Standard Test Method for Determination of Lead by Graphite Furnace Atomic Absorption Spectrometry (GFAAS) Techniques
Abstract: 5.1 Environmental (including workplace) samples obtained during the assessment or mitigation of lead hazards from buildings and related structures are analyzed to determine lead content in media of concern. This test method ... -
Standard Test Method for Analysis of Engine Coolant for Organic Additives by High Performance Liquid Chromatograph
Abstract: 4.1 This test method provides for the qualitative and quantitative determination of common organic additives in engine coolant in milligrams per liter and only requires a few milliliters of sample per test, with results ... -
Standard Specification for Copper Trolley Wire
Abstract: This specification covers round and grooved hard-drawn copper- and silver-bearing copper trolley wires. Copper materials shall be of such quality and purity that the finished product shall have the properties and characteristics ... -
Standard Test Method for Determination of Phenolic Antioxidants and Fuel System Icing Inhibitors in Aviation Turbine Fuels
Abstract: 5.1 Antioxidants are added to the aviation turbine fuels as protection against oxidation and formation of gums. Fuel system icing inhibitors are used to avoid ice formation in jet fuel under cold environment. The concentration ... -
Standard Guide for Determination of Airborne PFAS in the Indoor Air Environment
Abstract: 5.1 Some PFAS have been implicated in adverse human health impacts (4, 5, 6). Therefore, quantifying PFAS concentrations in indoor air is important for accurate and meaningful exposure analysis and risk assessments. ... -
Standard Guide for Measurement of Gas Permeability and Gas Diffusivity of Carbon and Graphite
Abstract: 6.1 Gas permeability and gas diffusivity are important properties required for correctly modeling and understanding interactions between gases and porous media, for example thermal and radiolytic oxidation, or the escape ... -
Standard Test Method for Determination of Cooling Characteristics of Aqueous Polymer Quenchants for Steel Alloys Using a Silver Probe
Abstract: 5.1 This test method provides a cooling time versus temperature pathway. The results obtained by this test method may be used as a guide in quenchant selection or comparison of quench severities of different quenchants, ... -
Standard Test Method for Gel Time of Solventless Varnishes by Plunger Method
Abstract: 5.1 Gel time is important in determining batch uniformity and some processing characteristics. It is indicative of pot life and shelf life. -
Standard Test Method for Rubber Property—Resilience by Vertical Rebound
Abstract: 4.1 Resilience is a function of both dynamic modulus and internal friction of a rubber. It is very sensitive to temperature changes and to depth of penetration of the plunger. Consequently, resilience values from one type ... -
Standard Practice for Conducting a Coating/Lining Detachment Acoustical Sounding (Tapping) Inspection
Abstract: 5.1 Coating condition assessments are based, in large part, on visual observation of defects in or damage to the coating/ lining system. The visual observation process also identifies precursors of defects (discoloration, ... -
Standard Practice for Requirements of a Quality Management System for Cannabis and Hemp Operations
Abstract: 4.1 Having a concise set of QMS requirements allows users of this practice to understand "what" needs to be established, consistently practiced, monitored, maintained, and improved. 4.2 Guidance on "how" and "why" to ... -
Standard Guide for Good Manufacturing Practices (GMPs) for Cannabis/Hemp-Containing Edibles, Dietary Supplements, Topicals, and Inhaled Products
Abstract: 5.1 This guide provides guidance for the development and implementation of Good Manufacturing Practices (GMPs) for the manufacture of cannabis/hemp-containing edibles, dietary supplements, topicals, and inhaled products ... -
Standard Test Method for Determination of the Degree of Unsaturation of Butyl Rubber by FTIR and Multivariate Analysis
Abstract: 5.1 This infrared absorbance method quantifies the total unsaturation structures in butyl rubber using the characteristic infrared absorbance regions and multivariate analysis. This method accounts for superimposing ... -
Standard Practices for Permanent Monitoring Systems for Electrical Leak Detection and Location
Abstract: 4.1 Geomembranes are used as impermeable barriers to prevent liquids leaking out of landfills, ponds, and other containment facilities. In addition, geomembranes are also used to prevent external liquids leaking into to ... -
Standard Test Method for Determination of Pesticides and Polychlorinated Biphenyls (PCBs) in Aqueous Solution by a Tandem Gas Chromatography/Mass Spectrometry/Mass Spectrometry (GC/MS/MS)
Abstract: 5.1 Pesticides and PCBs are Environmental Protection Agency (EPA)-regulated contaminants in treated drinking water, wastewater, and ground water. Liquid-liquid and solid-phase extraction (SPE) are generally applicable ... -
Standard Test Method for Determination of Relative Rotation to Evaluate the Workability of Asphalt Mixture Using Wireless Particle-Size Sensors
Abstract: 5.1 Workability is one of the main factors that influence the compaction quality and ultimately the performance of asphalt pavement. This method uses the relative rotation measured by the wireless particle-size sensor to ... -
