This specification establishes requirements for purified terephthalic acid (PTA) used in the manufacturing of polymers, including the production of polyesters for fiber, filament, yarn, film, coating, bottle and resin applications. For purposes of determining conformance with this specification, an observed value or a calculated value shall be rounded off to the nearest unit in the last right-hand digit used in expressing the specification limit. This specification covers properties and sampling of the material.

This specification covers high strength, extra-high-strength, and utilities grades of concentric lay steel wire strand composed of three wires or seven wires in class A, class B, or class C zinc coatings specifically intended for use as overhead ground wires or static wires for electric transmission lines. The strand shall have a left lay with a uniform pitch of not more than 16 times the nominal diameter of the strand. The strand is preformed when the component wires are set to the helical form which they assume in the product by any means of process other than by merely laying them about the strand core. The approximate weight per unit length of strand and the minimum breaking strength of the finished strand are presented. The elongation shall be measured as the percentage increase in separation between the jaws of the testing machine from the position after application of the initial load, to the position of at initial failure in the test specimen.

This guide provides concepts necessary for understanding the term “uncertainty” when applied to a quantitative test result. Several measures of uncertainty can be applied to a given measurement result; the interpretation of some of the common forms is described. This guide describes methods for expressing test result uncertainty and relates these to standard statistical methodology. Relationships between uncertainty and concepts of precision and bias are described. This guide also presents concepts needed for a laboratory to identify and characterize components of method performance. Elements that an ASTM method can include to provide guidance to the user on estimating uncertainty for the method are described. This guide describes some of the types of data that the laboratory can use as the basis for reporting uncertainty.

This specification prescribes the general requirements for cleaning, coating, or surface modification, or combinations thereof, of metals and other conductive materials treated or processed by the electrolytic plasma process (EPP). These materials include products designated as long products, such as wire and fine wire, flat-rolled materials, fasteners, connectors, bolts, assemblies, structural materials, hardware items, and medical items.The testing methods and requirements for cleaning and coating of materials are covered by this specification, along with coating properties; surface modification/cleaning characteristics; coating weight and thickness; retests and disposition of nonconforming material; dimensions; preparation and sampling of test specimens; certification; and packaging.

This specification covers tin-coated hard-drawn copper braid and ribbon flat wire intended for electronic application. The tin shall be electroplated for the coating and shall be commercially pure. For purposes of this specification, the tin shall be considered commercially pure if the total of other elements, exclusive of copper, does not exceed 1%. This specification covers electrical resistivity requirements, permissible variations in thickness, permissible variations in width, and limiting number of test specimens for coating test.

This practice establishes the standard method of preserving waterborne oil samples from the time of collection to the time of analysis. Information is provided to ensure sample integrity and to avoid contamination and to minimize microbial degradation. This practice is for controlled field or laboratory conditions and specifies thorough preparation of equipment and precise operation. If, however, these details must be compromised in a field emergency, nonstandard simplifications that will minimize or eliminate consequent errors are recommended. This procedure requires the use of the following apparatuses: sample containers, preferably borosilicate glass (plastic and metal are not acceptable ); closures; an explosion-proof refrigerator; and shipping containers (sturdy cartons or wooden boxes). Samples may be of several types, such as tar balls, collected oil, oil-water mixtures, emulsions, and oil and water on collecting devices such as silanized glass cloth, TFE-fluorocarbon polymer, or other materials. Instructions are given for the care of samples to minimize changes due to autoxidation and microbial attack between the time of sampling and the time of testing. Services available for transportation of samples are described as well.

This specification covers tinned, round, soft, or annealed copper wire for electrical purposes. The tinned wire shall conformto the required tensile strength and elongation. Electrical resistivity shall be measured. The wire sizes shall be expressed as the diameter of the wire and shall be measured using micrometre caliper equipped with a vernier. The tin coating shall be continuous. The continuity of the wire shall be determined on representative samples taken before stranding or insulating. The continuity of tinning shall be determined by the hydrochlroic acid-sodium polysulfide test. The tin coating shall be firmly adherent to the surface of the copper. The adherence of coating on the wire shall be determined on representative samples taken before stranding or insulating. The adherence of coating shall be determined by the wrapping and immersion test.

This specification covers silver-coated copper braid and ribbon flat wire intended for electronic application. Two classes of silver-coated braid and ribbon flat copper wire are covered: Class A (annealed temper) and Class H (hard-drawn). The material shall be silver-coated flat wire of such quality and purity that the finished product shall meet the properties and characteristics prescribed in this specification. The specification covers tensile properties, electrical resistivity requirements, permissible variations in thickness, and permissible variations in width.

This specification covers nickel-coated copper braid and ribbon flat wire intended for electronic application. Two classes of nickel-coated braid and ribbon flat copper wire are covered: Class A (annealed temper) and Class H (hard-drawn). The material shall be nickel-coated flat wire of such quality and purity that the finished product shall meet the properties and characteristics prescribed in this specification. The specification covers tensile properties, electrical resistivity requirements, permissible variations in thickness, and permissible variations in width.

This specification covers a reference ethylene glycol-base test fluid to be used in providing base line data for ASTM coolant test procedures. The reference test fluid concentrate shall be prepared to conform to the requirements as to chemical composition prescribed. The materials used to prepare the reference test fluid shall meet the requirements specified. The formulated reference test fluid concentrate shall conform to the requirements for laboratory test performance prescribed.

This specification covers requirements and test methods for deformed polyethylene (PE) liner for the rehabilitation of gravity flow and nonpressure pipelines. PE material shall conform to the recommended hydrostatic design basis. The process shall involve installing a deformed liner into an existing pipeline then reforming the liner to fit tightly to the bore of the original pipeline. Requirements and test methods that shall conform to this specification include workmanship, dimensions, size, environmental stress crack resistance, tensile strength, tensile elongation, flexural modulus, conditioning, referee testing, quality control testing, marking, and packaging.
