Why Do People Wear Mountain Climbing Helmet for Climbing?

Why a mountain climbing helmet is needed when climbing? Mountain climbing helmets produced in Europe and the United States must pass the European Union CE standards. In other countries, although the government does not have corresponding mandatory regulations, due to market competition and legal considerations, all formal mountain climbing helmets have passed the CE standards in fact.

There are four standards for CE, which are briefly introduced as follows:

1. Positive impact test 

A 5 kg blunt-headed weight (with a blunt-head radius of 5 cm) falls freely from a height of 2 meters and hits the top of the mountain climbing helmet. The impact force on the neck of the dummy (made of wood) must be less than 8 kN, or must be less than 10 kN (CE standard). 1 kN is approximately equal to 100 kilograms of force (9.8 Newton=1 kg). In other words, the impact force of the dummy's neck must be less than 800 kilogram force, or must be less than 1000 kilogram force (CE standard).

2. Side impact test

Test it from the front, two sides and the back direction (top of the head). A blunt heavy object falls freely from a height of 50 cm. The impact force on the dummy's neck must be less than 8 kilonewtons, or must be less than 10 kilonewtons (CE standard).

3. Sharp object penetration test

A 3 kg cone (0.5 mm tip) freely falls from a height of 2 meters, and the mountain climbing helmet must withstand at least one such impact. The helmet is allowed to be damaged, but no sharp objects are allowed to directly touch the scalp.

4. Stability test (also called forward and backward displacement test)

10 kg weights are smashed on the mountaineering helmet from the front and the rear respectively. The helmet must still be worn on the dummy's head (record the angle of helmet movement after being smashed during the test).

Please pay attention to items 1 and 2 of the test standards, where the sensor measures the impact force on the neck. It shows that not only the mountain bicycle helmet is required to be impact-resistant, but also has the ability to absorb kinetic energy and cushion the impact, just like a power rope. The shock absorption function of the helmet is designed to minimize the impact on the wearer's cervical and spine.

Secondly, please pay attention to item 3 of the test standards. Although this is a "pass/fail" one-time test, a good mountaineering helmet can handle such shocks 10 times. Durability is particularly valuable in long-lasting mountain climbing activities or large rock wall operations.
