The IK spring impact hammer is used to simulate the mechanical impacts that the test product may encounter during normal use, in order to check the ability of the test product's shell to withstand mechanical impacts. Suitable for conducting mechanical strength tests on the shells, operating rods, handles, knobs, indicator lights, signal lights, and lampshades of household and similar lighting fixtures, household appliances, electronic products, and other accessories to ensure that the tested products can withstand possible reckless operations and other accidents, and can operate safely and reliably normally.

The IK spring impact hammer meets the following standards: GB/T 2423.55 "Environmental testing for electrical and electronic products - Part 2: Test methods - Test Eh: Hammer impact test", clause 5 "Test Ehb: Spring hammer", GB/T7000.1，GB4706.1, GB2099.1, GB/T8898，IEC60068-2-75, IEC60598-1, IEC/EN61010-1, IEC60065, IEC60320-1, IEC60335-1, IEC60400, IEC/EN60601-1, IEC60519-1, IEC/EN61058-1, UL1244, EN60400, EN60730-1。

The IK level of the IK spring impact hammer is defined as IKXX, where "XX" represents the number of protection levels that the tested product shell can provide for external mechanical impact, ranging from 00 to 07. Different IK levels involve the resistance of the tested product shell to Joule measurement impact energy levels (J). IEC 62262 specifies how to install the tested object, requires ventilation conditions, the number and distribution of impact hammers, and the corresponding impact hammers for each level.

The external mechanical protection level is as follows:

LISUN Lishan offers two types of IK spring impact hammers:
Single type (one spring impact hammer for each IK level): IK01, IK02, IK03, IK04, IK05, IK06, IK07
Universal type (6 IK levels concentrated in one adjustable spring impact hammer): IK01-06
