(2) Its activities should meet the requirements of national laws and regulations, which means that the laboratory should carry out its work within the scope permitted by its legal person license.

3. The management system meeting the recognition requirements has been established and has been officially and effectively operated for more than 6 months.

The management system covers all the application scope, meets the requirements of recognition criteria and its application instructions in special fields, and has operable documents. The organizational structure is reasonable, the post responsibilities are clear, and the interface between documents at all levels is clear.

(1) Compliance means that the management system of the laboratory should meet the requirements of the basic accreditation criteria, such as CNAS-CL01, and also meet the requirements of the accreditation rules documents, such as cnas-rl02, the requirements documents and the instructions of the basic accreditation criteria in the professional application field, such as the calibration laboratory should meet the requirements of cnas-cl25, etc.

(2) Formal operation refers to the laboratory that establishes the management system for the first time. Generally, it should enter the trial operation stage first, adjust and improve the management system through internal audit and management review, and then formally operate.

(3) Effective operation means that all elements involved in the management system have been operated and relevant records have been kept.

(4) After 6 months of formal and effective operation of the management system, complete internal audit and management review covering the whole scope and all elements of the management system shall be carried out.

4. Technical capability certification materials meeting cnas-rl02 capability verification rules.

As long as there is an available capability verification, each sub field for which the laboratory applies for accreditation for the first time should have participated in at least one capability verification and obtained satisfactory results (the capability verification participated in within 3 years before the date of application for accreditation is valid).

5. Have sufficient resources to carry out testing / calibration activities within the scope of application.

(1) Personnel. There are personnel who meet the requirements of CNAs, and the number of personnel and work experience match the workload and activities of the laboratory. The main management personnel of the laboratory and all personnel engaged in testing or calibration activities shall have a long-term fixed labor relationship with the laboratory or its legal institution, and shall not engage in similar testing or calibration activities in other laboratories of the same type.

(2) Environment. The testing / calibration environment of the laboratory can continuously meet the requirements of corresponding testing standards and calibration specifications.

(3) Equipment. The laboratory has sufficient instruments and equipment and reference materials that match its business and workload, and the laboratory has full right to use the instruments and equipment.

6. The quantity traceability of instruments and equipment used shall meet the relevant requirements of CNAs.

(1) For instruments and equipment that can be traced to SI units, the calibration organization selected by the laboratory shall be able to meet the provisions of cnas-cl06 requirements for traceability of measurement results.

(2) The equipment for internal calibration shall comply with cnas-cl31 internal calibration requirements.

(3) For those that cannot be traced to SI units, it shall meet Article 5 of CNAS-CL01 accreditation criteria for the competence of testing and calibration laboratories 6. 2. 2.2 requirements.

7. The technical ability applied for approval has corresponding testing / calibration experience.

(1) The test / calibration items applied for approval by the laboratory must have corresponding test / calibration experience (the test / calibration experience does not necessarily require the test report / calibration certificate issued externally).

(2) The testing / calibration items applied for approval by the laboratory shall be the main items frequently carried out, mature and within the main business scope of the laboratory:

① Do not accept projects for which the laboratory only applies for non main business;

② The laboratory is not allowed to apply for non main test items of a certain product, such as appearance;

③ The laboratory is not allowed to apply only for sampling (sampling) ability, and the sampling (sampling) ability shall be applied for approval together with the corresponding testing ability;

④ The laboratory is not allowed to apply only for judgment standards, but also apply for approval together with the corresponding testing ability (standard);

⑤ It is not acceptable for the laboratory to apply only for the general rules of instruments and methods, and apply for approval at the same time with the corresponding sample pretreatment capacity (standard);

⑥ For the unapproved standards / specifications (including the standard approval draft), it is not accepted to apply for approval as a standard method. However, after confirmation, it can apply for approval according to the non-standard method.

Note 1: the testing / calibration capability applied by the applicant should be a frequently carried out and mature project.

Note 2: those who do not apply for the main business scope of the laboratory and only apply for the secondary work field will not be accepted in principle. Those who have applied for the main business scope but do not apply for recognition of the main items and only apply for recognition of the secondary items will not be accepted in principle.

Note 3: the applicant should have sufficient and continuous testing / calibration experience to support the ability applied for recognition. If there is no testing / calibration experience in recent two years, in principle, this ability will not be accepted. For infrequent testing / calibration activities, such as less than once a month, the applicant shall submit recent method verification and relevant quality control records at the time of approval application. For specific testing / calibration items, if the applicant cannot establish quality control measures due to too few samples received and entrusted, in principle, the ability will not be accepted.

8. The testing / calibration capability applied by the laboratory shall be within the scope of CNAs's evaluation capability.
