Product Desciption
Safety helmet rigidity testing machine
Principle
The helmet is subjected to transverse compressive forces and the deformations measured
Safety helmet rigidity testing machine Function and feature:
1, According to ECE R 22.05 standard.
2, For testing the rigidity of a helmet, measure the extend of deformation after applying a certain load on a helmet.
3, PLC controlled.
Safety helmet rigidity testing machine Procedure
The helmet shall be placed transversely between two guided rigid parallel plates of nominal size 300mm*250mm , having their lower edges radiused to 10mm±0.5mm , the brim shall lie outside, but as close to the plates as possible . In the case of helmets without a brim , the lower edge of the helmet shall lie between the plates
An initial force of 30 N shall be applied perpendicular to the plates, so that the helmet is subjected to a lateral force. After 30s the distance between the plates shall be measured ( dimension x )
The force shall be increased by 100 N per minute up to 430 N , which shall be held for 30s , after which the distance between the plates shall again be measured(dimension y )
The force shall be decreased to 25N and then immediately increased to 30N , which shall be held for 30s , after which the distance between the plates shall again be measured (dimension Z)
Measurement shall be made to the nearest millimeter , and the extent of damage, if any , shall be noted. The maximum lateral deformation is the difference between dimension x and y . The residual lateral deformation is the difference between dimension x and z
