Armor certification standards

Post by WingAdmin » Sun Jun 30, 2019 11:04 am



I came across this information in the latest Rider Magazine, and it's something I had always wondered about.

All riding gear armor is not the same. The type and certification of the armor will tell you just how much protection it will give you.

To qualify for certification, a 5 kg (10 lb) weight is dropped with the force of 50 joules (approximately 37 lb-ft).

To calculate work, you multiply mass by gravity by height. So in this case (with gravity being 9.8 m/s^2):

5 kg * 9.8 * H = 50 joules

This works out to H = 1m (3 feet). So you take a 10 lb weight, drop it 3 feet onto the armor, and measure the energy transmitted. This test is repeated 9 times, and the results averaged.

There are three standards in use:

EN1621-1:2012 (armor for limbs, hips and shoulders)
- Level 1: Average transmitted force of < 35 kN, no single impact > 50 kN
- Level 2: Average transmitted force of < 20 kN, no single impact > 30 kN

EN1621-2:2014 (armor for back)
- Level 1: Average transmitted force of < 18 kN, no single impact > 24 kN
- Level 2: Average transmitted force of < 9 kN, no single impact > 12 kN

EN1621-3:2017 (armor for chest)
- Level 1: Average transmitted force of < 18 kN, no single impact > 24 kN
- Level 2: Average transmitted force of < 9 kN, no single impact > 15 kN

Some armor performs differently at different temperatures, so some manufacturers certify their armor for either extreme heat or cold.

Here's how to know just what kind of armor your protective riding gear contains:
