5.1 Turbidity is monitored to help control processes, monitor the health and biology of aquatic environments and to determine the impact of environmental events such as storms, floods, runoff, etc. Turbidity is undesirable in drinking water, plant-effluent waters, water for food and...
4.1 Water-insoluble materials present in a solvent expected to be completely water miscible may interfere with many uses of the solvent. This test method provides a measure of the miscibility of water-soluble solvents with a polar medium-water. It also provides a qualitative indication of the...
1.1 These test methods cover procedures for the sampling and chemical analysis of inorganic alkaline detergents. 1.2 The procedures appear in the following order: Sections Caustic Soda: ?Sampling 5 ?Total Alkalinity as Sodium Oxide (Na2O) 6 - 8 ?Sodium Hydroxide (NaOH) ?9 - 11 ?Carbonate as Sodium...
5.1 A rapid and routine procedure for determining biomass of the living microorganisms in cultures, waters, wastewaters, and in plankton and periphyton samples taken from surface waters is frequently of vital importance. However, classical techniques such as direct microscope counts,...
5.1 The most direct and accessible methods for obtaining the color coordinates of object colors are by instrumental measurement using spectrophotometers or colorimeters with either hemispherical or bidirectional optical measuring systems. This test method provides procedures for such measurement by...
This test method covers the apparatus and procedure for the electrometric measurement of oxidation-reduction potential (ORP) in water. The test method described has been designed for the routine and process measurement of oxidation-reduction potential. ORP is defined as the electromotive force...
5.1 This test method utilizes large-scale testing equipment and procedures established at a variety of testing laboratories over the last 30 years. 5.2 This method is useful in evaluating ECPs and their installation to reduce soil loss and sediment concentrations when exposed to defined rainfall...
This guide describes methods of testing and specifications for electrical insulating oils of petroleum origin intended for use in electrical cables, transformers, oil circuit breakers, and other electrical apparatus where the oils are used as insulating, or heat transfer media, or both. This guide...
This test method covers the procedures for determining soluble sulfate ions present in water or a filtrate using a photometer to measure the turbidity of precipitated barium sulfate. This test method also details a method for standardizing the photometer to be used. The soluble sulfate ions...
1.1 This specification covers a limit for thermal residual stress in reusable annealed glass laboratory apparatus as determined by prescribed photoelastic measurement procedures. 1.2 In broad classification, the laboratory glassware items covered by this specification, but not limited to, are:...
5.1 Method Considerations-The objective of most groundwater sampling programs is to obtain samples that are similar in composition to that of the formation water near the well screen. The low-flow purging and sampling method uses the stabilization of indicator parameters to determine when the pump...
1.1 This test method describes a simple procedure for the detection of Legionella pneumophila (L. pneumophila) in potable water and non-potable waters (cooling towers, for example). This procedure describes a liquid culture method based on a bacterial enzyme technology. The detection of L....
1.1 This test method covers the determination of silica in water and waste water; however, the analyst should recognize that the precision and accuracy statements for reagent water solutions may not apply to waters of different matrices. 1.2 This test method is a colorimetric method that determines...
This document specifies a method to determine the turbidity point of petroleum products based on distillates from crude oil. This document also specifies how to convert the turbidity point to an aniline point equivalent. This document describes a procedure using automated or automatic...
