Ensuring purchased product conforms to specified requirements

Ensuring purchased product conforms to specified requirements (4.6.1.1) 

The standard does not define what the specified requirements are in this case. Elsewhere in the standard the term seems to relate to customer requirements but when purchasing you may well not be passing on customer requirements to your supplier. In cases other than when truly subcontracting work, you will in all probability be deriving your own requirements. 

The standard requires suppliers to purchase products, materials, or services from approved subcontractors where specified bp the contract 

Notwithstanding the guidance given below under Evaluation and selection of subcontractors, this requirement does not relieve you of the responsibility for ensuring the quality of subcontracted parts, materials, and services. Therefore, it would be unwise to place orders on a customer-specified subcontractor without first going through your evaluation and selection process. You can obviously take some short cuts but don t make assumptions. The customer will not be sympathetic when you are late on delivery or your price escalates. If you find a subcontractor that can meet all your product/service requirements at a lower price you can submit details to your customer for approval.
