ISO 5658-2, IMO Resolution A.653(16), ASTM E 1317, ASTM E 1321

This instrument uses a gas-fired radiant heat panel with pilot flame ignition to ignite a test specimen. Following ignition, any flame front which develops is noted and a record is made of the progression of the flame front horizontally along the length of the specimen in terms of the time it takes to travel to various distances.

The results are expressed in terms of the flame spread distance/time history, the flame front velocity versus heat flux, the critical heat flux at extinguishment and the average heat for sustained burning.
To meet the IMO specification a stack is fitted complete with thermopile for estimating heat release rate.

The apparatus is supplied with all necessary controls, flux meter and specimen holder.

ASTM E 162 - ASTM D 3675

The Radiant Panel Flame Spread Apparatus measures the surface flammability of building products (ASTM E 162) and cellular plastics (ASTM D 3675) by using a gas-fired radiant heat panel.

The test result is an index that is determined from the flame spread and heat evolution factors. This index is required in various specifications especially for the mass transit industry (buses and trains).

The FTT Radiant Panel Flame Spread Apparatus is supplied as a complete easy-to-use system. Features include:

  • Porous cement and cast iron gas operated radiant panel (12" x 18") with electric spark igniter and automatic safety flame out detector.
  • Pyrometer to determine the surface temperature of the radiant panel. Mounting bracket included.
Flooring Radiant Panel

EN ISO 9239-1, ASTM E 648, ASTM E 970, NFPA 253

This test method is used to measure the critical radiant flux of horizontally-mounted floor covering systems exposed to a flaming ignition source in a graded radiant heat environment, within a test chamber. It can also be used to measure this same critical radiant flux for exposed attic floor cellulose insulation.

The European Union is using this test method for fire classificaiton of flooring products, throughout European Member States.

The radiant heat is applied by means of a gas-fuelled panel, inclined at 30º, and directed at a horizontally mounted floor covering system specimen.

The radiant panel generates a radiant energy flux distribution ranging from a nominal maximum of 10.9 kW/m2 to a minimum of 1.1 kW/m2.

Burning Behaviour Of Bunched Cables

IEC 60332-3

The European Commission and The European Cable Industry (EUROPACABLE) are finalising Classification criteria for evaluating electric cables throughout Europe under the Construction Products Directive (CPD).

The Classification utilises the results obtained from traditional IEC 60332-3 test equipment fitted with heat and smoke release measurement instrumentation.

The former is calculated by continuous measurement of the oxygen consumed and carbon dioxide generated in the combustion process.

The basis of the new test protocol was developed by FTT’s Andrew Green with colleagues from SP (Sweden), ISSeP (Belgium), CESI (Italy) and Interscience (UK) as part of an EC funded FIPEC project.
Thermal/ Acoustic Insulation Flame Propagation Apparatus

FAR Part 25 Appendix F Part VI, Airbus AITM 2.0053, Boeing BSS 7365

This test method is used to evaluate the flammability and flame propagation characteristics of thermal / acoustic insulation when exposed to both a radiant heat source and flame in a test chamber.

The radiant heat is applied by means of an inclined electric panel and directed at a horizontally mounted specimen. The electric panel and pilot burner are located in a test chamber.

The sides, ends and top of the chamber are insulated with a fibrous ceramic insulation. The front side has a high temperature, draft free observation window. Below the window is a sliding platform to enable the user to easily insert either the calorimeter holding frame or specimen holding system (retaining and securing frames).The chamber temperature is monitored with a thermocouple and displayed on a programmable LCD meter.

Roofing Tests for European Roofing Products

ENV 1187 Test 1, Test 2, Test 2 & Test 4

This European Specification specifies four methods for determining the performance of roofs to external fire exposure. The four methods assess the performance of roofs under the following conditions:
Test 1 - with burning brands
Test 2 - with burning brands and wind
Test 3 - with burning brands, wind and supplementary radiant heat
Test 4 - with two stages incorporating burning brands, wind and supplementary radiant heat

The tests assess the fire spread across the external surface of the roof, the fire spread within the roof (Tests 1, 2 and 3), the fire penetration (Tests 1, 3 and 4) and the production of flaming droplets or debris falling from the underside of the roof or from the exposed surface (Tests 1, 3 and 4). Tests 2 and 3 are not applicable to geometrically irregular roofs or roof mounted appliances e.g. ventilators and roof lights.
