Test Ability
CNAS laboratory: For technology research and product development, COFON has been making continuous progress. The heading office sets up Academician and expert workstation, national testing center and CNAS testing laboratory for further guaranteeing the quality of COFON products. 100+ Test equipment supports for the analysis of the micro structures, physical properties, filtration performance and other aspects of the material to ensure the products meet IEST RP-CC001.6, EN1822-3, GB2626-2006 NIOSH, IEST RP-CC001.6, EN1822-3 and other domestic and foreign industry standards.
