DEPARTMENT OF STANDARDS MALAYSIA
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.
For the purposes of Malaysian Standards, the following definitions apply:
Revision: A process where existing Malaysian Standard is reviewed and updated which resulted in the publication of a new edition of the Malaysian Standard.
Confirmed MS: A Malaysian Standard that has been reviewed by the responsible committee and confirmed that its contents are current.
Amendment: A process where a provision(s) of existing Malaysian Standard is altered. The changes are indicated in an amendment page which is incorporated into the existing Malaysian Standard. Amendments can be of technical and/or editorial nature.
Technical corrigendum: A corrected reprint of the current edition which is issued to correct either a technical error or ambiguity in a Malaysian Standard inadvertently introduced either in drafting or in printing and which could lead to incorrect or unsafe application of the publication.
NOTE: Technical corrigenda are not to correct errors which can be assumed to have no consequences in the application of the MS, for example minor printing errors.
STANDARDS MALAYSIA has appointed SIRIM Berhad as the agent to develop, distribute and sell Malaysian Standards.

Foreword
This Malaysian Standard was developed by the Technical Committee on Steel Bars, Wire Rods and Wire Products under the authority of the Industry Standards Committee on Metallic Materials and Semi-finished Products.
Major modifications in this revision are as follows:
a) the title of this standard has been amended from “Hot-rolled steel bars for the
reinforcement of concrete - Specification” to “Steel for the reinforcement of concrete - Weldable reinforcing steel - Bar, coil and decoiled product - Specification”; and
b) a third ductility class has been added.
This standard has been developed so that it can be used in conjunction with MS EN 10080:2013. Definitions, symbols, steelmaking and manufacturing processes, routine inspection and testing, test methods, identification of the manufacturer and technical class and verification of mechanical properties in the case of dispute are all taken from MS EN 10080:2013.
This Malaysian Standard cancels and replaces MS 146:2006, Hot rolled steel bars for the reinforcement of concrete - Specification (Third revision).
Compliance with a Malaysian Standard does not of itself confer immunity from legal obligations.
