Fire Resistance |
|
| Tests were carried out on a plastered surface, the following results were obtained | |
| Fire Propagation | A propagation teat in accordance with BS 467 part 6 1968 resulted in an index performance (1) of 2.3p and a sub index (I) of 1.6 |
| Spread of Flame | Spread of flame was tested in accordance with BS 467 part 7 1971 and was found to have a class 1 surface spread of flame |
| Ignitability | Ignitability was tested in accordance with BS 467 part 5 1968 and was awarded classification 'P' -NOT easily ignitable |
