Thermal Shock Testing

Shock Testing

Shock testing of products and materials determines to what degree items can physically and functionally withstand relatively infrequent, short time, moderately high-level force impulses or temperature changes that would be encountered in handling, transportation, and service environments. Vibration testing, on the other hand, determines the extent to which items can withstand mechanical vibrations.

Liquid to Liquid Thermal Shock

National Technical Systems

Liquid to liquid thermal shock testing applies thermal shocks to test samples by alternately immersing them in a high- and low-temperature liquid medium. Very high thermal ramp rates can be achieved with this method; much more so than air to air thermal shock methods.

Lightweight Hammershock Testing

National Technical Systems

Lightweight Shock Machine (LWSM) Testing per MIL-DTL-901E is the military specification covering shock test requirements for shipboard machinery, equipment, systems and structures. Anyone who produces an item for military use in any of these shipboard categories will likely need to complete this testing. The purpose of this testing is to verify the ability of shipboard installations to withstand shock loadings which may be incurred during wartime service due to the effects of conventional or nuclear weapons. These requirements grew out of the Navy’s experiences during World War II and the subsequent underwater explosion (UNDEX) experiments. In many cases, it was found that critical ship systems could be disabled by the shock effects of nearby weapons explosions that were not a direct hit on the ship itself.

Mechanical Shock Testing

National Technical Systems

The ability of a product to withstand mechanical shocks is both a key design consideration and an important selling point for certain types of military and consumer goods. For this reason, a dynamic mechanical analysis is a required component of quality control and product testing.

Pyrotechnic Shock Testing

National Technical Systems

Pyroshock testing is an important part of the design and certification processes for military contractors, aerospace manufacturers and other organizations. To meet these requirements, NTS offers a variety of pyroshock testing services.

Shipboard Shock

National Technical Systems

Equipment on naval surface ships and submarines experiences many different types of shock. Aircraft launch mechanisms, steam catapults, tail-hook arresting cables and missile launchers generate various types of shocks, as do many combat situations, such as a direct hit by enemy ordnance.
