Schocktests

Schocktests are a class of mechanical tests that evaluate a product’s ability to withstand sudden applications of high forces, simulating impacts, drops, or rapid decelerations that can occur during handling, transportation, or operation. In a typical test, the specimen is mounted on equipment such as a drop tower, a pneumatic hammer, or an electrodynamic shaker to apply controlled shocks. Tests may be single or multiple shocks and may use various pulse shapes, including half-sine, square, or trapezoidal profiles. Key parameters include peak acceleration measured in g, pulse duration, rise time, impulse, and the number and orientation of shocks.

Schocktests follow standardized procedures to ensure repeatability and comparability. Notable standards include IEC 60068-2-27 for shock, and various military and industry standards such as MIL-STD-883 or MIL-STD-810 used in aerospace and defense contexts. The choice of standard depends on the product, market, and expected shock environment. Test setups may also incorporate environmental conditions, such as temperature or humidity, when combined with shock exposure.

Data from Schocktests are analyzed to identify mechanical failures, including PCB fractures, solder joint cracks, component detachments, enclosure deformations, or connector damages. Results inform design improvements, packaging optimization, and reliability assessments. In electronics, Schocktests are commonly part of qualification testing to meet safety and performance requirements. In automotive, aerospace, and consumer goods, they help verify robustness of sensors, control units, and subsystems under real-world shock conditions.
