European test standard prEN 1621-1 for impact protectors

 

Test Procedures

Measurements and classification for CE protector types (sizes) A and B, Sizes of the test templates in metric mm
S = Shoulder, E = Elbow, K = Knee, H = Hip, L = Shin

The protector size is tested with templates. The protectors are classified in type A or B. The measurements of the type B protectors are designed to meet the needs of most motorcyclists. However, in some cases, type B protectors are not appropriate for ergonomic reasons. In these cases, type A protectors provide a good alternative. The test template has to cover the entire surface of the protector.

 

The protectors are conditioned for 24 hours at a temperature of 68°F (20° Centigrade) and 65 % relative humidity. They are then removed from the climatic chamber and immediately placed on a probe with a sensor. A drop weight of 11 pounds (5 kg) above the protector is dropped three times. The sensor measures the residual energy.
