Only 70 of 270 suppliers of Proton Holdings Bhd complies with the ISO/TS 16949 automotive quality standard which ensures quality for automotive-specific suppliers. This is only about less than a third, which would explain why Proton cars seem to be sub-standard in terms of quality. Roughly 30-40 of the 270 suppliers do not posess any certification at all, while the remainder are ISO9001 certified.

Proton Holdings Bhd director of manufacturing Datuk Kamaruzaman Darus said that Proton tier-1 vendors must all obtain the ISO/TS16949 certification. There is no time frame for compliance for the moment, with Datuk Kamaruzaman choosing only to say “the sooner the better”.

Datuk Kamaruzaman Darus also said for any future new models, only certified vendors would be used, and minimum certification would be ISO9001. The Proton Vendors Association signed an MoU with UK’s Vehicle Certification Agency (VCA) which provides quality, environmental and health and safety management system certification for ISO9001, ISO14001, ISO/TS16949 and OHSAS18001 yesterday. The Memorandom of Understanding would allow the vendor association’s 140 members to obtain ISO/TS 16949 certification from VCA at a competitive price.
