Full Description

1.1 This practice describes a procedure for specimen preparation and mounting when testing reflective insulation, radiant barrier and vinyl stretch ceiling materials to assess flame spread and smoke development as surface burning characteristics using Test Method E84.

1.2 This practice is for reflective insulation materials and radiant barrier materials intended for mechanical fastening to substrates or building structural members, or intended to be mounted to a substrate with an adhesive.

1.3 Specimens of reflective insulation materials and radiant barrier materials intended for mechanical fastening shall be prepared and mounted in accordance with 6.1. Specimens of reflective insulation materials and radiant barrier materials intended to be mounted to a substrate with an adhesive shall be prepared and mounted in accordance with 6.2. If the reflective insulation material or sheet radiant barrier material includes manufacturer recommended installation instructions with the option to be installed either by mechanical attachment or adhered, the insulation material shall be tested by both mounting procedures as outlined in 6.1 and 6.2.
