Generally, a test report will be marked with CMA, CNAs and cal. What do these three marks mean respectively? In order to help you have an in-depth understanding, the following contents are sorted out by Chuangxin testing network for your reference.

The three marks on the test report mean:

1、 Metrological certification mark

It indicates that the institution has passed the metrological certification of the national certification and Accreditation Administration Committee or the quality and Technical Supervision Department of the people's Government of all provinces, autonomous regions and municipalities directly under the central government.

CMA is the abbreviation of "China Metrology Accreditation"; The Chinese meaning is "China Metrology Certification". It is a comprehensive certification and evaluation of the testing ability and reliability of testing institutions by the metrological administrative department of the people's government at or above the provincial level in accordance with the provisions of the Metrology Law of the people's Republic of China. Such certification targets are all product quality supervision and inspection institutions and other laboratories that issue fair data to the society; Such as various product quality supervision and inspection stations, environmental testing stations, centers for disease prevention and control, etc. The testing organization that has obtained the metrological certification certificate is allowed to use CMA mark on the inspection report; The inspection report marked with CMA can be used for product quality evaluation, achievement and judicial appraisal, trade transactions and other aspects. It has legal effect and is the basis for arbitration and judicial institutions to accept. CMA is generally only for third-party laboratories, including a small number of specific second-party laboratories. The scope is relatively small. It is generally reviewed and approved, and it is qualified only after being authorized by the government.

The product quality inspection institution that has obtained the metrological certification certificate can use the metrological certification mark on its product inspection report according to the inspection items specified in the certificate. The mark is composed of the figure formed by three English letters of CMA and the number of the metrological certification of the inspection institution.

2、 Product quality inspection organization examination qualified symbol

It indicates that the institution has obtained the certificate of authorization for examination and approval (acceptance) from the national certification and Accreditation Administration or the quality and Technical Supervision Department of the people's Government of all provinces, autonomous regions and municipalities directly under the central government. CAL is the certification symbol of the quality supervision and inspection organization. It is the authorization mark used by the authoritative quality supervision and inspection organization granted by the national quality supervision department. It can undertake the legal quality supervision and inspection tasks issued by the national administrative organization, and can also issue the inspection report with cal and CMA marks. Before granting, the organization must pass the CMA measurement certification, otherwise it cannot be granted.

The examination qualification symbol is composed of the figure formed by the three English letters cal and the examination qualification certificate number of the inspection organization. CAL is the prefix of the corresponding English words of "China qualified laboratory".

3、 Laboratory Accreditation Mark

It indicates that the organization has passed the accreditation of China National Accreditation Committee for conformity assessment. CNAs: China National Accreditation Service for conformity assessment, "CNAs" logo indicates that the testing capacity and equipment capacity of the quality inspection center have been recognized by China National Accreditation Commission for conformity assessment. CNAs is any laboratory that can apply for accreditation. As long as you have the corresponding testing ability, you can issue certificates through accreditation, including first-party, second-party, third-party laboratories, enterprises and even personal laboratories, etc., with a wide range.

The accredited laboratory shall be granted the qualification certificate by the China National Accreditation Commission for conformity assessment, and the laboratory is allowed to use the "China National Accreditation Mark for conformity assessment" on the inspection report or calibration certificate issued by it.

Comparative analysis of three signs

Different natures: CNAs is a laboratory accreditation, which is voluntary. Of course, if it is a national laboratory, it must also pass the accreditation of CNAs; Cam is metrological certification and is mandatory.

Different functions: CNAs can realize international mutual recognition; CMA has Chinese characteristics. CNAs laboratory accreditation is an international standard, and the test report issued can be recognized internationally; Measurement certification is a domestic standard. The test report issued after measurement certification has legal effect in China. It is required that the unit doing measurement certification must have independent legal personality.
