Shock Test

IEC 60068 Standard

IEC 60068 is one of the standard series on environmental testing issued by the International Electrotechnical Commission. The IEC 60068 standard series provides a series of environmental test methods for electronic and electrical products to evaluate their performance and reliability under various environmental conditions. The IEC 60068 standard series consists of multiple parts, each part covering different environmental test methods and parameters. The main topic of this section is shock testing.

01 Overview

This part provides a standard procedure for determining the ability of a specimen to withstand specified severities of non-repetitive or repetitive shocks. The purpose of this test is to reveal mechanical weakness and/or degradation in specified performances, or accumulated damage or dearadation caused by shocks, and to utilize this information, together with relevant specifications, to decide whether specimens meet the requirements. In some cases, these shock tests can also be used to determine the structural integrity of specimens or as a means of quality control.

The basic specified pulse waveform is as follows:

Key (applicable for all three Figures 1 to 3)

----: Nominal pulse

——: Limits of tolerance;

D=Duration of nominal pulse;

A=Peak acceleration of nominal pulse;

T1: Min. time during which the pulse shall be monitored for shocks produced using a conventional shock-testing machine

T2: Min. time during which the pulse shall be monitored for shocks produced using a vibration generator.

02 KRD11 Pneumatic Vertical Shock Test System

KRD11 is a fully automatic pneumatic lifting vertical shock test system. It is vertical shock test equipment with novel design, high degree of automation, simple operation and convenient maintenance. Pneumatic drive, simple structure and high reliability. Full pneumatic drive shock, clean and environmentally friendly, simple structure and high reliability.

It is used to measure and determine the impact resistance of products or packaging, and assess the functional reliability and structural integrity of the test product in a shock environment. This system can perform various conventional classic shock tests to realize the shock wave and shock energy that the product is subjected to in the actual environment, thereby improving the system or optimizing the structure of the product.

The half-sine wave generator is mainly made of engineering rubber (considering the stiffness and cohesive force of rubber) and felt pads of various thicknesses. Optional post-peak sawtooth and trapezoidal wave generator.

03 KRD12 Pneumatic Horizontal Shock Test System

KRD12 series shock test system is used to measure and determine the horizontal shock resistance of a product or package, and to evaluate the reliability and structural integrity of the test unit in a horizontal shock environment. The system can perform half-sine wave, post-peak sawtooth wave, or trapezoid wave shock test to realize the shock energy that the product is subjected to in the actual environment, thereby improving the product or packaging structure.
