1.1 This guide covers criteria for determining when probability sampling methods should be used to select locations for placement of environmental monitoring equipment in a building or to select a sample of building occupants for questionnaire administration for a study of indoor air quality. Some...
This specification covers low energy air guns (LEAG), commonly referred to as airsoft guns, air soft guns, or soft air guns, or any combination thereof, which propel a low energy air gun projectile. Non-powder guns, paintball markers, toy products, non-recreational guns such as those used by law...
5.1 Most thermal analysis experiments are carried out under increasing temperature conditions where temperature is the independent parameter. Some experiments, however, are carried out under isothermal temperature conditions where the elapsed time to an event is measured as the independent...
Power tools are essential in most modern industries. However, poorly selected and managed tools can contribute to safety risks, including physical injuries, noise-associated hearing loss, and repetitive motion injuries. Outdated or poorly maintained tools also cost far more to operate than better...
1.1 This guide is intended to determine the relative environmental influence of new substances, consistent with the research and development (R&D) level of effort and is intended to be applied in a logical, tiered manner that parallels both the available funding and the stage of research,...
5.1 New and used petroleum products can contain basic constituents that are present as additives or as degradation products formed during service. The amount of these additives in an oil can be determined by titrating against an acid. The base number is a measure of the amount of basic substance in...
4.1 Intended Users: 4.1.1 This guide may be used by various parties involved in sediment corrective action programs, including regulatory agencies, project sponsors, environmental consultants, toxicologists, risk assessors, site remediation professionals, environmental contractors, and other...
This specification covers the performance requirements and test methods for paintball markers that propel paintballs using energy released from compressed air, compressed gas, or a combination of compressed air and gas. This does not cover non-recreational paintball markers such as those used in...
1.1 This terminology standard is a compilation of terms and corresponding definitions that are used in fire debris analysis. Some legal or scientific terms that are generally understood or defined adequately in other readily available sources are included. 1.2 The values stated in SI units...
1.1 This practice presents a procedure for calculating the unit weights and water contents of soils containing oversize particles when the data are known for the soil fraction with the oversize particles removed. 1.2 This practice also can be used to calculate the unit weights and water contents of...
5.1 The process of model evaluation is critical to establishing both the acceptable uses and limitations of fire models. It is not possible to evaluate a model in total; instead, this guide is intended to provide a methodology for evaluating the predictive capabilities for a specific use....
5.1 Testing is conducted to make technical decisions on materials, processes, and products. With the continued growth in the available test methods for evaluating scientific and technical properties, a quantitative approach is needed to select test methods that have high (or highest) quality...
1.1 This test method measures the change in mass of a rolled erosion control product when specimens are submerged in water for a prescribed period of time. The change in mass is reported as a percentage of the original dry mass of the specimen. 1.2 Units-The values stated in either SI units or...
4.1 This guide is intended for use by those undertaking the development of fire hazard assessments for rail transportation vehicles and products contained within rail transportation vehicles. 4.2 This guide provides information on an approach to develop a fire hazard assessment, but fixed...
4.1 Purpose-This guide provides a process for characterization of existing CCPs placed in active and inactive storage area(s) to assist in potential harvesting strategies. In this guide, information on the following activities required for the safe and effective characterization of CCPs from...
4.1 Intended Use: 4.1.1 This guide may be used by various parties involved in sediment corrective action programs, including regulatory agencies, project sponsors, environmental consultants, toxicologists, risk assessors, site remediation professionals, environmental contractors, and other...
1.1 This specification establishes requirements and characteristics of airsoft gun projectiles which help define whether an airsoft gun is suitable for use in the sport commonly called airsoft, air soft, or soft air. Furthermore, the specification establishes minimum warning and package labeling to...
5.1 The volume fraction of physical components of coal is used as an aid in coal seam correlation and in the characterization of coals for their use in carbonization, gasification, liquefaction, and combustion processes. 5.2 This test method is for use in scientific and industrial research,...
5.1 The parameters KEAC or KIEAC determined by this test method characterize the resistance to crack growth of a material with a sharp crack in specific environments under loading conditions in which the crack-tip plastic region is small compared with the crack depth and the uncracked ligament. The...
