DESCRIPTION
MINIMUM COMPLIANCE VALUES

EN 20811

To test a hydrostatic pressure increment of (980 ± 50) Pa/min, the following samples will be made:

  • Five samples to test the material before pre-treatment.
  • Five samples to test the seams before pre-treatment.
  • Five samples to test the material after pre-treatment with dry cleaning and/or washing.
  • Four treatments to test after pre-treatment with abrasion.
  • Four samples to test after pre-treatment with repeated flexion.
  • Four samples to test after pre-treatment with petroleum and oil.

If a sample obtains different classes on different tests, the lowest class must be the one indicated.

Water penetration resistance WpClass 1 Class 2Class 3
 Material before pre-treatment Wp ≥ 8000 PaDoes not need to be tested*Does not need to be tested*
Material after each pre-treatmentDoes not need to be tested* Wp ≥ 8000 Pa Wp ≥ 13000 Pa
Seams before pre-treatment Wp ≥ 8000 Pa Wp ≥ 8000 Pa Wp ≥ 13000 Pa

*Does not need to be tested, as the worst situation for classes 2 and 3 is after pre-treatment.

Note: several requirements must be met for each class.

EN 31092

Resistance to water vapour, Ret (EN 31092): tests the entire group of materials, except for anti-capillarity grooves and retroreflective and fluorescent bands.

Class 2 – 20 < Ret ≤ 40
Class 3 – Ret ≤ 20

*Class 1 has a limited time of use
