Is there a national equivalent to ISO/IEC 17025 as referenced in IOS/TS 16949:2002? Is there such an equivalent standard in, say, Mexico? Some of the independent calibration labs we use there are not 17025 accredited, nor do they intend to be? We will probably have to drop them, but I wanted to explore the possibilities of the "equivalent" provision stated in para. 188.8.131.52.
