ANNEX

ANNEX

The tables set out in this Annex, list construction products and/or materials which satisfy all of the requirements for the performance characteristic ‘reaction-to-fire’ without need for testing.

Table 1

Classes of reaction to fire performance for steel sheets with polyester coating used as single skin (without insulation behind)

Product

Nominal thickness ‘t’ of metallic coated steel sheet

(mm)

Profile

Class  ( 1 )

Metallic coated steel sheet, profiled or flat, of nominal thickness t (mm) and coated on the surface exposed to the fire with a polyester coating of maximum nominal thickness 25 μm, according to the relevant part of EN 14782 and EN 10169, if the coating has a mass of no more than 70 g/m 2 and a PCS of no more than 1,0 MJ/m 2 .

The steel sheet surface not exposed to the fire may have an organic coating, provided that this coating has a thickness of no more than 15 μm and a PCS of no more than 0,7 MJ/m 2 .

0,40 ≤ t ≤ 1,50

Flat or profiled  ( 2 )

Symbol used: PCS = gross calorific potential.

(mm)

Assembly detail

Class  ( 4 )

Metallic coated steel sheet, profiled or flat, of nominal thickness t (mm) and coated on the surface exposed to the fire with a plastisol coating of maximum nominal thickness 200 μm and having a coating mass ≤ 300 g/m 2 and a PCS ≤ 7,0 MJ/m 2 .

The steel sheet surface not exposed to the fire may have an organic coating, provided that this coating has a thickness ≤ 15 μm and a PCS ≤ 0,7 MJ/m 2 .

0,55 ≤ t ≤ 1,00

Flat or profiled product used as a single skin (without insulation behind) or backed by mineral wool as part of a built up assembly (which may be a double skin). If the product is profiled, the profiled (corrugated) surface area shall be no more than twice as much as the overall (coverage) area of the product.

The mineral wool shall be of at least class A2-s1,d0. The mineral wool shall be of thickness at least 100 mm, unless the material (if any) immediately behind the mineral wool — including any vapour barrier — is of at least class A2-s1,d0.

The supporting structure shall be of at least class A2-s1,d0.

C-s3,d0

Symbol used: PCS = gross calorific potential.

( 1 )   Class as provided for in Table 1 of the Annex to Decision 2000/147/EC.

( 2 )   The profiled (corrugated) surface area shall not be more than twice as much as the overall (coverage) area of the product.

( 3 )   Tolerances on nominal thickness shall conform to the relevant standards as referenced in EN 14782 and EN 14783.

( 4 )   Class as provided for in Table 1 of the Annex to Decision 2000/147/EC.
