DEVELOPMENT OF MALAYSIAN STANDARDS
The Department of Standards Malaysia (STANDARDS MALAYSIA) is the national standards and accreditation body of Malaysia.
The main function of STANDARDS MALAYSIA is to foster and promote standards, standardisation and accreditation as a means of advancing the national economy, promoting industrial efficiency and development, benefiting the health and safety of the public, protecting the consumers, facilitating domestic and international trade and furthering international cooperation in relation to standards and standardisation.
Malaysian Standards (MS) are developed through consensus by committees which comprise balanced representation of producers, users, consumers and others with relevant interests, as may be appropriate to the subject at hand. To the greatest extent possible, Malaysian Standards are aligned to or are adoption of international standards. Approval of a standard as a Malaysian Standard is governed by the Standards of Malaysia Act 1996 [Act 549]. Malaysian Standards are reviewed periodically. The use of Malaysian Standards is voluntary except in so far as they are made mandatory by regulatory authorities by means of regulations, local by-laws or any other similar ways.
STANDARDS MALAYSIA has appointed SIRIM Berhad as the agent to develop, distribute and sell the Malaysian Standards.

NATIONAL FOREWORD The adoption of the ISO Standard as a Malaysian Standard was recommended by the Technical Committee on Alloy Steels under the authority of the Industry Standards Committee on Iron and Steel. This Malaysian Standard is identical with ISO 683-17:1999, Heat-treated steels, alloy steels and free-cutting steels - Part 17: Ball and roller bearing steels, published by the International Organization for Standardization (ISO) with the following modifications: a) in the source text, “this International Standard” has been replaced by “this Malaysian Standard”; b) the comma which is used as a decimal sign, has been replaced by a point; c) Clause/Subclause General
Modifications Replace the word “cast analysis” with “ladle analysis”
Explanation: Ladle analysis is more relevant compared to cast analysis. d) reference to International Standards should be replaced by equivalent Malaysian Standards as follows: Referenced International Standards

Compliance with a Malaysian Standard does not of itself confer immunity from legal obligations. NOTE. IDT on the front cover indicates an identical standard i.e. a standard where the technical content, structure, and wording (or is an identical translation) of a Malaysian Standard is exactly the same as in an International Standard or is identical in technical content and structure although it may contain the minimal editorial changes specified in clause 4.2 of ISO/IEC Guide 21-1.
