1.1 This test method covers the determination of total uranium, by mass concentration, in water within the calibrated range of the instrument, 0.1?μg/L or greater. Samples with uranium mass concentrations above the laser phosphorimeter dynamic range are diluted to bring the concentration to...
1.1 Compositing and subsampling are key links in the chain of sampling and analytical events that must be performed in compliance with project objectives and instructions to ensure that the resulting data are representative. This guide discusses the advantages and appropriate use of composite...
1.1 This test method covers the determination of the relative efficacy of dynamic solvent systems for dissolving water-formed deposits that have been removed from the underlying material or deposits attached to the underlying material. 1.2 The nature of this test method is such that...
5.1 Many microplastic particles enter the environment, including ambient waters and drinking water supplies, via wastewater sources resulting from both industrial processes and consumer products. The presence of high percentages of organic particles, including cellulose material originating from...

This specification provides a description of a test method for protective headgear used in horse sports and horseback riding that will measure the ability of the headgear to reduce head acceleration when impacting objects of various shapes. Materials covered by this specification include the pair...
1.1 This test method covers the determination of the specific gravity of soil solids by means of a gas pycnometer. Particle size is limited by the dimensions of the test specimen container of the particular pycnometer being used. 1.2 Test Method D854 may be used instead of or in conjunction with...
1.1 This practice is intended to assist in the selection of sorbents and procedures for the sampling and analysis of ambient (1),2 indoor (2), and workplace (3, 4) atmospheres for a variety of common volatile organic compounds (VOCs). It may also be used for measuring emissions from materials in...
1.1 This guide is intended to serve as a foundation for understanding when to use emission testing methods designed for volatile organic compounds (VOCs) to determine area-specific emission rates that are typically used in modeling indoor air VOC concentrations and when to use emission testing...
1.1 This practice covers a means for calibrating ambient, workplace, or indoor ozone monitors, and for certifying transfer standards to be used for that purpose. 1.2 This practice describes means by which dynamic streams of ozone in air can be designated as primary ozone standards. 1.3 The...
These specifications cover the design and performance requirements, and associated test procedures for helmets used in the activities of skateboarding and trick roller skating. When tested, the helmets shall meet specified requirements for the peak acceleration and time duration, headforms and...
1.1 This practice covers a means for calibrating ambient, workplace, or indoor ozone monitors, and for certifying transfer standards to be used for that purpose. 1.2 This practice describes means by which dynamic streams of ozone in air can be designated as primary ozone standards. 1.3 The...
1.1 This test method is used to evaluate the ability of erosion control products (ECP) to protect slopes from rainfall-induced erosion using an adjustable tilting bed slope. The standard slopes range from 2:1 to 4:1 (H:V) having a target rainfall intensity of 3.5 in./h [90 mm/h]. 1.2 There are...
1.1 This practice specifies the test equipment and procedures for determining the physiological responses of subjects wearing a protective clothing ensemble. 1.2 This practice covers the physiological measurement of internal body core temperature, skin temperature, exposure time, heart rate...
1.1 This test method covers the physiological measurement of internal body core temperature, skin temperature, thermal exposure time, heart rate response, oxygen consumption, and whole body sweat rate, to assess the effectiveness of personal cooling systems (PCS) in reducing the effects of thermal...
1.1 This test method covers the procedure for the determination of the number of drops required for a dynamic cone penetrometer with a 2.3-kg [5-lbm] drop hammer falling 508 mm [20 in.] to penetrate a certain depth in compacted backfill. 1.2 The device is used in the compaction verification...
4.1 This test standard describes how to evaluate the relative sensitivity of materials and components to dynamic pressure impacts by various gaseous fluid media (can include gas mixtures). 4.2 Changes or variations in test specimen configurations, thickness, preparation, and cleanliness can...
5.1 This guide provides information on testing systems and their components used for measuring responses of CO alarms or detectors subjected to gases, vapors, and their mixtures. Components of a testing system include a chamber, clean air supply module, humidification module, gas and vapor delivery...
1.1 This test method covers the procedures for determining in-place properties of non-frozen, unbound soil and soil aggregate mixtures such as total density, gravimetric water content and relative compaction by measuring the intrinsic impedance of the compacted soil. 1.1.1 The method and device...
5.1 This test method provides a means for determining the specific optical density of the smoke generated by specimens of materials, products, or assemblies under the specified exposure conditions. Values determined by this test are specific to the specimen in the form and thickness tested and are...
