As the competent authority of weights and measures in Taiwan, the Bureau of Standards, Metrology and Inspection (BSMI) under the Ministry of Economic Affairs is responsible for establishing and maintaining the nation's highest measurement standards. By providing precision measurement technologies and application services across diverse industries, the BSMI has established 133 sets of national measurement standards across 17 fields, which have achieved mutual recognition with 102 economies worldwide.

To showcase Taiwan's achievements in establishing the highest measurement standards and its innovative R&D in calibration and measurement technologies, the BSMI held a press conference titled "Precision Measurement Technology: Supporting Industry and Safeguarding Public Livelihoods," highlighting its achievement in " Harmonizing the Use of Weights and Measuring Units to Ensure Measurement Accuracy."

To ensure fairness in commercial transactions and the credibility of law enforcement, the BSMI has designated 22 categories of legal measuring instruments subject to mandatory verification. Every unit-including electricity meters, water meters, diaphragm gas meters, weighing instruments, taximeters, breathe alcohol testers and analyzers, oil meters, and speedometers used in law enforcement-must undergo verification before being imported or released from the factory.

The BSMI annually verifies over 4 million metrology devices. Besides, the BSMI conducts market surveillance and inspections and sample testing on more than 60,000 metrology devices currently in use each year, ensuring that every device bearing the "Verification Mark" (the Chinese character 'Picture as attachment file') remains accurate and reliable.

To facilitate industrial advancement, BSMI's National Measurement Laboratory (NML) provides over 5,000 standard calibration services annually. By disseminating the highest measurement standards to 2,200 calibration and testing laboratories, the BSMI supports 4 million testing services across various industries, generating an estimated NT$20 billion in testing output value.

In addition, the BSMI continues to develop advanced applications on calibration and measurement technologies. Key achievements include:

1.Nanoscale Measurement Technology

New advances in nanoscale metrology are helping the semiconductor industry achieve tighter control over critical dimensions (CD), boost chip performance, ensure material purity, and raise overall production yields.

2.Self-Calibrating Temperature Sensors for Industrial Equipment

A new generation of self-calibrating temperature sensors now enables online calibration without dismantling equipment, cutting calibration time from 12 days to just 30 minutes. Meanwhile, the Digital Linear Guide Adjustment Technology reduces the assembly and alignment time for machine tool linear guides from 90 minutes to 30 minutes.

3.Acoustic-AI Inspection for Wind Turbines

An integrated acoustic and AI system now allows wind turbine blades to be inspected without shutting down operations. Inspection time has dropped from 30 minutes to 5 minutes, with accuracy surpassing 90%, significantly lowering operation and maintenance (O&M) costs.

4.Domestic Calibration for Railway Boundary Measuring Instruments

A new locally developed calibration capability for railway boundary measuring instruments is significantly reducing both turnaround time and associated costs.

The BSMI emphasized its commitment to not only maintaining the alignment of national standards with international benchmarks but also continuing to develop forward-looking measurement technologies. By providing a foundation of precision measurement to support scientific and technological progress, the BSMI aims to build a reliable and secure living environment for the public.
