Quality test

A number of tests have been developed in order to objectively test the quality and the most import of these is the test that determines the carrying strength of the tray. The tray is filled with the standard weight and subsequently hung in a test machine. In this test machine, the tray makes a reproducible fall (see image) which independently establishes if the trays meet the standard requirements. Naturally, the tray should not break. If it does, the producer in question will have to make certain adjustments in his production, otherwise he will not be allowed to sell the product under the name Normpack®.
