Construction fire testing services

Warringtonfire’s team of engaged experts offer a wide variety of services to the construction industry, one of the ways we support this sector is through our construction fire testing capabilities.

Our laboratories in High Wycombe and Warrington are UKAS accredited, our Australian laboratory is NATA accredited, our Gent laboratory is BELAC accredited and our Frankfurt laboratory is DAkkS accredited. Frankfurt is also certified by the DIBT (Deutsches Institut für Bautechnik) as an accredited test center.

Among other things, for construction fire testing we test building materials according to national, European and International standards.

Our construction fire testing is mainly to flammability standards with some smoke density according to:

  • EN ISO 11925 Ignitability
  • EN ISO 9239-1 Radiant panel test for floorings
  •   EN 13820 organic content
  • EN 15725 and CEN/TS 15117: Extended application of test results (EXAP)

International ISO standards

Construction fire testing - Center of excellence for roof testing

There are many types of construction fire testing, fire resistance and reaction to fire tests both investigate the fire behavior of a construction element if it undergoes an attack from the inside. However, this cannot demonstrate how a roof, roof covering, or light dome reacts in the event of a fire attack from outside. These attacks can be caused by fire transfer from an adjacent burning building and / or by spread of flame from an outdoor fire.

Our laboratory in Gent is our center of excellence for roof testing. In the European classification system according to EN 13501-5, this type of construction fire testing is split into four different test methods where flame spread, and flame penetration are the basic criteria. Different additional measurements are made depending on the test method.

The four tests essentially break down to:

  • Test 1: the method with burning wood
  • Test 2: the method with burning wood and wind
  • Test 3: the method with burning wood, wind and radiation
  • Test 4: the method in two steps, with burning wood, wind and radiation 

We offer all four European roof tests (exposure to external fire), covering the whole European market for Broof classifications (test 1, test 2, test 3, test 4) as well as being able to test according to BS 476-3 for the UK market.

The specific standards we test to are:

  • CEN/TS 1187: Test methods for external fire exposure to roofs (test 1 to 4)
  • EN 13501-5 (classification): Classification using data from external fire exposure to roofs tests
  • CEN/TS 16459 (exap): Extended application of test results from CEN/TS 1187 
  • BS 476-3: Classification and method of test for external fire exposure to roofs

  There is no link or hierarchy between the different test methods. Each test is separate from the other.
