ASTM D619-99 - 10.10.1999
 
1. Scope

1.1 These test methods cover the procedures for testing vulcanized fibre (Note 1)) sheets, tubes, and rods of such grades as can be used for electrical insulation.

Note 1-The variant spelling "fibre" as an industry accepted practice has been approved by Committee D-9 for use in these test methods.

1.2 The procedures appear in the following sections:

Procedure Section Arc resistance 23 Ash 6 Bond strength (ply adhesion) 16 Bursting strength 14 Compressive strength 12, 25, 30 Conditioning 4 Density 17, 26, 32 Dielectric strength 18, 27 Dimensional measurements 28, 33 Flammability 22 Flexural strength 13, 31 Silica 7 Tearing strength 11 Tensile strength 10, 24, 29 Thickness (sheets) 20 Resistance to impact 15 Rockwell hardness 19 Volatile matter 8 Water absorption 5 Zinc chloride 9
