Although Malaysia consists of 13 States, there is only one law on weights and measures i.e. the Weights and Measures Act 1972. The Act relates to the use of legal units, standards of measurement and control (pattern approval and verification) of measuring instruments.
Under the Act, the custodian of weights and measures has been appointed and the weights and Measures Department formed. At the State level, the weights and measures department branches implement the various requirements of the Law, However, specific enquiry should be made to ascertain the legislative control applicable to a particular situation, for example taximeters, water meters and watt-hour meters are not included in the Weights and Measures Act.
The Weights and Measures Act 1972 requires that the measurement of all physical quantities for legal purposes be made traceable by means of reference to the custodian of weights and measures.
All instruments used in Malaysia shall be in SI units except for special cases of replacement of parts and in some specific industries.
Information on units and tables of weights and measures may be obtained from the Weights and Measures Act mentioned above,
The authority for legal metrology is:
Standards & Industrial Research Institute of Malaysia (SIRIM)
Persiaran Dato' Menteri
Section 2, P. O. Box 7035
4091 1 Shah AIam

Telephone: 60-3-559 1630/559 2601
Fax: 60-3-550 8095
SIRIM is responsible for maintaining the primary standards of the country, while the weights and Measures Department of the Ministry of Domestic Trade and Consumer Affairs is responsible for the day to day verification of equipment used for trade purposes.
SIRIM is the custodian of national standards.
Same as clause 3.2 above.
The weights and Measures Department has verification officers throughout the country.
SIRIM maintains a testing and calibration laboratory for pattern approval testing of trade measuring instruments. The Malaysian Accreditation Council is responsible for accrediting testing and calibration laboratories in the country.
The detailed list of equipment, range and tolerances of equipment subject to legal metrology are all gazetted under the Weights and Measures Act 1972.
SIRIM is responsible for the type or pattern approval to ensure that the design and the performance of the measuring instrument concerned meets certain criteria in order to ensure accurate and repeatable measurement. All new instruments used for trade purposes will be subject to pattern approval.
There is no formal mutual recognition procedure yet.
SIRIM possesses most of the testing and calibration facilities for pattern approval purposes. However, SIRIM will witness the testing meant for pattern approval anywhere in the world if the methods and equipment used are acceptable.
The fees for pattern approval is based on actual expenditure plus a nominal overhead. It varies from case to case.
A measuring instrument can only be used for trade purposes after it has been pattern approved and verified every year by the Weights and Measures Inspector. The instrument thus verified will be sealed and marked with a tag. The equipment mentioned can only be approved for trade use after it has met the appropriate limits of errors set by the Weights and Measures Act 1972.
The weights and Measures Department keeps the record of the type and number of equipment approved and reverified.
Fees for verification and reverification are gazetted in the Weights and Measures Act 1972.
Basically, there are two ways of disseminating standards of measurement. The first method of traceability is through the national accredited laboratories, while the second method is through the annual verification of equipment used for trade purposes.
SIRIM maintains the primary, secondary and tertiary standards of measurement, while the weights and Measures Department, research laboratories and accredited laboratories, and the industries maintain the secondary, tertiary and working standards. They are all traceable to SIRIM, the national custodian of weights and measures.
SIRIM is responsible for product certification.
SIRIM has adopted the ISO 9000 series in total and is responsible for the registration of companies which meet the requirement.
Four research officers and three supporting staff are involved in pattern approval functions in SIRIM, while there are more than 50 inspectors of weights and measures who are doing the annual verification of equipment.
Minimum qualification of research officers is basic university degree with Honours.
SIRIM provides technical training to the inspectors of weights and measures, while the legal training is obtained from the governments training agency.
The training provided is in the form of lectures and practicals on equipment and principles related to those specified in the Weights and Measures Act 1972.
The Trade Descriptions Act controls the sizes and contents of packaging.
The Enforcement Division of the Ministry of Domestic Trade and Consumer Affairs is responsible for the implementation of the Trade Description Act,
There are heavy fines and jail sentences for persons who contradict the Weights and Measures of Act 1972. the details of the penalty are all gazetted under the same Act.
