For each UN Hazardous Materials certificate, the case is first verified to be an authentic ZARGES product and the correct product requested by the customer. The case then undergoes an ultrasonic inspection to ensure that the thickness of all case walls is within tolerance for the order's specification. The measuring points are indicated in blue on the diagram. Once the case passes this inspection, it is labeled and delivered to the customer with appropriate documentation.
