Plain Bearings - Quality Assurance of Sample Types -

Definitions, Applications and Testing

1 Scope

This Standard specifies the sample types of plain bearings used for delivery between

the user and the manufacturer.

In the field of internal combustion engines and other mass production, it is necessary

to adopt different sample types in accordance with the purpose of use.

The sample types refer to:

---Testing and inspection samples used for the experimental and trial production

stages, including assembly samples, prototype samples and intermediate

samples;

---Samples used to prove that the quality complies with the quality requirements

(size, material and performance requirements), including batch samples and

standard samples, and if necessary, intermediate samples.

NOTE: see ISO 3534 (all parts) and ISO 9000 for more information.

---Plain bearing samples that can provide specific quality characteristic information

related to the technical requirements of plain bearings, including standard

samples and characteristic-changing samples.
