EN13859-1 EU CE certification

Descripción del producto

EN ******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 EN******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 EN******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 **5/***1/EU) and its relevant standards (EN ******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 EN******1:
Fire rating: The rating is determined by testing according to EN ******1.
Water permeability resistance: There are different test standards for different levels, such as W1 level complies with EN ***8, and W2 level complies with EN ****1.
Water vapor transmission performance: Meets the declared value, and the test standards are EN ***1 and ISO ****2.
Tensile performance: Meets the declared value, and the test is based on EN ******1.
Tear resistance: Meets the declared value, tested according to EN ******1.
Dimensional stability: Does not exceed the declared value, tested according to EN ***7.
Low temperature flexibility: Does not exceed the declared value, tested according to EN ***9.
Aging test: Must meet the declared value, and is carried out according to EN ******1.
Air permeability resistance: The actual value is obtained by testing according to EN ******2.
Water tightness: measured value according to EN ***8.
Radiation resistance: measured value according to EN ****6.
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
