This British Standard specifies design require-ments for aircraft equipment that may come into contact with flammable fluids and vapours. It also specifies test requirements to demonstrate that the equipment meets these requirements.
The standard does not relate to potentially dangerous environments occurring as a result of leakage from goods carried on board by passengers or as part of their baggage, or cargo, which may be the subject of separate regulations.
It refers to normal and fault conditions occur-ring in categories of equipment in five types of environment.
The standard should also be read in conjunc-tion with British Standard 3C. 100: Part 0.
