6 Organization of verification of purchased products

6.1 The main tasks of the personnel performing product verification are:

Verification of purchased products, as well as execution of documents and records based on the results of verification;

Checking the availability of accompanying documentation for products, certifying its quality and completeness;

Timely issuance of permits for launching products into production based on the results of verification;

Periodic control over compliance by warehouse workers with the rules for storing and issuing products to production;

Informing departments about the quality of purchased products;

Notification of suppliers about the shortcomings and inconsistencies of products identified during verification, in the process of production and operation; calling, if necessary, representatives of suppliers to participate in the acceptance and preparation of acts on non-conformity of products;

Accumulation of statistical data on the level (dynamics) of the quality of products received from suppliers.

6.2 Verification of purchased products should be carried out in a specially designated place equipped with all necessary measuring, control and testing equipment, provided with measurement, control or testing methods for products, as well as the necessary RD for products.

6.3 The conditions under which verification should be performed should be specified.
