ASTM D287 – Standard Test Method for API Gravity of Crude Petroleum and Petroleum Products (Hydrometer/Method) Description: Significance and Use 5.1 Accurate determination of the gravity of petroleum and its products is necessary for the conversion of measured volumes to volumes at the standard temperature of 60 °F (15.56 °C). 5.2 This procedure is most suitable for determining the …
ASTM D2868 – Standard Test Method for Nitrogen Content (Kjeldahl) and Hide Substance Content of Leather, Wet Blue and Wet White Description: Significance and Use 4.1 The nitrogen content as determined by this test method is normally considered to be related to the amount of hide substance (protein fiber) present in the leather sample. A factor …
ASTM D2867 – Standard Test Methods for Moisture in Activated Carbon Description: Significance and Use 4.1 The moisture content of activated carbon is often required to define and express its properties in relation to the net weight of the carbon. 4.2 The moisture content of activated carbon packed in typical shipping containers will usually increase during transportation …
ASTM D2866 – Standard Test Method for Total Ash Content of Activated Carbon Description: Significance and Use 4.1 In specific end uses, the amount and composition of the ash may influence the capabilities and certain desired properties of activated carbon. 4.2 Other automated methods for determination of ash content, such as combusting the carbon in a thermogravimetric …
ASTM D2863 – Standard Test Method for Measuring the Minimum Oxygen Concentration to Support Candle-Like Combustion of Plastics (Oxygen Index) Description: Significance and Use 5.1 This test method provides for the measuring of the minimum concentration of oxygen in a flowing mixture of oxygen and nitrogen that will just support flaming combustion of plastics. Correlation with …
ASTM D2862 – Standard Test Method for Particle Size Distribution of Granular Activated Carbon Description: Significance and Use 4.1 It is necessary to know the distribution of particle sizes of granular activated carbon in order to provide proper contact of gases or liquid in a packed bed of the material. Changes in particle size distribution can …
ASTM D2859 – Standard Test Method for Ignition Characteristics of Finished Textile Floor Covering Materials Description: Significance and Use 5.1 This test method provides a procedure for identification of those finished textile floor covering materials that can be rated as flame-resistant under specific controlled laboratory conditions. 5.2 This test method does not specify the use of an …
ASTM D2857 – Standard Practice for Dilute Solution Viscosity of Polymers Description: Significance and Use 5.1 The determination of dilute solution viscosity provides one item of information towards the molecular characterization of polymers. When viscosity data are used in conjunction with other molecular parameters, the properties of polymers depending on their molecular structure may be predicted. …
ASTM D2856 – Standard Test Method for Open-Cell Content of Rigid Cellular Plastics by the Air Pycnometer (withdrawn 2006) Description: Scope 1.1 Cellular plastics are composed of the membranes or walls of polymer separating small cavities or cells. These cells may be interconnecting (open cell), non-connecting (closed cell), or any combination of these types. This …
ASTM D2854 – Standard Test Method for Apparent Density of Activated Carbon Description: Significance and Use 4.1 This test method provides a method for determining the packed density of a bed of granular activated carbon. Determination of the packed density is essential when designing vessels to hold the material and for ordering purposes when procuring materials …
