Some standard content:

GB/T15481—1995
The International Organization for Standardization Committee on Conformity Assessment (ISO/CASCO) has formulated a number of guidelines on laboratory accreditation, which have been approved and issued by ISO and IEC: With the development of international trade and technical cooperation, countries attach great importance to the review, accreditation and supervision of laboratories. my country has already started the review and accreditation of laboratories. In order to standardize this work and align it with international practices, ISO/IEC Guides 25, 43 and 58 have been adopted and formulated into a series of national standards in my country, which are completely consistent with the original guidelines in terms of technical content and writing format.
This series of national standards includes:
GB/T 15481-1995 General requirements for the competence of calibration and inspection laboratories GB/T15483-1995 Development and operation of laboratory competence comparison tests GB/T15186—1995 General requirements for the operation and recognition of calibration and inspection laboratory accreditation systems This standard is equivalent to ISO/IEC Guide 25 and formulated into a national standard in my country. This standard was proposed by the State Administration of Technical Supervision. This standard is under the jurisdiction of the National Technical Committee for Quality Management and Quality Assurance. The main drafting units of this standard are: China Institute of Standardization and Information Classification and Coding, Supervision and Management Department of the State Administration of Technical Supervision, Guangzhou Electric Science Research Institute, China Electrical Equipment Testing Institute, Boiler and Pressure Vessel Testing Research Center of the Ministry of Labor. The main drafters of this standard are: Chen Zhitian, Zhou Haozhi, Gu Yanjun, Li Qiang, Jiang Hongfu, Yao Zhenzhi, Chu Fei. ISO/IEC Foreword
ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) together form a worldwide standardization system. ISO and IEC have established corresponding technical committees to deal with technical activities in specific fields, and national groups participate in the formulation of international standards through these technical committees. The technical committees of ISU and IEC cooperate in areas of mutual interest. Other international organizations that maintain contact with IS) and IEC, whether official or non-official, are also called participants in this work. At the request of the International Laboratory Accreditation Conference 1988 (ILAC 1988), the international laboratory accreditation conference held in Auckland (New Zealand) from 17 to 21 October 1988, the ISO Committee on Conformity Assessment (CASCO) has prepared this Guide, the fourth edition of ISO/IEC Guide 25. This Guide was approved by the Council of IEC in October 1990 and by the Council of ISO in December 1990. Unless consensus can be reached within a committee recognized by the Council of ISO and IEC, these documents prepared by CASCO are issued as Guides in accordance with the general rules for the preparation and publication of ISO and IEC standards. The work of ISO/CASCO in compiling Guides is the basis for third-party certification systems, which should be based, to the extent possible, on internationally recognized standards and procedures. Recognizing the primary role of the manufacturer in the declaration of conformity through the common manufacturer/customer relationship, Council resolutions have emphasized the need for guidance documents on third-party conformity assessment procedures to enable national systems to be compatible and to promote bilateral and multilateral collaboration.
These documents provide guidance, but it is expected that countries will adopt them without modification. Considering that some countries may adopt these guidelines directly, some words such as "shal1" are used in the guidelines to indicate those contents that are expected to be mandatory. The purpose of this document to provide guidance remains unchanged.
National Standard of the People's Republic of China
General requirements for the competence ofcalibration and testing laboratoriesCB/T15481—1995
Since the last revision of ISO/IEC Guide 25 in 1982, the use of quality systems in laboratories has increased significantly. Many countries use ISO/IEC Guide 25 as the basis for establishing quality systems in laboratories and recognizing their competence (e.g. through accreditation). In recent years, the field of quality assurance has developed rapidly, and a number of new and more complete guidelines and standards have been developed, and it is necessary to revise ISO/IEC Guide 25 to reflect these changes.
During this revision, the focus was on the activities of both calibration laboratories and test laboratories, and some other requirements for laboratory competence were taken into account, such as the Good Laboratory Practice (GLP) of the Organization for Economic Cooperation and Development (OFCI) and the requirements for laboratory competence in the ISO9000 series of quality assurance standards.
This standard provides a mechanism to increase confidence in calibration and test laboratories to prove that laboratory work meets common requirements. Mutual acceptance of calibration and test results between countries will help eliminate non-tariff trade barriers. The use of this standard will facilitate cooperation between laboratories and other institutions, promote the exchange of information and experience, and the coordination of standards and procedures. This standard applies to calibration laboratories and test laboratories. Laboratories that meet the requirements of this standard comply with the relevant requirements of GB/T19000-ISO9000 series standards in terms of common calibration and test activities, including the requirements of the model described in GB/T19002-ISO90002 when they provide calibration and test results as suppliers. For laboratories working in special fields, such as the chemical field (see the OECD's Good Laboratory Practice Guidelines) or the information technology field, the requirements of this standard should be supplemented and explained in accordance with GB/T 15486 General Requirements for the Operation and Recognition of Accreditation Systems for Calibration and Inspection Laboratories.
1 Scope
1.1 This standard specifies the general requirements for laboratories. If a laboratory wants to be accredited as having the ability to perform specific calibrations or inspections, it must demonstrate that its work complies with these general requirements. 1.2 In order to assess the technical competence of a laboratory or determine whether it meets other criteria, the organization or authority granting accreditation may specify some additional requirements and information to be provided based on the characteristics of the laboratory's tasks, but these additional requirements and information to be provided must be published. 1.3 This standard can be used by calibration and inspection laboratories when establishing and implementing their quality systems; it can also be used by accreditation bodies, certification bodies and other organizations related to laboratory competence. 2 Referenced standards
