The BS 3057:1958 standard describes two types of asbestos paper based on the amount of organic binder used. The second type is characterized by having higher mechanical strength and a minimum number of conducting paths. The standard specifies thicknesses ranging from 5 to 10 mils and requires a smooth surface finish.
The standard also outlines various tests to ensure the quality of the asbestos paper. These tests include measuring the thickness, substance (amount of asbestos fibers), electric strength, tensile strength, and bursting strength after aging. In addition, the standard includes tests for moisture content, freedom from conducting paths (to prevent electrical conductivity), and loss of weight on ignition.
