Describes the requirements for doping schemes of low, medium and high tautness, together with matt and glossy finishes, for aerospace purposes. Also specifies methods of producing and maintaining on aircraft fabrics taut, water-proof and air-proof surfaces and also provides methods of protecting the fabrics from the deteriorative effects of light, weather and normal service conditions.

This British Standard specifies the requirements for doping schemes of low, medium and high tautness, together with matt and glossy finishes, for aerospace purposes.

These schemes provide methods of producing and maintaining on aircraft fabrics taut, water-proof and air-proof surfaces and also provides methods of protecting the fabrics from the deteriorative effects of light, weather and normal service conditions.

Annex F gives details of requirements for type approval.
