United States14. Sampling4.1 The material shall be
14、sampled and the properties enumerated in this specification shall be determined in accordance withthe following ASTM methods:4.1.1 The specimens shall be placed only in a clean and dry glass container sealed with a screw cap fitted with a polyethyleneliner. Rubber, cork, or coated paper closures or
15、liners shall not be used. Special care shall be taken to avoid contact with iron, dirtor moisture. Sampling shall be carried out in accordance with Practice D3852.5. Supplementary Requirements (Non-Mandatory)5.1 The following supplementary requirement shall apply only when specified by the purchaser
16、 in the purchase order orcontract:Property Specification ASTM Test MethodMolten color A D1686_A Refined phenol as produced is essentially colorless. Depending upon both the nature and duration of subsequent handling, it may discolor.Therefore, a rigid specificationfor color is impractical and for ma
17、ny uses it may be unnecessary. In those cases where such a specification is required, its magnitude will vary widely with the intendedusage. It is further recommended that the directives of Practice D3852 be strictly followed in any case where color is important.6. Keywords6.1 phenolSUMMARY OF CHANG
