IEC 60068-2-75 Test Eha 2J 5J 10J 20J Striking Element Electromagnet Release Impact Test Apparatus
Application:
It is used for the impact resistance test of the enclosures of household and similar electronic and electrical products and their accessories, luminaires, etc., to assess the safety performance and strength level of the products.
Samples and Restrictions:
Enclosures of household and similar electronic and electrical products, luminaires
Standards & Clauses:
IEC60068-2-75:2014 “Environment testing for electric and electronic products Part2: Test methods -Test Eh: Hammer tests IDT”
IEC60598-1:2017 “Luminaries-Part1: General requirements and tests”
IEC62262:2002 “Degrees of protection provided by enclosures for electrical equipment against external mechanical impacts (IK code) ”
Test Principle:
Test Eha:Pendulum Hammer, the striking element is free released at a certain height through a 1 m pendulum tube,impact the specimen at the lowest point in the vertical direction, after the conversion of gravitational potential energy to kinetic energy, to achieve the purpose of impact test on the sample.
Structure:
Cantilever frame,electric lift, the striking element is released by the electromagnet, fix the striking element to the height of fall through the conduit, the impact point is adjusted by XY axis movement.
