Article Abstract

Differences between ISO 9000 and QS-9000 are significant for the chemical and process industries (CPI). QS-9000 covers ISO 9001 clauses 4.1 through 4.20 plus other requirements. These additional items can produce greater benefits for the CPI, by requiring activities like benchmarking, long-term business planning, and measuring of customer satisfaction and dissatisfaction. QS-9000 specifies both the what and how of activities, and so it is more prescriptive than ISO 9000. The greatest impact of QS-9000 on the CPI may be in quality planning, APQP (advanced product quality planning), design control, PPAP (production part approval process), process control, receiving inspection, and statistical techniques. QS-9000 expects greater (compared to ISO 9000) involvement of customers in planning and APQP. HAZOP (hazard and operability) analysis is inadequate for QS-9000; potential FMEAs (failure mode and effects analyses) are required. Design control is covered by QS-9000 even if design operations take place at a nonmanufacturing site. The PPAP manual is part of the QS-9000 design requirements. Process control under QS-9000 has greater requirements than ISO 9000 for maintenance of equipment. Cpk values must be greater than 1.33. In receiving inspection and testing, the usual CPI certificate of analysis process is inadequate for QS-9000. Also required is understanding of statistical capability, stability, variation, and 14 measures and methodologies.
