Vertical Impact Test Equipment Tests For Resistance To Impact IEC 60079-0 Figure A.3

Product Information:

Samples and restrictions: Cable entry devices for explosion-proof products, housings for explosion-proof products.

Test purpose: used to test the impact resistance of the cable entry device of explosion-proof products or the shell of explosion-proof products, and evaluate the impact resistance of the product.

Test principle: According to the test Ehc: vertical drop weight, the Φ25mm impact element with a weight of 1kg falls freely through the conduit at a certain height and hits the sample in the vertical direction. After the conversion of gravity potential energy into kinetic energy, the purpose of impact testing on the sample is achieved.

Equipment structure and features: beam-type frame, the hammer head is manually moved to the release position, the electromagnet releases the impact element, and the drop impact height is fixed through the conduit.

Technical Parameters:

Impact energy/J	Calculated according to height: E=G=mgh
Impact element	The front end is a hard hemisphere (Φ25mm±0.05mm), 1 kg
Catheter	With gap between impact element
Impact height	100-2000mm, manually adjustable
The impact height and energy selection method is as shown in Table 15.
