How to better determine which EN 13501-1 rating to apply for your product

详情

 The EN ******1 test standard measures various aspects of a product's response to fire, such as flammability, smoke generation and heat release, etc. These tests are carried out in a controlled environment using specific test methods, which vary depending on the type of product being tested.
EN ******1 applies:
There are three main categories:
*-Building products, other than flooring materials and tubular thermal insulation;
*-Flooring materials;
*-Tubular insulation.
What are the classes that can be applied for by EN ******1:
1) Testing of building products (except paving materials).
*-Grades A1 and A2, Grades B, C and D, Grades E and F;
*-Additional grades of tobacco production: S1, S2, S3; (A2, B, C and D grade products can have additional grades of s1, s2 and s3 in terms of tobacco production)
*-Additional grades D0, D1, D2 for burning droplets/particles; (Class A2, B, C, and D products may have additional grades d0, d1, and d2 in terms of their burning droplets/particles)
2) Paving material test
*- A1fl and A2 fl grades, B fl, C fl and D fl grades, E fl, F fl grades;
*-Additional grades of S1 and S2 for tobacco production; (A2fl, B fl, C fl and D fl can have additional grades s1 and s2 in terms of tobacco production)
3) Tubular insulation material test
*-A1 L and A2 L, BL, CL and DL, EL, FL;
*-Additional grades of tobacco production: S1, S2, S3; (A2L, BL, CL, DL grade products can have additional grades of s1, s2 and s3 in terms of tobacco production)
*-Additional grades D0, D1, D2 for burning droplets/particles; (A2L, BL, CL, DL grade products can have additional grades d0, d1, d2 in terms of burning droplets/particles)
 
The grading identifiers are as follows:
A*-s1,d0             A*-s1,d1　　   　  A*-s1,d2
 
Determine the material properties of the product:
The material composition, structure, density and other characteristics of the product directly affect the fire performance of the product. Depending on the characteristics of the product and its intended use, the appropriate fire rating needs to be selected. Different levels use different test methods, e.g. Class E is tested according to EN ISO ******2 and meets the requirements. The specific test content includes the combustion rate, burning time, drip resistance and whether the drop beads burn.
When applying for a fire rating, it should be noted that the European Union stipulates that all building products must have a fire rating of EN******1 E and above. Therefore, at least an E grade or higher should be applied.
