ASTM G113-09

Standard Terminology Relating to Natural and Artificial Weathering Tests of Nonmetallic Materials

SIGNIFICANCE AND USE
This terminology is not intended to supersede the requirements of similar definitions in certain other documents, but is intended to provide a listing of terms that are in current widespread usage, and their context in relation to weathering.
SCOPE
1.1 This terminology standard covers terms that relate to the durability testing of Nonmetallic Materials using natural and artificial weathering exposure techniques.
1.2 It is the intent of this terminology standard to include those weathering terms in wide use in ASTM for which standard definitions appear desirable.
