Oxygen Index

view product catalogue

ASTM D 2863, BS ISO 4589-2, NES 714

The Oxygen Index is, perhaps, the most economical and precise quality control test of combustible materials. Its ease of use together with high levels of precision has made this technique a primary characterising and quality control tool to the plastic and electric cable industries and it has been specified by several military and transport groups.

The technique measures the minimum percentage of oxygen in the test atmosphere that is required to marginally support combustion. Note that BS ISO 4589 supersedes BS 2782 Part 141.

The unit gives continuous digital readout of oxygen concentrations in the test atmosphere to facilitate quick settings of test concentration.

UL 1581

The UL 1581 is an internationally recognised standard test for evaluating fire safety for electric cables.

The FTT UL 1581 test for flammability of cable materials gives a preliminary indication of their suitability for a particular application.

The apparatus is supplied as a complete system incorporating all the features necessary for ease of use and safety.

It conforms to UL 1581 vertical specimen Bunsen burner tests and associated international standards.

Ignitability Apparatus

ISO 5657, BS 476; Part 13

Ignitability, defined as the capability of a material of being ignited, is one of the first properties to be manifest and should figure largely in any assessment of fire hazard.

The Ignitability Test Apparatus is manufactured to conform to ISO 5657 and BS 476; Part 13.

The Apparatus has been designed, principally for testing building materials and composites, but it is capable of testing any sample of size 165mm × 165mm and up to a maximum of 70mm thick.

The Apparatus measures the ignition characteristics of exposed surfaces of essentially flat materials and specimens.

Single-Flame Source Test

EN ISO 11925 - 2

The Euroclassification construction products directive enables various performance classes (A to F) to be established for wall and roofing products and floor-coverings.

Higher classifications are achieved from good performances in the SBI apparatus, for roofing and wall lining products, or in Flooring Radiant Panel test for flooring products. FTT make both of these apparatus.

"The Single Flame Source Test" is built in accordance with "ISO 11925-2: Reaction to fire tests for building products - Part 2: Ignitability when subjected to direct impingement of flame".

The apparatus is based on the German Kleinbrenner method for determining ignitability of building products in the vertical orientation .by direct small flame impingement under zero impressed irradiance.

FMVSS 302

FMVSS 302, ISO 3795, ASTM D5132-04

The FTT FMVSS 302 is manufactured according to the Federal Motor Vehicle Safety Standard No. 302. ISO 3795 is a technically equivalent standard used in Europe, Canada, and Japan; while ASTM D5132-04 is used in USA.

The FMVSS 302 specifies the burn resistance requirements for materials used in the occupant compartments of motor vehicles (i.e. passenger cars, multipurpose passenger vehicles, trucks and buses).

This is to reduce the deaths and injuries to motor vehicle occupants caused by vehicle fires, especially those originating in the interior of a vehicle from sources such as matches or cigarettes.

FAR Bunsen Burner Test

request for product catalogue

The FTT Federal Aviation Authority (FAA) Bunsen Burner Test Apparatus conforms to the fire test methods described in FAA Aircraft Material Fire Test Handbook for aircraft materials.

The apparatus is supplied as a complete system incorporating all the features necessary for ease of use and safety. It enables the user to test according to five Federal Aviation Regulation (FAR) test methods: -

  • Vertical Bunsen burner test for cabin and cargo compartment materials
  • 45-Degree Bunsen burner test for cargo compartment liners and waste stowage compartment materials
  • Horizontal Bunsen burner test for cabin, cargo compartment, and miscellaneous materials
  • 60-Degree Bunsen burner test for electric wire
  • Recommended procedure for the 4-ply horizontal flammability test for aircraft blankets.
Glow Wire Test

view product catalogue

IEC 60695-2-10, ASTM D6194, UL746A

The FTT Glow Wire Apparatus is designed to perform tests specified in various standards to test Resistance to Fire in Insulating parts.

The testing of electro-technical products for fire hazard is conducted by simulating as closely as possible actual effects occurring in practice.

The specimen tested is brought into contact with the glow-wire by a motor-driven sliding carriage. At the end of the prescribed time the specimen is automatically returned to the starting position.

Observations and measurement are made to evaluate the GWIT presented by the specimen during exposure to elevated temperatures.
