Motorcyclists' Protective Clothing against mechanical impact

EN 1621-1: 2012
Part 1 - Requirements and test methods for impact protectors

The principle of the EN 1621-1 test used to assess the protective qualities of armour worn on the limb joints while riding a motorcycle involves the sample being placed over a rigid metal hemispherical anvil of radius 50 mm which is connected to a rigid and massive base via a high speed force sensor. A 5 kg impactor with a flat strike face 80 mm x 40 mm is then dropped onto the sample from a height necessary to generate an impact speed of 4.47 m/s - This equates to an impact energy of 50 joules. Then during the impact the force transmitted through the sample to the anvil is measured by the high speed force transducer. The lower the force the more protective a product is considered to be. To pass the standard the mean maximum transmitted force must be below 35 kN and no single value should be over 50 kN. The standard includes additional tests to assess performance in high and low temperature environments plus after storage in humid conditions.

EN 1621-2: 2014
Part 2 - Requirements and test methods for motorcyclists back protectors

EN 1621-2: 2014 is a second part to EN 1621 written to specifically cover back and lumbar protectors. It uses similar design and test methodology to part 1 for testing of limb protectors except that the geometry of the anvil and striker are different to better simulate the way back protectors are intended to work. The standard includes additional tests to assess performance in high and low temperature environments plus after storage in humid conditions.
