At present there are 22 verification branch offices and 3 verification centres within the organization of the Central Bureau of Weights and Measures, spreading over the country. Each verification branch office and verification centre performs under the Weights and Measures Law and the policy of DCR to inspect, verify all measuring instruments used for trade. In addition, each verification centre provides calibration services in its region for verification branch offices and customers from industry.
3.5 Instrument Calibration and Evaluation Systems
The Central Bureau of Weights and Measures is responsible for calibrating, inspecting and verifying all measuring instruments prescribed in the Weights and Measures Law. There is no other accredited organization or laboratory that can perform the duty related to legal metrology.
For voluntary application, not legal, there are laboratories accredited by Thai Laboratories Accreditation Scheme (TLAS) provide calibration and testing services for the public.

4. Range of Equipment Subject to Legal Metrology
All measuring instruments intended for trade use and covered by the Weights and Measures Law, must pass verification and be sealed with a verification mark before being put on the market or used.
5. Type Approval
There is currently no pattern approval function in the metrology system of Thailand. The Central Bureau of Weights and Measures will be the authority for issuing pattern approval certificates in the near future.
6. Verification (Conformity Assessment), Inspection and Reverification
6.1 Legal and Technical Requirements for Verification and Reverification
All 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, Branch offices or the organizations, manufacturers or repairers designated by DCR.
There are two types of verifications for the measuring instruments. The first verification of a measuring instrument, which has never been verified, is called an initial verification and the reverification after repairing and expiration of the term of validity for verification is called a reverification.
The requirements for verification or reverification are as follows:
- The instrument must operate within the appropriate limits of error that may be tolerated under the Ministerial Regulations.
- The instrument must provide graduations in a unit of measurement under Metric System or certain additional customary units of measurement within the meaning of Weights and Measures Law.
6.2 Range of Equipment Verified and Reverified and any Statistical Information Available
The range of equipment verified or reverified include the following:
- Non-automatic weighting instruments
- Automatic weighting instruments:
- Belt-Conveyor Scale Systems
- Automatic Bulk Weighing Systems
- Weights
- Liquid Measures
- Dry Measures
- Linear Measures:
- Measuring tapes
- Straight rules
- Fabric-Measuring Devices
- Liquid-Measuring Devices
- Mass Flow Meters
- Water Meters
- LPG -Measuring Devices
- Hydrocarbon Gas Vapor-Measuring Devices
- Rice Moisture Meters
6.3 Fee Structure
Fee for verification or reverification ranging from US $ 1-200 depending on type and capacity of measuring instrument.
