Share some important information about EN13859-1 EU CE certification

EN 13859-1 is a European standard, the full name is "Flexible sheets for waterproofing - Definitions and characteristics of underlays - Part 1: Underlays for discontinuous roofing", which means "Flexible sheets for waterproofing - Definitions and characteristics of underlays Part 1: Underlays for discontinuous roofing". Here is some important information about this standard, share:

Product scope applicable to EN13859-1: This standard specifies the characteristics of flexible sheets used under discontinuous roof coverings, including requirements, test methods and product conformity evaluation with the requirements of this standard.

The significance of EN13859-1 certification: In the EU market, the "CE" mark is a mandatory certification mark. For flexible sheet cushion products for waterproofing, affixing the "CE" mark not only proves that the product complies with the safety, environmental protection, hygiene and consumer protection requirements stipulated in the Construction Products Directive (CPR 305/2011/EU) and its relevant standards (EN 13859-1), but also helps the product reasonably avoid trade technical barriers, be sold freely in the European market and open up other international markets.

Main test items of EN13859-1:

Fire rating: The rating is determined by testing according to EN 13501-1.

Water permeability resistance: There are different test standards for different levels, such as W1 level complies with EN 1928, and W2 level complies with EN 13111.

Water vapor transmission performance: Meets the declared value, and the test standards are EN 1931 and ISO 12572.

Tensile performance: Meets the declared value, and the test is based on EN 12311-1.

Tear resistance: Meets the declared value, tested according to EN 12310-1.

Dimensional stability: Does not exceed the declared value, tested according to EN 1107.

Low temperature flexibility: Does not exceed the declared value, tested according to EN 1109.

Aging test: Must meet the declared value, and is carried out according to EN 13859-1.

Air permeability resistance: The actual value is obtained by testing according to EN 13859-2.

Water tightness: measured value according to EN 1928.

Radiation resistance: measured value according to EN 15976.

Hazardous substances: must comply with EU regulations.

This standard is important for ensuring the quality and performance of waterproof flexible sheet underlayments used in discontinuous roofs. If manufacturers want to bring their products to the European market, they must meet the requirements of this standard and obtain relevant certification.
