ASTM D5761-23(Practice)
Standard Practice for Emulsification/Suspension of Multiphase Fluid Waste Materials

SIGNIFICANCE AND USE
5.1 This practice is intended as a solution to the difficulty of obtaining reproducible test results from heterogeneous samples.  
5.2 This practice works best with multilayered liquids, but can also be applied to samples with solid particles that are sufficiently small in size to be suspended in an emulsion.  
5.3 The emulsified/suspended sample can be used for all bulk property testing such as microwave digestion/inductively coupled argon plasma (ICAP), ion chromatography, heat of combustion, ash content, water, nonvolatile residue, and pH. It may be prudent to retain a portion of the sample in its original, multiphase form for some types of analyses.
SCOPE
1.1 This practice covers the generation of a uniform mixture or emulsion from multiphase samples which are primarily liquid in order to facilitate sample preparation, transfer, and analysis.  
1.2 This practice is designed to keep a multiphase fluid sample in an emulsified/suspended state long enough to take a single, composite sample that is representative of the sample as a whole. The sample may reform multiple layers after standing.  
1.3 The emulsion/suspension generated by following this practice can be used only for analytical procedures designed for the total sample and procedures not significantly affected by the emulsifier or the presence of an emulsion/suspension.  
1.4 This practice assumes that a representative sample of not more than 1 L has been obtained.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practice for Standardized Aquatic Microcosms: Fresh Water

SIGNIFICANCE AND USE
5.1 A microcosm test is conducted to obtain information concerning toxicity or other effects of a test material on the interactions among three trophic levels (primary, secondary, and detrital) and the competitive interactions within each trophic level. As with most natural aquatic ecosystems, the microcosms depend upon algal production (primary production) to support the grazer trophic level (secondary production), which along with the microbial community are primarily responsible for the nutrient recycling necessary to sustain primary production. Microcosm initial condition includes some detritus (chitin and cellulose) and additional detritus is produced by the system. The microcosms include ecologically important processes and organisms representative of ponds and lakes, but are non-site specific. To the extent possible, all solutions are mixtures of distilled water and reagent grade chemicals (see Section 8) and all organisms are available in commercial culture collections.  
5.2 The species used are easy to culture in the laboratory and some are routinely used for single species toxicity tests (Guide E729; Practice D3978, Guides E1192 and E1193). Presumably acute toxicity test results with some of these species would be available prior to the decision to undertake the microcosm test. If available, single species toxicity results would aid in distinguishing between indirect and direct effects.  
5.3 These procedures are based mostly on published methods (4-6), interlaboratory testing (7-10, 11), intermediate studies (12-23, 24), statistical studies  (25-27) and mathematical simulation results  (28). Newer studies on jet fuels have been reported (29)(See 15.1 for multivariate statistical analyses) and on the implications of multispecies testing for pesticide registration (30). Environmental Protection Agency, (EPA) and Food and Drug Administration, (FDA) published similar microcosm tests (31). The methods described here were used to determine the criteria for A...
SCOPE
1.1 This practice covers procedures for obtaining data concerning toxicity and other effects of a test material to a multi-trophic level freshwater community, independent of the location of the test.  
1.2 These procedures also might be useful for studying the fate of test materials and transformation products, although modifications and additional analytical procedures might be necessary.  
1.3 Modification of these procedures might be justified by special needs or circumstances. Although using appropriate procedures is more important than following prescribed procedures, results of tests conducted using unusual procedures are not likely to be comparable to results of many other tests. Comparison of results obtained using modified and unmodified versions of these procedures might provide useful information concerning new concepts and procedures for conducting multi-trophic level tests.  
1.4 This practice is arranged as follows:

Standard Practice for Operating the Severe Wastewater Analysis Testing Apparatus

SIGNIFICANCE AND USE
5.1 Domestic wastewater headspace environments are corrosive due to the presence of sewer gases and sulfuric acid generated during the biogenic sulfide corrosion process.5 This operating procedure provides an accelerated exposure to sewer gases and concentration of sulfuric acid commonly produced by bacteria within these sewer environments.6  
5.2 The results obtained by the use of this practice can be a means for estimating the protective barrier qualities of a protective coating or lining for use in severe sewer conditions.  
5.3 Some protective coatings or linings may not withstand the exposure temperature specified in this practice but have demonstrated satisfactory performance in actual sewer exposures, which are at lower temperatures.
SCOPE
1.1 This practice covers the basic apparatus, procedures, and conditions required to create and maintain the severe wastewater analysis testing apparatus used for testing a protective coating or lining.  
1.2 This apparatus may simulate the pertinent attributes of a typical domestic severe wastewater headspace (sewer) environment. The testing chamber comprises two phases: (1) a liquid phase containing a prescribed acid and saline solution, and (2) a vapor phase consisting of air, humidity, and concentrated sewer gas (Note 1). The temperature of the test chamber is elevated to create accelerated conditions and reaction rates.
Note 1: For the purposes of this practice, sewer gas is composed of hydrogen sulfide, carbon dioxide, and methane gas.  
1.3 Caution—This practice can be extremely hazardous. All necessary precautions need to be taken when working with sewer gas, sulfuric acid, and a glass tank. It is highly recommended that a professional testing laboratory experienced in testing with hydrogen sulfide, carbon dioxide, and methane gases perform this practice.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Some specific hazards statements are given in Section 8 on Hazards.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Selection of Test Methods to Determine Rate of Fluid Permeation Through Geomembranes for Specific Applications

SIGNIFICANCE AND USE
5.1 The principal characteristic of geomembranes is their intrinsically low permeability to a broad range of gases, vapors, and liquids, both as single-component fluids and as complex mixtures of many constituents. As low-permeable materials, geomembranes are being used in a wide range of engineering applications in geotechnical, environmental, and transportation areas as barriers to control the migration of mobile fluids and their constituents. The range of potential permeants is broad and the service conditions can differ greatly. This guide shows users test methods available for determining the permeability of geomembranes to various permeants.  
5.2 The transmission of various species through a geomembrane is subject to many factors that must be assessed in order to be able to predict its effectiveness for a specific service. Permeability measurements are affected by test conditions, and measurements made by one method cannot be translated from one application to another. A wide variety of permeability tests have been devised to measure the permeability of polymeric materials; however, only a limited number of these procedures have been applied to geomembranes. Test conditions and procedures should be selected to reflect actual service requirements as closely as possible. It should be noted that field conditions may be difficult to model or maintain in the laboratory. This may impact apparent performance of geomembrane samples.  
5.3 This guide discusses the mechanism of permeation of mobile chemical species through geomembranes and the permeability tests that are relevant to various types of applications and permeating species. Specific tests for the permeability of geomembranes to both single-component fluids and multicomponent fluids that contain a variety of permeants are described and discussed.
SCOPE
1.1 This guide covers selecting one or more appropriate test methods to assess the permeability of all candidate geomembranes for a proposed specific application to various permeants. The widely different uses of geomembranes as barriers to the transport and migration of different gases, vapors, and liquids under different service conditions require determinations of permeability by test methods that relate to and simulate the service. Geomembranes are nonporous, homogeneous materials that are permeable in varying degrees to gases, vapors, and liquids on a molecular scale in a three-step process by: (1) dissolution in or absorption by the geomembrane on the upstream side, (2) diffusion through the geomembrane, and (3) desorption on the downstream side of the barrier.  
1.2 The rate of transmission of a given chemical species, whether as a single permeant or in mixtures, is driven by its chemical potential or in practical terms by its concentration gradient across the geomembrane. Various methods to assess the permeability of geomembranes to single component permeants, such as individual gases, vapors, and liquids are referenced and briefly described.  
1.3 Various test methods for the measurement of permeation and transmission through geomembranes of individual species in complex mixtures such as waste liquids are discussed.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Silica-Based Sediments for the Evaluation of Stormwater Treatment Devices

SCOPE
1.1 This specification covers the minerology, specific gravity, and particle size distributions (PSDs) of silica-based sediments to be used in the laboratory performance testing of stormwater treatment devices as well as criteria defining acceptable error for the target PSDs.  
1.2 Silica-based sediment is used as a surrogate material for performance and scour determinations for some manufactured stormwater treatment devices such as hydrodynamic separators and filters. These data are used to gain regulatory approvals within certain jurisdictions.  
1.3 Acceptance of test results attained according to this specification may be subject to specific requirements set by a Quality Assurance Project Plan, a specific verification protocol, or a policy set by an Authority Having Jurisdiction (AHJ). It is advised to review one or all of the above to ensure compliance.  
1.4 The values stated in inch-pound units are to be regarded as standard, except for methods to establish and report sediment concentration and particle size. It is convention to exclusively describe sediment concentration in mg/L and particle size in mm or μm, both of which are SI units. The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard. Reporting of test results in units other than inch-pound units shall be regarded as conforming with this test method.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Silica-based sediment is considered hazardous under the OSHA Hazard Communications Standard (29 CFR 1910.1200).

Standard Specification for Circular Precast Reinforced Concrete Manhole Sections

ABSTRACT
This specification covers the manufacture and purchase requirements of products used for the assembly and construction of circular vertical precast reinforced concrete manholes and structures used in sewer and water works. Reinforced concrete shall consist of cementitious materials, mineral aggregates, and water, in which steel reinforcement has been embedded in such a manner so that the steel reinforcement and concrete act together. Aggregates shall conform to the specification , except that the requirements for gradation shall not apply. Minimum compressive strength of concrete manhole products covered must meet the requirement. The aggregates shall be sized, graded, proportioned, and mixed with such proportions of cementitious materials and water as will produce as homogeneous concrete mixture of such quality that the products will conform to the test and design requirements. Concrete products shall be subjected to either steam or water curing. Test methods such as compression and absorption testing shall be performed.
SCOPE
1.1 This specification covers the manufacture and purchase requirements of products used for the assembly and construction of circular vertical precast reinforced concrete manholes and structures used in sewer, drainage, and water works.  
1.2 Part I, Sections 1 – 11, of this specification presents general requirements and requirements that are common to each precast concrete product covered by this specification.
