 CMA

CMA is short for China Metrology Accredidation. It is a mark of qualified measurement certification by a testing organization, and the organization with this mark is an inspection agency that is legal in China and authorized by the national or provincial measurement certification management department.

Institutions engaged in social-oriented testing and inspection of products in China must be reviewed by the national, provincial, and municipal metrological certification management agencies in conjunction with the review agency, and they can only engage in testing and inspection activities after they are established or authorized by law. Therefore, CMA is mandatory.

 

ILAC-MRA


ILAC-MRA is short for ILAC Mutual Recognition Arrangement. It is an international mutual recognition mark. The purpose of ILAC is to improve the acceptance of testing and calibration results issued by accredited laboratories in order to eliminate technical trade barriers and promote the establishment of international cooperation in international trade. Till to 12/12/2008, 62 laboratory accreditation bodies in 48 economies in the world have signed the ILAC mutual recognition agreement. The identification certificates with this mark can be mutually recognized internationally, and the identification results can be recognized by the United States, Japan, France, Germany, the United Kingdom and other countries.


CNAS

CNAS is short for China National Accrediation Board of Laboratories. CNAS is the symbol of national laboratory. The presence of this mark indicates that the inspection agency has passed the assessment of the China National Laboratory Certification Committee, and its inspection capabilities have reached the level of a national laboratory. According to the relevant agreements of China's accession to the WTO, the CNAS logo can be mutually recognized internationally, for example, it can be recognized by countries such as the United States, Japan, France, Germany, and the United Kingdom.


All the equipment of Pego can come with a calibration certificate issued by the labs recognized by CNAS and ILAC-MRA.

UL746A High Current ARC Ignition Test Apparatus 32.5A/COSφ0.5

UL746A High Current ARC Ignition Test Apparatus 32.5A/COSφ0.5   1.  Introduction: The high current arc ignition tes t apparatus is designed according to  IEC60950-1:2001  clause 4.7.3.6 , BS/EN60950-1:2001, BS7002:2001, GB4943-2001 and UL746A, IEC60947.1:1999, GB/T14048.1-2000, IEC730.1:1993, GB14536.1-1998 and etc..  It ’ s used to measure and assess  solid insulating material against to resistance to ignition from arcing electrical sources. A power 240V(AC)/60Hz is to be supplied to the test electrodes  (fixed electrode and movable electrode) , a series (inductive-resistive) air core impedance is to be provided to yield a short circuit current of 32.5A and a power factor of 0. 5. The sample is be to positioned with the electrodes making initial contact on the surface of the sample, the circuit is to be energized and the cyclic arcing started. The timing of arcs is to be adjusted to a rate of 40 arcs/min, the rate of electrode separation is to be 254±...
