ASTM D4212 – Standard Test Method for Viscosity by Dip-Type Viscosity Cups Description: Significance and Use 5.1 Viscosity is a measure of the fluidity of a material. Viscosity data are useful in the determination of the ease of stirring, pumping, dip coating, or other flow-related properties of paints and related fluids. 5.2 This type of cup is …
ASTM D421 – Standard Practice for Dry Preparation of Soil Samples for Particle-Size Analysis and Determination of Soil Constants (Withdrawn 2016) Description: Significance and Use This practice can be used to prepare samples for particle-size and plasticity tests where it is desired to determine test values on air-dried samples, or where it is known that …
ASTM D4208 – Standard Test Method for Total Chlorine in Coal by the Oxygen Vessel Combustion/Ion Selective Electrode Method Description: Significance and Use 5.1 The purpose of this test method is to measure the total chlorine content of coal. The chlorine content of coals may be useful in the evaluation of slagging problems, corrosion in engineering …
ASTM D4206 – Standard Test Method for Sustained Burning of Liquid Mixtures Using the Small Scale Open-Cup Apparatus Description: Significance and Use 4.1 Mixtures of flammable liquids and nonflammable liquids, such as an alcohol and water mixture, are classified by the U. S. Government by the definition of flammable liquid based on a closed-cup flash point …
ASTM D4200 – Standard Test Method for Evaluating Inhibitory Effects of Ink Grids on Membrane Filters Description: Significance and Use 5.1 This test method may be applied to determine the suitability of grid-marked membrane filters for use in bacteriological culture techniques for the detection and enumeration of bacterial organisms. 5.2 A particularly sensitive organism and growth conditions …
ASTM D4193 – Standard Test Method for Thiocyanate in Water Description: Significance and Use 5.1 This test method is useful for analysis of many natural waters that contain thiocyanate from organic decomposition products and waste water discharges. Some industrial wastes, such as those from the metallurgical processing of gold ores, steel industry, petroleum refining, and coal …
ASTM D4189 – Standard Test Method for Silt Density Index (SDI) of Water Description: Significance and Use 5.1 The SDI can serve as a useful indication of the quantity of particulate matter in water. 5.2 The SDI can be used to determine effectiveness of various processes such as filtration or clarification used to remove particulate matter. 5.3 The …
ASTM D4176 – Standard Test Method for Free Water and Particulate Contamination in Distillate Fuels (Visual Inspection Procedures) Description: Significance and Use 5.1 It has long been the practice to include in fuel specifications a requirement that the fuel be clear and bright and free of visible particulate matter (see Note 1). However, there has been no standard method …
ASTM D4172 – Standard Test Method for Wear Preventive Characteristics of Lubricating Fluid (Four-Ball Method) Description: Significance and Use 5.1 This test method can be used to determine the relative wear preventive properties of lubricating fluids in sliding contact under the prescribed test conditions. No attempt has been made to correlate this test with balls in …
ASTM D4171 – Standard Specification for Fuel System Icing Inhibitors Description: Abstract This specification covers additives for aviation fuels used to inhibit ice formation in aircraft fuel systems. Three types of fuel system icing inhibitors are provided as follows: type I – ethylene glycol monomethyl ether, type II – anhydrous isopropanol, and type III – …
