Article 1 
A Community classification system as envisaged by Directive 89/106/EEC is hereby established in respect of the external fire performance of roofs and roof coverings.
That classification system shall be as set out in the Annex hereto.
Article 2 
This Decision is addressed to the Member States.
ANNEX
ENV 1187:2002 and subsequently upgraded versions shall be applied. The upgraded version shall include, inter alia, new revisions/amendments of the ENV or the EN version of this standard.

The classification set out in the table below is based upon the standard contained in ENV 1187:2002. That standard incorporates four distinct test methods that correspond to different fire hazard scenarios. There is no direct correlation between the test methods and hence no generally acceptable hierarchy of classification between them.

In regulating for the external fire performance of roofs/roof coverings, Member States may select the test/class combination(s) appropriate to the actual fire hazard(s) on their territory and establish a national hierarchy of classification between the various tests/classes.

Commission Decision 2000/553/EC establishes a list of roof covering products (and/or materials) which can be considered to fulfil all of the requirements for the performance characteristics ‘external fire performance’ without the need for testing, subject to any national provisions on the design and execution of works being fulfilled. Such products/materials are considered to be Classes BROOF in the table below, without the need for testing.

The classifications according to the four test methods are identified as follows:


— ENV 1187:2002 test 1: XROOF(t1), where t1 = Burning brand alone,
— ENV 1187:2002 test 2: XROOF(t2), where t2 = Burning brand + wind,
— ENV 1187:2002 test 3: XROOF(t3), where t3 = Burning brand + wind + radiation,
— ENV 1187:2002 test 4: XROOF (t4) where t4 = burning brand + wind + supplementary radiant heat.

— In the preliminary test, flame spread < 0.38 m across the region of burning
DROOF (t4) All of the following conditions must be satisfied:
— Roof system is penetrated within 30 minutes but is not penetrated in the preliminary flame test
— In the preliminary test, after withdrawal of test flame, specimens burn for < 5 minutes
— In the preliminary test, flame spread < 0.38 m across the region of burning
EROOF (t4) All of the following conditions must be satisfied:
— Roof system is penetrated within 30 minutes but is not penetrated in the preliminary flame test
— Flame spread is not controlled
FROOF (t4) No performance determined

*Attention shall be drawn to dripping from the underside of the specimen, any mechanical failure and any development of holes by adding a suffix “x” to the designation to denote that one or more of these took place during the test. In addition, depending upon inclination of the product during the test, the letters EXT.F will be added to indicate “flat or horizontal” and EXT.S will be added to indicate “inclined”.
