1.1 This test method covers the determination of benzene,toluene,ethylbenzene,the xylenes,C₉ and heavier aromatics, and total aromatics in finished motor gasoline by gas chroma- tography. 1.2 The aromatic hydrocarbons are separated without inter-ferences from other hydrocarbons in finished gasoline.Non-aromatic hydrocarbons having a boiling point greater than-n-dodecane may cause interferences with the determination of the C₉ and […]

1.1 This practice identifies emulsified petroleum products that may be used as recycling agents in recycled mixes. These materials are classified by viscosity or by low temperature penetration after aging. 1.2 This practice addresses emulsified materials designed specifically for use in recycling. The use of emulsified mate-rials for recycling shall not be limited to this

1.1 This practice describes an approach and methodology for immersion testing of geosynthetics (for example, geomem-branes used for landfill liner). 1.2 This practice does not provide for definition of the testing to be performed on the geosynthetic samples for field immersion. This practice does not address the determination of resistance of the geosynthetic to the

1.1 This guide provides a uniform system of symbols for the disclosure of care instructions on textile products such as apparel, piece goods, and household and instutional articles,hereinafter referred to as “hextile,” or “hextile product.” 1.2 This guide provides a comprehensive system of symbols to represent care insrnuctions reducing language-dependent care instructions.

1.1 This practice covers a procedure to test a biofouling resistant coating systems or antifouling systems, or both, when subjected to in situ partial immersion exposure. This enhances settlement of certain marine fouling organisms and increase the rate of possible physical deterioration.

1.1 This test method is used to evaluate and compare the ability of stretch-wrap films to contain unitized loads during shipping. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro-priate safety, health,

1.1 These test methods cover the determination ofthe purity ofpresent commercially available rubber chemical accelerators in the range from 80 to 100 % by high performance liquid chromatography (HPLC) using ultraviolet detection and exter- nal standard calculations.

1.1 This practice covers standard procedures for extraction of volatile and semi-volatile organic compounds from water using small volumes of solvents. 1.2 The compounds of interest must have a greater solubil-ity in the organic solvent than the water phase.

1.1 This test method covers a procedure for the determina-tion of moisture absorption or desorption properties in the through-the-thickness direction for single-phase Fickian solid materials in flat or curved panel form. Also covered are procedures for conditioning test coupons prior to use in other test methods; either to an essentially moisture-free state, to equilibrium in

1.1 This test method covers the determination of impact resistance of plastic sew-through buttons. 1.2 The values stated in either acceptable metric units or other units shall be regarded separately as standard. The values expressed in each system may or may not be exact equivalents: therefore, each system must be used independently ofthe other, without
