2009-05-15

 

1. Any foreign businessman who sells the instruments of measurement listed in the Catalogue of Pattern Examination of the People's Republic of China for Imported Instruments of Measurement in China must apply to the AQSIQ for Pattern approval. Therefore, Pattern approval of imported measuring instruments shall be applied by the foreign businessman or his/her agent. The certificate obtained is valid for products of the foreign businessman but invalid for those who sell them.

 

2. Imported measuring instruments refer to measuring instruments produced in a foreign country or region or in Hong Kong, Macao and Taiwan.

 

3. Imported measuring instruments shall adopt the legal units of measurement.

 

4. Manufacturers shall apply for Pattern approval according to the product series. The principle of classifying product series is: products with the same principle and minor changes of structure are classified into the same product series.

 

5. The foreign businessman or his/her agent shall provide samples of measuring instruments and the following technical documents to the technical organization in charge of the Pattern evaluation:

   (1) Technical instruction of the measuring instruments;

   (2) General assembly drawings, the circuit diagram and where necessary, drawings of important constructional details;

   (3) Documentary technical standard and examination method;

   (4) Test report for the samples of measuring instrument; and

   (5) Operation manual.

   In case the foreign businessman cannot provide relevant technical documents for the purpose of confidentiality, corresponding experiment shall be

   conducted according to the general technical specifications. However, in this way, features of specific products may not be considered. Therefore, all the

   adverse consequences caused by such experiment shall be undertaken by the enterprise, and no responsibility shall be undertaken by Chinese

   government or relevant departments of China. 

 

6. The amount of samples of measuring instruments of the same serials for Pattern evaluation, in principle, is one third specifications of the serials, and three samples per specification thereof; for large or expensive products, 1 to 2 samples of measuring instruments shall be provided. The product specifications which have been chosen shall be typical, such as those with high accuracy or large measuring range, etc. Should all the samples be found qualified, products of the same serials can be regarded as qualified. However, in case some specifications are unqualified, products of the same serials cannot be regarded as qualified. Should it be found that the sample has one or several defects, and that there be sufficient and justifiable reason for rejecting the Patternthereof, the experiment will cease. For the products found unqualified in the first-time test, experiment can be applied again after the manufacturer improves the products. Samples of measuring instruments for Pattern evaluation shall be provided by the foreign businessman or his/her agent. In addition, the samples shall be returned to the applicant after evaluation.

 

7. The Pattern evaluation shall be conducted in accordance with the program of Pattern evaluation. The program of Pattern evaluation shall be formulated by the technical organization responsible for the Pattern evaluation in accordance with relevant national metrological verification regulations, technical norm of measurement or international proposal of OIML. In the event that there are provisions on Pattern evaluation prescribed in the national metrological verification regulations for those products, the execution must carried out in accordance with those provisions, and it need not draw up the program of evaluation. Should there be no relevant national metrological verification regulations, technical norm of measurement or international proposal for those products, the program of evaluation can be formulated according to relevant requirements of the contract or technical standards of the instruments. In addition, products must meet relevant compulsory requirements prescribed by the State. Meanwhile, recommendation standards also can be the references for formulating the program of Pattern evaluation. Pattern evaluation mainly involves inspection of the exterior, assessment of measurement functions, safety, adaptability to environment, reliability or test of service life, etc. 

 

8. For those instruments for which China is incapable of carrying out the Pattern evaluation or the application items are too many, the Pattern evaluation can be carried out at the work sites of the foreign businessmen. The on-spot test shall be controlled strictly.

 

9. Fees shall be charged for Pattern approval in accordance with relevant provisions prescribed by the State.

 

10. Pattern approval is different from the system certification; therefore, the replacement is not available. The certification of ISO9000 Standards is part of the system certification, and is the voluntary certification of quality system for an enterprise; while the Pattern approval is the institutionalized administration conducted by the competent metrological department. It evaluate whether the Pattern (principles, structure, accuracy, and other technical standards) of the products can meet the legal requirements for measurement or not. Therefore, they are actually different. 

 

11. The AQSIQ may, according to changes of circumstances, make minor amendments to the Catalogue of Pattern Examination of the People's Republic of China for Imported Instruments of Measurement.
