ASTM D396 – Standard Specification for Fuel Oils Description: Abstract This specification covers grades of fuel oil intended for use in various types of fuel-oil-burning equipment under various climatic and operating conditions. These grades include the following: Grades No. 1 S5000, No. 1 S500, No. 2 S5000, and No. 2 S500 for use in domestic …
ASTM D395 – Standard Test Methods for Rubber Property—Compression Set Description: Significance and Use 4.1 Compression set tests are intended to measure the ability of rubber compounds to retain elastic properties after prolonged action of compressive stresses. The actual stressing service may involve the maintenance of a definite deflection, the constant application of a known force, …
ASTM D3948 – Standard Test Method for Determining Water Separation Characteristics of Aviation Turbine Fuels by Portable Separometer Description: Significance and Use 5.1 This test method provides a measure of the presence of surfactants in aviation turbine fuels. Like previous obsolete Test Methods D2550 and D3602, and current Test Methods D7224 and D8073, this test method can detect carryover traces of refinery …
ASTM D3946 – Standard Test Method for Evaluating the Bacteria Resistance of Water-Dilutable Metalworking Fluids (Withdrawn 2004) Description: Scope 1.1 This test method covers evaluating relative bioresistance of aqueous metalworking fluids by challenging them with a biological inoculum prepared from specific deteriorated metalworking fluid from the user’s site. 1.2 This standard does not purport to …
ASTM D3944 – Standard Test Method for Solidification Point of Petroleum Wax Description: Significance and Use 5.1 The related methods of determining the melt point of petroleum wax are relatively time-consuming. This method endeavors to reduce the duration of testing significantly and at the same time maintain a reasonable precision. This method can be useful for …
ASTM D3941 – Standard Test Method for Flash Point by the Equilibrium Method With a Closed-Cup Apparatus Description: Significance and Use 5.1 This test method, using a slow rate of heating, provides a uniform temperature throughout the specimen. The slow rate of heating is necessary because of the low thermal conductivity of some liquids such as …
ASTM D3939 – Standard Test Method for Snagging Resistance of Fabrics (Mace) Description: Significance and Use 5.1 This test method is not considered satisfactory for acceptance testing of commercial shipments of fabrics because the between-laboratory precision of the test method is poor (see 15.1). 5.1.1 If there are differences of practical significance between reported test results for two …
ASTM D3938 – Standard Guide for Determining or Confirming Care Instructions for Apparel and Other Textile Products Description: Significance and Use 4.1 This is a guide to help a manufacturer distributor, or importer establish a reasonable basis for care information. 4.1.1 The manufacturer, distributor, or importer should possess, prior to sale, reliable evidence that the product was …
ASTM D3936 – Standard Test Method for Resistance to Delamination of the Secondary Backing of Pile Yarn Floor Covering Description: Significance and Use 5.1 This test method is used for acceptance testing of commercial shipments. Comparative tests as directed in 5.2 may be advisable. 5.2 In a case of a dispute arising from differences in reported test results when …
ASTM D3934 – Standard Test Method for Flash/No Flash Test—Equilibrium Method by a Closed-Cup Apparatus Description: Significance and Use 5.1 This test method ensures that before the flash test is run the air/vapor space above the specimen has attained a saturation concentration of vapor by using standard closed cups under equilibrium conditions. The saturation concentration of …
