1.1 This guide covers the determination of the hairiness of most filament and spun yarn using a photo-electric sensor apparatus. It is not intended for use on novelty yarns. 1.2 This guide shows the values in SI units. “SI units” is the technically correct name for a system ofmetric units known as the International System […]

1.1 This practice covers procedures to perform nondestruc-tive quality control testing described in Practice D 4437 and D 4545 for evaluating the continuity of all types of geomem-brane seams using the bubble emission or vacuum chamber method. 1.2 The technique described in this practice is intended for use on geomembrane seams, patches, and defects.

1.1 These test methods deal with the measurement ofoptical properties important to automatic equipment used by the United States Postal Service, such as optical character recog-nition (OCR) readers and barcode readers. These test methods can be used to examine finished mailpieces bearing address information, as well as the unconverted materials intended to be subsequently used

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.
