Recently,Hengtong's New Energy Materials and Electrical Experimental Center (hereafter as the center) has been assessed by the CNAS expert group and received the CNAS Laboratory Accreditation Certificate, which marks that test ability of  the Center has reached international level.

In order to improve quality inspection and supervision level, Hengtong carried out the planning and construction of the experimental center in accordance with the standard requirements of ISO 17025, successively upgraded key testing devices including aging test chamber, fully automatic cable temperature rise comprehensive test system, temperature& humidity cycling chamber，Xenon lamp weather-resistant test chamber, as well as ozone-resistant test chamber, which gradually improved the testing capacity of the center.

The scope of the center covers 9 standards and 22 test items  and it is the  second lab of Hengtong recognized by CNAS.

China National Accreditation Service for Conformity Assessment(CNAS）, is a professional national accreditation body, recognition of which indicates that the recognized lab has the technical ability with the international recognition standard to carry out the testing service.
