Process steps

An approved quotation is the beginning of a tested and an approved product. The most important steps are:

- Initial product assessment: the assessment to determine if all requirements in the approval requirement are met.

- The result is a certificate upon which is mentioned to which requirements the product complies.

- Product verification: the assessment performed after granting certification to determine that the certified products still comply with the requirements in the approval requirement. 

- Control on quality system requirements: control on following the IQC scheme (as described in the approval requirement) and the procedures.
