ISO/IEC 17025 Calibration Laboratory
The accuracy of measuring instruments and equipment depends on the competence of the calibration laboratory. The calibration report issued by a competent calibration laboratory can ensure the compliance to the international requirements of metrological traceability and the confidence in the use of the calibration data. In addition, various conformity assessment bodies (testing laboratories, inspection bodies, medical laboratories, reference material producer, product certification bodies, validation and verification bodies, etc.) and GLP test facilities for compliance registration also need the calibration services provided by competent calibration laboratories to ensure the validity of their certificates and reports issued by them, such as those on the tests and inspection for accuracy and reliability.
The laboratory accreditation process is generally regarded as a method to evaluate the technical capabilities of laboratories. It is based on the requirements of ISO/IEC 17025. TAF has also developed related accreditation common requirements (Type R documents), service manuals and service program (Type A documents), technical criteria (Type T documents), supplementary information/requirements (Type J documents), guideline/report (Type G documents), fees schedule and other instructions (Type C documents), and application forms (Type B documents). Professional technical assessors from all fields of industry, government, academia, and research institute are invited to be as third-party position for accreditation of calibration laboratories to ensure the technical capabilities of the calibration laboratories which meet the requirements. Calibration laboratories accredited by TAF may use the TAF accreditation symbol on the issued calibration reports or certificates. The names and data of TAF-accredited calibration laboratories are officially posted on the TAF website and constantly updated to provide the correct information to external users in time.
Based on technical categories, TAF provides accreditation services of calibration laboratories which are including length, vibration/acoustics, mass/force, pressure/vacuum, temperature/humidity, electricity, electromagnetics, flow, chemical, time and frequency, ionizing radiation, etc.
Before applying for accreditation, laboratories should understand the test items and the domains that belong to, and select the appropriate item code in the “Calibration Field Accreditation Item Code Table (TAF-CNLA-D01)” and the relevant TAF documents, including "ISO/IEC 17025 General Requirements for Testing and Calibration Laboratory Competence (TAF-CNLA-R01)", "Accreditation Service Manual for Laboratories and Inspection Bodies (TAF-CNLA-A01)", " Fees Schedule and Method of Payment (TAF-CNLA-C02)”, and "TAF Regulations on Rights and Obligations (TAF-AR-10)", to understand the relevant TAF regulations and the application process.
