What is a euroclass rating?
The Euroclass system was introduced to harmonise standards across the EU. It categorises products into one of seven reaction to fire classes ranging from A1 (non-combustible) down to F (the worst performing class in terms of combustibility), using a defined test or combination of tests.
What is en13501?
The EN 13501 is a fire safety certification to which all construction products and building elements should be classified. The classification is recorded by collecting data from a variety of fire tests.
How many classes of fire are listed in the European system of classification?
seven main
Fire reaction classes for surface coverings are divided into seven main classes: A1, A2, B, C, D, E and F. The conditions for fulfilling the requirements of a particular class can be found in the classifications standards, EN 13501-1 for surface linings, pipe insulation and floor coverings and EN 13501-6 for cables.
What is class E fire rating?
Class E consists of products that have a significant contribution to fire, and resist a flame for a short period only. Products that contribute to fire, but have a greater resistance to a flame are categorised as Class D.
What is ASTM E 84 fire rating?
The ASTM E-84 is the standard test method for assessing the surface burning characteristics of building products to explore how the material might contribute to flame spread in the event of a fire. The test reports the Flame Spread index and Smoke Developed index of the tested product.
What does Class 3 fire rating mean?
A Class C or Class 3 fire rating has a flame spread rating between 76 and 200. This rating incorporates building materials like plywood, fiberboard, and hardboard siding panels. It also includes any of the faster burning whole woods.
Is Class 1 or Class 0 better?
To Summarise: Class 1 – Protects your surface from the spread of flames. Class 0 – Protects your surface from the spread of flames AND limits the amount of heat released from the surface during a fire.
Is Class 0 still relevant?
Class 0 is still used in regulations to define the quality of facade cladding products, even while the mandatory European system on fire classification requires other, stronger specifications.
