Procedure for obtaining a quality declaration

Initial investigation

The initial investigation will take place on the basis of the (product) requirements, including determination methods, stated in this Evaluation Guideline and, depending on the nature of the product to be certified, includes:

• type testing to determine whether the products meet the product and/or performance requirements;

• the assessment of the production process;

• the assessment of the quality system and the IQC scheme;

• an assessment for the presence and the functioning of the other required procedures.

Certificate issuing

After completion of the initial investigation the results are presented to the decision maker. This person assesses the results and determines whether the certificate can be issued or that additional data and/or tests are necessary before the certificate can be issued.
