We understand that the fire rating is extremely important to all our clients, and can confirm the following:
Aluminium in Building:
Aluminium alloy components used in building complies as follows. As defined by BS 476: Part 4 and the 1974 SOLAS Convention (as amended) aluminium alloys are ‘non-combustible’ and provide Class 1 surface spread of flame to BS 476: Part 7. In addition, BS 476: Part 3 covers external fire exposure roof tests and the classifications laid down in the standard range from AA to DD. The first letter refers to the fire penetration performance and the second letter to the surface spread of flame. Aluminium and its alloys are rated AA, the highest possible under this classification system. Materials are also tested for fire propagation performance to BS 476: Part 6 (1989) and coating systems are considered. Aluminium achieves excellent ratings under this Standard.
Qualicoat Powder Coat Process 1. BS476
British Standard 476 refers to fire tests on building materials and structures. The parts of this standard that are of most relevance to powder coatings are Parts 6 and 7.
Part 6 - Fire Propagation
The result of this test is a fire propagation index. It is a measure of the contribution to fire growth made by an essentially flat surface. The results of the test are specific to the test specimen i.e. the product on that substrate in the form in which it was tested. Therefore, it cannot be used as a method for assessing the product in all situations.
Part 7 - Surface Spread of Flame
This is a method of measuring flame spread along the surface of a specimen. Again, the results of the test are specific to the test specimen i.e. the product on that particular substrate in the form in which it was tested. Therefore, it cannot be used as a method for assessing the product in all situations.
As defined in the UK Building Regulations 2000 - Fire Safety Approved Document B, the highest product performance classification for wall or ceiling linings is Class 0. This is achieved if a material; (a) Achieves a class 1 rating in BS476 Part 7, and (b) Achieves a fire propagation index of not more than 12 and subindex of not more than 6 in BS476 Part 6.
Our special coatings have been tested to BS476 Parts 6 and 7 and have met the criteria for Class 0 building regulation approval.
Quaicoat Powder Coat Process 1. BS476 - London Underground Approval
Approval for use in London Underground is a good indicator of fire safety. The product must be tested for:
Ali-Deck Slip Resistant Inserts are made from PVC Polymers, they are generally referred to as “Self-Extinguishing” which means that they will burn whilst a high enough heat source of flame is applied to them but once removed they stop burning.
