1. Scope 5. Apparatus
1.1 This practice covers a procedure for the preparation of 5.1 Panel—A supporting metal panel on which the bitumi-
accelerated and outdoor weathering test panels of bituminous nous coating is applied. It shall meet the following require-
coatings. It is considered suitable for the preparation of film ments:
