Fire testing according to EN ISO 1716

Purpose

Fire technical testing within EN ISO 1716 evaluates a building products calorific value, PCS (MJ/kg) The main field of application is classification according to Euroclass A_ca, A1, A1_fl, A1_L, A2, A1_L, A2_fl, and A2_L(designation for non-combustible products) according to the European System EN 13501-1 and EN 13501-6. Three other test methods are also used for these fire classes: EN 13823, EN ISO 9239-1 and EN ISO 1182. 

Example of products that can be tested with this method: 

• Homogenous and multi layered building products, for example insulation products of mineral wool with or without facings, fibre reinforced cement, silicate boards, sealing compounds etc. 

Within EU building products shall be CE-marked according to the Construction Product Regulation (CPR). Building products with harmonized product standards or that have an ETAG/EAD need a CE-marking to be sold within the EU. A basis for the CE-marking is a fire classification according to EN 13501-1 which for instance include the test method EN ISO 1716.

Method

Test procedure:

A small test specimen with a specified weight is combusted completely during constant volume and oxygen atmosphere inside a high-pressure calometric bomb. The combustion of the test specimen heats up water, whose temperature rise gives a measurement of calorific potential

Deliveries

After testing a test report is delivered in English with the results. The report can be used for classification which is needed to be able to CE-mark the building product.
