BS ISO 12308:2017 pdf download – Plain bearings — Quality assurance of sample types — Definitions, applications and testing 1 Scope This document defines the types of plain bearing samples exchanged between purchaser and manufacturer. In the field of internal combustion engines and other series production, it is necessary to work with different types of samples depending on the purpose. Types of samples are as follows. — Samples used for tests and examinations which are carried out in the experimental stage and pilot lot stage. These include fitting samples, prototype samples and intermediate samples. — Samples used to prove that the quality is in accordance with the quality requirements (dimensions, material and performance specification). These include initial samples and reference samples and, if necessary, intermediate samples. NOTE See ISO 3534 (all parts) and ISO 9000 for further information. — Samples which give selective information about particular quality characteristics of a plain bearing, relating to their conformity with the specifications. These involve reference and characteristic modification samples. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

In the fields of application listed in Clause 1, the “Initial Sample Test Report” is used for the initial samples and the characteristic modification samples. The purchaser shall share the result of inspection with the manufacturer. The test results shall be kept by the manufacturer subject to agreement between the manufacturer and purchaser. 5 Marking All sample supplies shall be clearly marked as samples by the manufacturer in agreement with the customer. 6 Types of plain bearing samples, definition and manufacturing process, application and testing As described in Table 1.BS ISO 12308 pdf download.
