ISO 28594:2017 pdf free.Combined accept-zero sampling systems and process control procedures for product acceptance
ISO 28594, when referenced in the contract or product specifications, requires the supplier to perform sampling inspection in accordance with 4.2 and the product specification. However,it is recognized that sampling inspection alone does not control or improve quality. Product quality comes from proper product and process design and process control activities. When such activities are effective, sampling inspection is a redundant effort and an unnecessary cost. Suppliers that have an acceptable quality management system and proven process controls on specific processes are encouraged to consider submitting alternative acceptance methods for one or more contractually specified characteristics. In addition, suppliers that have a successful quality management system,and a history of successful process controls relevant to the products/services being procured in this contract, are encouraged to consider submitting a systemic alternative acceptance method for all the contractual sampling inspection requirements associated with 4.2.
Such submissions shall describe the alternative acceptance methods, the sampling inspection provision to be replaced, and an evaluation of the protection provided by the alternative methods as compared with the inspection requirement to be replaced. The alternative acceptance method shall include evidence of process control and capability during production, together with adequate criteria,measurement and evaluation procedures to maintain control of the process. The acceptability of the alternative acceptance methods is dependent upon the existence of a quality management system, the demonstration of its process focus, and the availability of objective evidence of effectiveness (see 5.2).
There are two ways to submit alternative acceptance methods:
a) submission of individual alternative acceptance methods for one or more contractually specified sampling inspection requirements to the customer or the customer’s representative, as specified in the contract, for approval at any time during the contract period of performance; or
b) submission of a systemic alternative acceptance method to the customer or the customer’s representative, as specified in the contract, either prior to or after award of contract. Approval prior to contract award allows the supplier to adopt alternative acceptance methods throughout the length of the contract.ISO 28594 pdf download.
