Efectis UK/Ireland has recently been accredited by the United Kingdom Accreditation Service (UKAS) for the international standard BS EN ISO 1182:2020.

The ISO 1182 equipment, as shown in below figure, provides a procedure for determining whether a product or a substantial component will not, or not significantly, contribute to the fire development, regardless of its end-use applications. For construction products classified as A1 or A2, according to the European classification system (EN 13501-1), a homogeneous product or a substantial component of a non-homogeneous product, must satisfy the criteria as shown below:

Criteria for A1 with regard to ISO 1182 testing:

  1. The temperature increase shall not exceed 30⁰C.
  2. The mass loss shall not exceed 50%.
  3. There shall be not sustained flaming at all.

Criteria for A2 with regard to ISO 1182 testing:

  1. The temperature increase shall not exceed 50⁰C.
  2. The mass loss shall not exceed 50%.
  3. The sustained flaming shall not continue for longer than 20 seconds.

The aforementioned procedure and the same type of apparatus is used for both US and European classification requirements; just the pass/fail criteria has been set differently in each case. In addition, the apparatus is used as well in maritime applications with different criteria set accordingly.
