Part 2: Plastic overlay with modified POM 1 Scope This part of GB/T 27553 specifies the structural characteristics, technical requirements and test methods of plastics(modified POM)-bronze-steel backing triplelayer self-lubricating materials. This part of GB/T 27553 is applicable to the plastics(modified POM)-bronze-steel backing triplelayer self-lubricating materials (hereinafter referred to as "plastic overlays"), which can be post-processed into wrapped bushes, thrust washers, sliders, guide rails and other forms of products. 2 Normative references The following referenced documents are indispensable for the application of this document.
