1. LAWS OF METROLOGY

The Law concerning Legal Metrology is the Weights and Measures Law B.E. 2466. This Law and Ministerial Regulations (the Regulation issued for the execution of this Law) have been enacted since 1923.

The Department of Commercial Registration has proposed the new weights and Measures Law to replace the Weights and Measures Law B.E. 2466. This new law has been approved by the cabinet and is waiting to be considered by the parliament in the next parliament session. It is expected that the new Weights and Measures Law will be enacted by the end of 1994.

1.1 Legal requirements for traceability

As defined in the Weights and Measures Law, all measuring instruments and the measurement of physical quantity for commercial or legal purposes must be calibrated, inspected and verified by standard of measurement or certified reference materials.

2. LEGAL UNITS OF MEASUREMENT

The Thai official legal unit is the Metric System, together with certain additional customary units adapted to this System.

3. STRUCTURE OF METROLOGICAL CONTROL AUTHORITIES

3.1 National organisation for legal metrology:

The Department of Commercial Registration (DCR)
Ministry of Commerce
Maharaj Road, Bangkok 10200
Thailand
Telephone: 662-224-0031
Fax: 662-225-8493
The Central Bureau of weights and Measures of Thailand has the responsibility for all legal metrology activities, and acts under the direction of the Department of Commercial Registration (DCR).. The Central Bureau of Weights and Measures is authorized to issue and deliver licenses to manufacturers, importers, repairers and sellers of weighing and measuring instruments prescribed or permitted to be used in connection with the system established by the Weights and Measures Law. The functions of the Central Bureau of weights and Measures include the registration, verification, inspection and general control of licenses, and of the weighing and measuring instruments used in Thailand, in conformity with the requirements of the Law or Ministerial Regulations.

3.2 Custodian of National Standards

Currently there is no national organisation established to keep or maintain all national standards in Thailand. The Department of Commercial Registration has the authority and responsibility, by law, to keep and maintain the national standards of mass and length. For the other national primary standards there are several organisations responsible for keeping and maintaining them.

It has proposed a new Law to establish the National Metrology Institute to be responsible for the maintenance of all national standards, This law will be presented to Parliament soon.

3.3 National organisation responsible for maintaining primary standards

See clause 3.2.

3.4 Regional and local verification organisations

At present there are 38 verification branch offices, within the organisation of the Central Bureau of weights and Measures, spreading over the country. Each verification branch office performs under the Weights and Measures Law and the policy of DCR to inspect, verify and calibrate all weighing and measuring instruments used in trade. Inspectors also have the authority to issue the certifications of instruments for commercial use.

3.5 Instrument calibration and evaluation systems

The Central Bureau of Weights and Measures is acting as the organisation to provide and maintain calibration laboratories for calibrating, inspecting and verifying all trade measurement instruments prescribed in the Weights and Measures Law. There is no other accredited organisation or laboratory that can perform the duty related to legal metrology. 
For voluntary application, not legal, there are five main organisations which provide calibration to the public:

4. RANGE OF EQUIPMENT SUBJECT TO LEGAL METROLOGY

All measuring instruments intended for commercial use and covered by the Weights and Measures Law, must have a certificate of approval issued by the Central Bureau of weights and Measures before they can be installed or used.

5. TYPE APPROVAL ( i.e. PATTERN APPR0VAL)

There is no type approval function in the metrology system of Thailand. This subject has being studied and will be established in the near future.

6. VERIFICATION ICONFORMITY ASSESSMENTI, INSPECTION AND REVERIFICATION

6.l Legal and technical requirements for verification and reverification

Any company dealing with the business of manufacturing, or importing, or selling or repairing weighing or measuring instruments, shall have a licence under Weights and Measures Law issued by the Central Bureau of Weights and Measures.

All weighing and measuring instruments prescribed for trade use or any other applications under this Law, or the Ministerial Regulations, must be verified by the Central Bureau of Weights and Measures and marked with verification mark.

All weighing or measuring instruments repaired by the repairer must be submitted to the Central Bureau of Weights and Measures for reverification before being returned.

The requirements for verification or reverification are as follows:

6.2 Range of equipment verified and reverified and any statistical information available

The range of equipment verified or reverified include the following:

6.3 Fee structure

Fees for verification or reverification range from US $1 - 40 depending on type and capacity of weighing or measuring instrument.

7. ACCREDITATION AND CERTIFICATION SYSTEMS

7.1 Accreditation systems for legal metrology, calibration and testing laboratories. Traceability to national, regional, international or foreign measurement standards.

There is no accreditation system for legal metrology in Thailand since prescribed in the Weights and Measures Law, the Central Bureau of Weights and Measures is the only authorized organisation that can perform any activity related to legal metrology.

7.2 Legal and applied metrological activities in products certification

Thailand Industrial Standard Institute (TISI) is the only authorized government organization that provides products certification, The license to use the Standards Mark on any product must be approved by TISI.

7.3 Legal and applied metrological activities in ISO 9000 quality management systems

ISO 9000 has been recently introduced to the industrial system in Thailand. Several laboratories or organisations, accredited by TISI, can provide the certificate in the part of the whole system. The Central Bureau of weights and Measures is acting as a supporting organisation to provide and issue the certificate in mass, length and weighing instruments in connection with ISO 9000 certification. However, for the whole system, quality certification to ISO 9000 must be approved and provided by TISI.
