1 Technical Description of the Product
fischer FFSC Fire Stop Compound is a gypsum-based mortar material used to reinstate the fire resistance performance of floor and wall constructions where apertures for multiple services have been provided.
It is supplied as a dry material and is mixed with water to the required ratio prior to installation.
When mixed, fischer FFSC Fire Stop Compound is self-supporting in floors and walls up to a maximum of 1100mm x 1100mm. Temporary shuttering is required to support the wet weight of the compound.
2 Specification of The Intended Use In Accordance With The applicable European Assessment (EAD)
The intended use of fischer FFSC Fire Stop Compound is to reinstate the fire resistance performance of rigid wall and floor constructions penetrated by various cables and metallic pipes.
Elements of Construction for Penetration Seals
Rigid Floors: Must have a minimum thickness of 150 mm and comprise concrete, aerated concrete or masonry with a minimum density of 650 kg/m³.
Rigid Walls: Must have a minimum thickness of 150 mm and comprise concrete, aerated concrete or masonry with a minimum density of 650 kg/m³.
The supporting construction must be classified in accordance with EN 13501-2 for the required fire resistance period.
Service Penetrations
fischer FFSC Fire Stop Compound may be used to provide a penetration seal with cables, cable trays, and insulated metallic pipes (details in Annex B).
The total cross-sectional area of services (including insulation) should not exceed 60% of the penetration area.
Services in floors shall be supported at a maximum of 450mm from the exposed face.
Services in walls shall be supported at a maximum of 150mm from both faces of the wall.
Working Life
The provisions in this assessment are based on an assumed working life of 25 years, provided conditions for packaging, transport, storage, installation, use, and repair are met. These indications are for product selection guidance and not a guarantee.
Use Category
Type Z1: Intended for internal conditions with humidity equal to or higher than 85% RH, excluding temperatures below 0°C, without exposure to rain or UV.
3 Performance of The Product And References To The Methods Used For Its Assessment
| BWR | Characteristic | Assessment of characteristic |
|---|---|---|
| 2 | Safety in case of fire | Reaction to fire: See Clause 1.1 Resistance to fire: See clause 1.2 |
| 3 | Hygiene, Health and the Environment | Dangerous substances: See clause 2.1 |
| 4 | Safety and accessibility in use | Durability and serviceability: See clause 3.1 |
| 5 | Protection against noise | Airborne sound insulation: See clause 4.1 |
| 6 | Energy, Economy and Heat Retention | - |
3.1 Safety in case of fire
3.1.1 Reaction to fire
No performance assessed.
3.1.2 Resistance to fire
fischer FFSC Fire Stop Compound has been tested in accordance with EN 1366-3 and classified in accordance with EN 13501-2 (as given in Annex B).
Seals may only be penetrated by services described in Annex B; other parts or support constructions must not penetrate the seal.
The service support construction must be fixed to the building element containing the penetration seal or a suitable adjacent element. For floors, the unexposed side must not impose additional load on the seal in case of fire. Unexposed face support must be maintained for the required fire resistance period.
In floors, seals must be installed over a shutter capable of supporting the mortar's weight; the shutter should remain in place.
Cables should be insulated with minimum 45kg/m³ Rockwool Duct Wrap, minimum 25mm thick, 500mm long to the unexposed face.
Pipes should be insulated with minimum 150kg/m³ Rockwool H&V Pipe Section, minimum 50mm thick, 500mm long to the unexposed face (CI).
Pipes must be perpendicular to the seal surface.
It is assumed that compressed air systems are switched off by other means in case of fire. The function of pipe seals in pneumatic dispatch or pressurised air systems is guaranteed only when these systems are shut off.
The assessment does not cover the destruction of the seal or abutting building elements by forces from temperature changes during fire; this must be considered in piping system design.
The approval does not address risks from leakage of dangerous liquids or gases due to pipe failure.
The durability assessment does not account for the effect of substances permeating through the pipe on the seal.
Classifications relate to C/U (capped inside / un-capped outside the furnace) for insulated metallic pipes. Refer to national regulations for further information.
3.2 Health, hygiene and the environment
3.2.1 Dangerous Substances
The applicant declares that fischer FFSC Fire Stop Compound does not contain any substance of high concern regarding REACH Regulations and complies with requirements referenced at http://ec.europa.eu/enterprise/construction/cpd-ds/index.cfm.
Additional requirements applicable to products within its scope may exist based on transposed European legislation and national laws.
3.3 Safety and accessibility in use
3.3.1 Durability and serviceability
fischer FFSC Fire Stop Compound was tested according to EOTA Technical Report - TR024 for type Z1 use category. Test results demonstrate suitability for penetration seals in internal conditions with humidity equal to or higher than 85% RH, excluding temperatures below 0°C, without exposure to rain or UV.
3.4 Protection against noise
3.4.1 Airborne noise Insulation
The test results provided a single number rating of Rw (C;Ctr) = 47(-1;-3)dB.
4 Assessment And Verification Of Constancy Of Performance (AVCP) System
The AVCP system applied, according to decision 1999/454/EC, is System 1.
| Products | Intended use/s | AVCP System |
|---|---|---|
| Fire stopping and fire sealing products | For fire compartmentation and / or fire protection or fire performance | System 1 |
5 Technical Details Necessary For The Implementation of The AVCP System
Technical details for the AVCP system implementation are laid down in the control plan deposited at ETA-Danmark A/S prior to CE marking.
