Product inquiry  

For decades, the German mining standard DIN 23311 has, first and foremost, regulated dimensions and properties of knee-protectors in respect of continuous use and rate of wear.
With the implementation of the EU Directive 89/686/EWG, knee-protectors are, by definition, Personal Protection Equipment in Category II and have to undergo prototype testing.
The European standard for knee-protectors (DIN EN 14404) has only been in existence since February 2005 but is now the basis for the quality standard testing which is obligatory for all knee-protectors distributed in Europe.

Our knee-protectors are tested and certified in accordance with the regulations of DIN EN 14404.

Amongst others, the following points are tested in the complex certification procedure:

  1. Pressure distribution, measured using a
  2. mechanical test-knee
  3. Impact resistance
  4. Penetration resistance
  5. Comfort
  6. Elasticity and width of straps

This is our quality benchmark.
