Standard Practices for Electrical Methods for Locating Leaks in Geomembranes Covered with Water or Earthen Materials
Abstract: 4.1 Geomembranes are used as impermeable barriers to prevent liquids from leaking from landfills, ponds, and other containments. The liquids may contain contaminants that, if released, can cause damage to the environment. ... -
Standard Guide for Calibration Facility Setup for Nuclear Surface Gauges
Abstract: 5.1 To establish a proper calibration area for nuclear surface gauges. 5.2 To reduce the chance of improper calibration. Note 1: The quality of the results produced by this standard is dependent on the competence of the ... -
Standard Test Method for Determination of Trace Thiophene in Refined Benzene by Gas Chromatography and Sulfur Selective Detection
Abstract: 5.1 Accurate gas chromatographic determination of trace levels of thiophene in benzene involves special analytical problems because of the difficulties of trace level analysis. These problems arise from the low concentration ... -
Standard Test Method for Polyurethane Raw Materials: Determination of Basicity in Polyols, Expressed as Percent Nitrogen
Abstract: 5.1 This test method is suitable for quality control, as a specification test, and for research. The results are measures of batch-to-batch uniformity and are useful in estimating reactivity. 5.1.1 The percent nitrogen ... -
Standard Test Method for Distillation of Emulsified Asphalt
Abstract: 4.1 This test method can be used for quantitative determination of residue and oil distillates in emulsified asphalts for specification acceptance, service evaluation, control, and research. This test method can also be ... -
Standard Guide for Exposing and Testing Plastics that Degrade in the Environment by a Combination of Oxidation and Biodegradation
Abstract: 5.1 This guide is a sequential assembly of extant but unconnected standard tests and practices for the oxidation and biodegradation of plastics, which will permit the comparison and ranking of the overall rate of environmental ... -
Standard Practice for Collection of Settled Dust Samples Using Wipe Sampling Methods for Subsequent Determination of Metals
Abstract: 5.1 This practice is intended for the collection of settled dust samples for the subsequent measurement of target metals. The practice is meant for use in the collection of settled dust samples that are of interest in ... -
Standard Test Method for Determining the Hardness of Organic Coatings with a Sward-Type Hardness Rocker
Abstract: 3.1 Sward-type hardness rocker instruments have been used by the coatings industry for more than a half a century as a nondestructive test instrument to measure cure and ultimate surface hardness of organic coatings (see ... -
Standard Test Method for Indirect Tensile (IDT) Strength of Asphalt Mixtures
Abstract: 4.1 The values of IDT strength may be used to evaluate the relative quality of asphalt mixtures in conjunction with laboratory mix design testing or other mechanical testing. The results can also be used to determine the ... -
Standard Practice for Operation of a Roller Chair Tester for Pile Yarn Floor Coverings
Abstract: 5.1 This practice is applicable for use in testing the durability of pile yarn floor covering of all types. 5.2 This practice is designed to simulate the stress on a pile yarn floor covering from the action of weighted ... -
Standard Practice for Collection of Calcined Petroleum Coke Samples for Analysis
Abstract: 4.1 Data obtained from calcined petroleum coke samples are used in commercial transactions, controlling plant operations, and allocating production costs. Use of standard sampling procedures facilitates the task of obtaining ... -
Standard Test Method for Vapor Pressure of Liquefied Petroleum Gases (LPG) (Expansion Method)
Abstract: 5.1 Information on the vapor pressures of liquefied petroleum gas is pertinent to selection of properly designed storage vessels, shipping containers, and customer utilization equipment to ensure safe handling of these ... -
Standard Test Methods for Determining the Biobased Content of Solid, Liquid, and Gaseous Samples Using Radiocarbon Analysis
Abstract: 4.1 This testing method provides accurate biobased/biogenic carbon content results to materials whose carbon source was directly in equilibrium with CO2 in the atmosphere at the time of cessation of respiration or metabolism, ... -
Standard Test Method for Determination of the Weight Percent Individual Volatile Organic Compounds in Air-Dry Low VOC Coatings by Gas Chromatography
Abstract: 5.1 In using Practice D3960 to measure the volatile organic compound content of waterborne coatings, precision can be poor for low volatile organic compound content air-dry coatings if the volatile organic weight percent ... -
