ISO 5659-2 Smoke production

ISO 5659-2, determination of the optical density of smoke produced from a horizontally positioned test specimen subjected to a specific thermal radiation in a sealed chamber.

Areas of use

The test method measures the ability of a specific material to emit smoke in case of a fire. The test is intended primarily for use in research and development and in fire safety engineering of buildings, trains, ships, etc.


The test method is, among others, invoked by EN 45545-2 for products used on trains and IMO 2010 FTP Code part 2 (International maritime Organisation) for products used on ships.


The results from testing according to ISO 5659-2 can be used when applying for a certificate according to rules of approval in the International Code for Application of Fire Test Procedures (Resolution MSC. 307(88)). An additional test method is IMO 2010 FTP Code part 5.

 
The test method ISO 5659-2 with additional toxicity analysis (FTIR) corresponds to the IMO Resolution MSC 307 (88) Annex 1, Part 2.

The test method is also invoked by the aircraft and train industries.

Exempel of products that can be tested according to this method

The method is used when testing products which are predominantly used on ships and trains, but also on aircrafts, for example plastics, rubbers, textiles, painted surfaces, wood or other building materials

75 mm x 75 mm, Maximum thickness 25 mm
One orientating test,
one irradiance level
specimens with the dimension

Test procedure

The test is conducted in a sealed chamber. The test sample is placed horizontally and subjected to thermal radiance. When the specimen is subjected to the irradiance it starts to emit smoke which is collected in the chamber. The smokes specific optical density (transparency) is measured with a light source and a photo cell. In the case of doing the toxicity analysis, some of the produced smoke is taken out of the chamber for analysis. Analysis is performed for each of the three irradiance levels and amongst others the following substances can be detected through FTIR analysis: Carbon monoxide, Hydrochloric acid, Hydrogen bromide, Hydrogen fluoride, Hydrogen cyanide, Nitrous oxides and Sulphur dioxide.
