Part of the suppliers of the direct materials we use in production ( semiconductor business) are not ISO TS certified but only ISO 9001.
However we have a plan to audit them on their premises on their quality system management and control for the product ( chemicals) we purchase.
We do not have specific requirement for this products: we can say that we buy them as "standard".
Each three-four months we have meeting as well as conference call where production data are shown by the suppliers ( I mean data on the SPC, issue in case of out of spec and so on...).
To be said we also try to develop them toward a sort of compliance to ISO TS according to the 7.4.1 of ISO TS standard: I mean usage of 8D for problem solving, a sort of risk assessment on their production process ( FMEA), specification issue to react to problems.
In any case they cannot do PPAP, but we have established and agreed with them a procedure for product approval: I mean that they send a sample of product, we perform test in our production line with a trial production, and if it is all ok, we approve them as suppliers and purchase the product.
We also establish guidelines just in case they modify something in their production line that could affect the quality of product we purchase.
The question is : is it ok to comply with ISO TS or should we force and carry them to sign off a regulars PPAP according to AIAG Blue book?
