Scope: This standard specifies the types of plain bearing samples to be delivered between the user and the manufacturer. In the field of internal combustion engines and other mass production, it is necessary to use different types of prototypes according to the purpose of use. The type of sample refers to: --- The test and inspection samples used in the experiment and trial production stage, including assembly samples, prototype samples and pilot samples; --- Samples used to prove that the quality meets the quality requirements ( Dimensions, material and performance requirements), including batch samples and standard samples, including pilot samples if necessary. Note: See ISO3534 (all parts) and ISO9000 for more information. --- Sliding bearing samples that can provide specific quality characteristic information related to the technical requirements of sliding bearings, including standard samples and samples with changed characteristics.
