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 – …
ASTM D4170 – Standard Test Method for Fretting Wear Protection by Lubricating Greases Description: Significance and Use 5.1 This test method is used to evaluate the property of lubricating greases to protect oscillating bearings from fretting wear. This method, used for specification purposes, differentiates among greases allowing low, medium, and high amounts of fretting wear under …
ASTM D4169 – Standard Practice for Performance Testing of Shipping Containers and Systems Description: Significance and Use 4.1 This practice provides a guide for the evaluation of shipping units in accordance with a uniform system, using established test methods at levels representative of those occurring in actual distribution. The recommended test levels are based on available …
ASTM D4157 – Standard Test Method for Abrasion Resistance of Textile Fabrics (Oscillatory Cylinder Method) Description: Significance and Use 5.1 The measurement of the resistance to abrasion of textile and other materials is very complex. The resistance to abrasion is affected by many factors, such as the inherent mechanical properties of the fibers; the dimensions of …
ASTM D4145 – Standard Test Method for Coating Flexibility of Prepainted Sheet Description: Significance and Use 4.1 Organic coatings on precoated sheet are subjected to stresses when fabricated into products by roll forming, brake bending, or other deformation processes. These stresses can exceed the flexibility or adhesive strength of the coating, resulting in fracture of the …
