Test method EN ISO 1716, Fire technical testing of building products – Determination of calorific potential.

Main field of application

Classification according to Euroclass A1, A1fl, A2, and A2fl (designation for non-combustible products) according to the European System. Three other test methods are also used, see data sheet EN 13823, EN ISO 9239-1 and EN ISO 1182.

Examples 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. 

Material consumption during test

For a complete test, a minimum of one test specimen with the dimension 250 mm x 250 mm and the mass 50 g is required.



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
