Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

This document was prepared by Technical Committee ISO/TC 123, Plain bearings, Subcommittee SC 5, Quality analysis and assurance.

This second edition cancels and replaces the first edition (ISO 12308:1994), which has been technically revised.

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.
