![]() ![]() Softening Point Resins (Mettler Cup and Ball Method) Testing the compatability of lithographic ink resins in high boiling ink solvents by precipitation temperature, manual and automatic mode. Standard Test Method for Determining the Compatability of Resin/Solvent Mixtures by Precipitation Temperature This test method covers the determination of the cloud point of petroleum products and biodiesel fuels that are transparent in layers 40 mm in thickness by an automatic instrument using a constant cooling rate. Standard Test Method for Cloud Point of Petroleum Products (Constant Cooling Rate Method) This test method covers the description of the determination of the cloud point of petroleum products and biodiesel fuels that are transparent in layers 40 mm in thickness by an automatic instrument using a linear cooling rate. Standard Test Method for Cloud Point of Petroleum Products (Linear Cooling Rate Method) This test method covers the description of the determination of the cloud point of petroleum products and biodiesel fuels that are transparent in layers 40 mm in thickness, by an automatic instrument using an optical device. Standard Test Method for Cloud Point of Petroleum Products (Optical Detection Stepped Cooling Method) Standard Classification and Specification for Automotive Service Greases Start temperature 20 to 25☌ below the expected dropping point, heating rate 2 K/min. Heating rate 2 K/min.ĭropping point of waxes (The method duplicates D 566) Place lead ball of 3.2 ☐.1 g on the sample. Pre-melt sample, pour it into the sample cup. Softening point of asphalt and pitch (Mettler cup and ball method) Softening point of pitches (Mettler softening point method) ![]() Note: discontinued without replacement.Ĭhange of birefringence in polarized lightĭropping point of lubricating grease over wide temperature range Melting point of semi-crystalline polymers by the hot stage microscopy method. Melting range of commercial rubber processing chemicals either by use of capillary melting point tubes or by differential scanning calorimetry (DSC) Standard test method for Rubber chemicals-Melting Range The freezing point of an engine coolant may be used to determine the approximate glycol content, provided the glycol type is known. Standard test method for Freezing point of Aqueous Engine Coolant. Pre-melt sample, pour it into the sample cup, heating rate 2 K/min.Īutomatic alternative: ASTM D3954 with DP Standard test method for pour point of petroleum products.įlow ability of the oil is tested when cooled down and crystallization starts, no stirring instrument as used in ASTM D2500.ĭropping point of petroleum waxes including petrolatum Melting point of petroleum waxes (cooling curve)Ī plateau occurs with specimens containing appreciable amounts of hydrocarbons that crystallize at the same temperature, giving up heat of fusion, thus temporarily retarding the cooling rate. The softening point of bitumen in the range from 30 to 157☌ (86 to 315☏) using the ring-and-ball apparatusĪlternative for pure bitumen: ASTM 3461 with DP ![]() ![]() The dropping point of a fat or oil is the temperature at which the test sample will become fluid to flow under the conditions of the test. The cloud point is that temperature at which, under the conditions of this test, a cloud is induced in the test sample caused by the first stage of crystallization. The melting point then must be defined by the specific conditions of the method by which it is determined and, in this case, it is the temperature at which the test sample becomes completely clear and liquid. The temperature at which fat softens and becomes sufficiently fluid to slip in an open capillary tube.įats pass through a stage of gradual softening before they become totally liquid. Slip melting point, AOCS Standard open tube melting point The temperature at which a column of fat in an open capillary tube begins to rise under the conditions specified. Slip melting point ISO Standard (see ISO 6321)
