BS 6143-1:1992 Guide to the economics of quality. (Process cost model).
BS 6143-2:1990 Guide to the economics of quality. (Prevention, appraisal and failure model)
However,
ISO 6143:2001 Gas analysis. Comparison methods for determining and checking the composition of calibration gas mixtures.
So either BS 6143 never became an International Standard or it has a different number.
I wondered is BS 6143 still alive and is anyone using it (past / present). If you have used BS 6143 please tell us a little about its contents uses and usefulness.
Note: The Bibliography of ISO 9004:2000 lists ISO/TR 10014:1998 Guidelines for managing the economics of quality. Maybe this is BS 6143.
Thanks,
Simon
