Rationale

1) Clarification of what a cross section of a material is needed. It’s currently mentioned in 8.1.1 and alluded to in 8.1.2 2) C871 Doesn’t mention how to test various insulation materials. Blanket Fibrous materials changed to Fibrous materials. Explanations on testing for Attached facings, Fabric /Tapes, Thermal Insulating Cement. Thermal Insulating Cements were added as they are mentioned how to test in C692 as a part of C795. Referenced Document to be added: ASTM C163: Practice for Mixing Thermal Insulating Cement Material
