TAF Length Calibration Laboratory

Certificate of Accreditation


As a result of the growing popularity of outsourcing the manufacturing of certain components, the finished products need to be tested and measured for accuracy. These measured results must be traceable to known standards such as the National Institute of Standards and Technology (NIST) and the National Physical Laboratory (NPL). Hence, the type of equipment used and their calibration becomes very important. Leading automotive, industrial, and aerospace manufacturers are rigorously enforcing traceability not only among their sub-contractors but also along the supply chain. These developments in the manufacturing industry are acting as strong propellants of growth in the world non-contact measurement equipment market. In order to offer the Total-solution to our customer, we set up the length of calibration laboratory in 2006 and offer the calibration of profile projector and video measurement system .

This is to certify that

Dimensional Measurement Lab.

(from https://www.nml.org.tw )

The Dimensional Measurement Laboratory (DML) provides traceability of dimensional standards for domestic industry. The laboratory has established a variety of measurement systems categorized as end standard, scale, angle, and topography, used for the calibration of laser frequency and dimension related artifact standards. It provides calibration services for stabilized laser frequency, long and short gauge blocks, ring gauges, plug gauges, line scales, polygons, index tables, roundness, roughness, step height, standard tapes, theodolites, electronic distance measuring instruments, interferometers, gratings, line width, thin film, GPS receivers,etc.
The advanced research includes: femtosecond laser and poptical frequency standard, nanometer(10-9m)range measuring technigues, micrometer(10-6m)range measuring techniques, and geodetic measurement standards More, the calibration and measurement capabilities (CMCs) in Length (L) have been incorporated in BIPM’s key comparison database in February, 2004. It means DML’s capability has won international recognition.
