EN 15812 Polymer Modified Bituminous Thick Coatings for Waterproofing - Determination of Crack Bridging Capability

EUROLAB laboratory provides testing and compliance services within the scope of EN 15812 standard. The EN 15812 standard specifies two methods (method A and method B) for the determination of crack bridging properties of thick coatings with polymer modified bitumen for waterproofing. The two test methods are equally applicable.

The test result can be expressed in the following three ways:

Get the detection result before and after the impact, calculate the reduction rate of physical performance according to the formula. The result can be considered as a test result.

After the impact, get whether the flexible tube conforms to the physical performance predicted as the test result.

Take the sample with no contrast effect; make the flexible pipe color, transparency, gloss, cracks, crack extension, bubbles, small pits and other similar defects elongation, stickiness, stratification and bending or other deformation and partial dissolution etc. Evaluate via. Use the symbols specified in the table. 1 represents the degree of appearance variation.

The report will contain the following content:

  • test bases,
  • test items,
  • test conditions,
  • testing equipment,
  • Test results,
  • Other necessary instructions regarding samples such as materials; time to place in the test environment before tests; time from production to testing, etc.
