/CNAS Packaging Material Testing Laboratory
CNAS Packaging Material Testing Laboratory March 14,2019.

Before putting much faith in a Chinese factory's test results it makes sense to ensure that the laboratory which conducted the tests has a China laboratory accreditation certificate.


Although many factory's have their own laboratories, few of these are independently certified so requesting testing by external testing body is a wise move in many circumstances.


These testing bodies should be accredited and you can make sure of this by requesting a copy of their China laboratory accreditation certificate.


What is a China Laboratory Accreditation Certificate?

The China laboratory accreditation certificate is a certificate issued to test laboratories in Mainland China which have been deemed to conform to the requirements of international laboratory standard ISO/IEC 17025.


The certificate is issued in two versions, one in Chinese and the other in English. Either way, the certificate is easily recognizable thanks to the prominently displayed "ilac-MRA" and "CNAS" logos.


What Information is Contained in a China Laboratory Accreditation Certificate?

China laboratory accreditation certificates are only issued by the China National Accreditation Service for Conformity Assessment (CNAS) and should be similar in appearance to the certificates above.


Who Issues a China Laboratory Accreditation Certificate?

As Mainland China's only signatory to the International Laboratory Accreditation Cooperation (ILAC) under the Mutual Recognition Arrangement (MRA), CNAS is the only authority which can issue China laboratory accreditation certificates.


International Mutual Recognition


China national accreditation system for conformity assessment has been a part of international accreditation multilateral recognition system, and is playing an important role in it.


CNAS was the accreditation body member of International Accreditation Forum (IAF) and International Laboratory Accreditation Cooperation (ILAC),as well as the member of Asia Pacific Laboratory Accreditation Cooperation (APLAC) and Pacific Accreditation Cooperation (PAC)
