Certification and testing of helmets - resistance and strength tests

Helmets can be divided into industrial and sports helmets. Industrial protective helmets are used to protect the user's head mainly from falling objects. Sports helmets serve to protect the user's head when performing various types of sporting activities.

What is tested:

weight measurement, visual field and protected area
impact resistance
impact and breakdown resistance
the strength and efficiency of the headband attachment
buoyancy resistance
measurement of clearances, heights and other distances
resistance of chin strap fastening
flame resistance
resistance to lateral deformation

What is assessed:

accompanying documentation (drawings, etc.)
manual
marking (mandatory data marked on the helmet)

Most frequent problems:

cracked buckle
exceeding the maximum permissible value in the impact resistance test
touch the test tip with the headform
