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).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 123, Plain bearings, Subcommittee SC 2,

Materials and lubricants, their properties, characteristics, test methods and testing conditions.

This third edition cancels and replaces the second edition (ISO 4382-1:1991), which has been technically

revised.
The main changes compared to the previous edition are as follows:
— Clause 2 "Normative references" has been updated;
— Clause 3 "Terms and definitions" has been implemented;
— Table 1 and Table 2 have been updated.
A list of all parts in the ISO 4382 series can be found on the ISO website.

Any feedback or questions on this document should be directed to the user’s national standards body. A

complete listing of these bodies can be found at www .iso .org/ members .html.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 4382-1:2021(E)
Plain bearings — Copper alloys —
Part 1:
Cast copper alloys for solid and multilayer thick-walled
plain bearings
1 Scope

This document specifies requirements for cast copper alloys for use in solid and multilayer thick-walled

plain bearings. It gives a limited selection of alloys currently available for general purposes.

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. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

ISO 4384-1, Plain bearings — Hardness testing of bearing metals — Part 1: Multilayer bearings materials

ISO 4384-2, Plain bearings — Hardness testing of bearing metals — Part 2: Solid materials

ISO 6892-1, Metallic materials — Tensile testing — Part 1: Method of test at room temperature

3 Terms and definitions
No terms and definitions are listed in this document.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— IEC Electropedia: available at https:// www .electropedia .org/
4 Requirements
4.1 General

If the purchaser's requirements necessitate limits for any element not specified, or limits different from

those already specified, these should be agreed upon between supplier and purchaser.

WARNING — Lead's (Pb) toxicity has been recognized, and its use has since been phased out of

many applications. However, many countries still allow the sale of products that expose humans

to lead. Lead is a neurotoxin (see Figure 1).
