IEC60068-2-75 Environmental testing – Part 2: Tests – Test Eh: Hammer tests, IEC60068-2-63, IEC62262 Degrees of protection provided by enclosures for electrical equipment against external mechanical impacts (IK code), IEC60439-5 Low-voltage switchgear and controlgear assemblies – Part 5: Particular requirements for assemblies for power distribution in public networks
This series of IK code striking elements are manufactured in accordance with the standard requirement of IEC60068-2-75 chat1and chat 2. When the striking element is released in a height, the corresponding impact energy can be produced. It can be used for the Oscillating impact test with the pendulum.
Impact hammer are used to check the durability of enclosures for electrical appliances or other electronic products. If damage occurs from the impact hammer test, accessibility probe can be used to measure the extent or severity of the damage. The impact hammer simulates the mechanical impact to which electrical equipment may be subjected.
The instrument is designed to confirm to IEC60068-2-75 and other commonly used standards in the market. All components are made to the specifications required by the standards. Hammers are available in single force selections or a universal spring hammer that offers five selectable impact energies. Each hammer is delivered in a protective case with a calibration certificate.
Body (includes release mechanism and striking element guide) mass=1250g±1g
Striking element with cocking knob and hammer head, polyamide face with a radius of 10mm mass=250g±1g
Hardness of hammer head=R100 (Rockwell Hardness)
Release Cone: 60g, release pressure＜10N
Striking elements for impact test
Striking elements for impact test are used to check the durability of enclosures for electrical appliances or other electronic products.
If damage occurs from the impact hammer test, accessibility probe can be used to measure the extent or severity of the damage.
