Where a material is required not to be capable of producing excessive quantities of smoke and toxic products or not to give rise to toxic hazards at elevated temperatures, the material shall comply with this test. The maximum specific optical density of smoke (Ds max) shall be obtained for each test. When making toxicity measurements, the sampling of fumes shall be made during the testing of the second and the third specimen at each test condition, from the geometrical centre of the chamber at the time when the maximum specific optical density of smoke is reached. The concentration of each toxic gas shall be determined as parts per million (ppm) in the chamber volume.

Application procedures
Where a product is required to have a surface with low flame-spread characteristics, the product shall comply with this test. Where the primary deck coverings are required to be not readily ignitable, they shall comply with this test. The test method involves mounting the conditioned specimen in a well-defined flux field and measuring the time of ignition, spread of flame and its final extinguishment, together with a stack thermocouple signal as an indication of heat release by the specimen during burning. The following data shall be derived from the test results : CFE, Qsb, Qt and Qp.
Performance criteria
| Bulkhead, wall and ceiling linings | Floor coverings | Primary deck coverings | |
|---|---|---|---|
| CFE (kW/m2) | ≥ 20.0 | ≥ 7.0 | ≥ 7.0 |
| Qsb (MJ/m2) | ≥ 1.5 | ≥ 0.25 | ≥ 0.25 |

* Materials and composites of normal thickness 50 mm or less shall be tested using their full thickness. For materials and composites of normal thickness greater than 50 mm, the required specimens shall be obtained by cutting away the unexposed face to reduce the thickness between 47 mm and 50 mm.
