Westpak is certified to conduct product/package integrity testing to help guarantee successful delivery of products worldwide by any means of transportation.

Westpak is accredited to ISO/IEC 17025-2005, one of the most rigorous standards available for a mechanical testing laboratory.

Westpak is certified to the requirements of ISO 9001-2008 for quality management, and to ISO 14001-2004 for environmental management and sustainability efforts.

Mechanical Shock Testing

Mechanical shock is distinguished from impact in that all the parameters of the event (pulse shape, peak acceleration, duration, etc.) are controlled. An impact, on the other hand, is characterized as an uncontrolled mechanical meeting of two surfaces.

The purpose of shock testing is to determine the sensitivity of a product to impact. This is normally referred to as product fragility analysis.

Impacts of a harmful nature are very common during product transportation and distribution. In fact, transportation represents the most severe mechanical environment of most products entire lifecycle. Some products are also subjected to high levels of impact in the in-use environment based on their function. Handheld calculators, children's toys, cellular telephones, and much military equipment are examples.

The reliability of most electromechanical products can be greatly enhanced by a carefully applied series of mechanical shock tests designed to identify the weakest elements of a product and fixing those weaknesses by judicious use of recognized design principles.
