Test MethodsWall BaseStaining of Adjacent Surfaces Induced byWall Base12.1 ScopeThis test method describes a technique forproducing a stain or di
47、scoloration that wall base may causewhen in contact with a light-colored surface, when exposed toelevated temperature aging under controlled conditions.12.2 Significance and UseWall base often is required tobe in contact with light-colored surfaces. In such applications,the discoloration or stain of
48、 the light-colored surfaces isobjectionable. This test method provides a way to evaluate wallbase for its staining characteristics.12.3 Apparatus:12.3.1 Circulating-Air Oven, capable of maintaining a tem-perature of 158 6 1.8F (70 6 1C).12.4 MaterialsMetal panels 2 in.
