ASTM D1509 – Standard Test Methods for Carbon Black—Heating Loss Description: Significance and Use 4.1 In addition to determining the heating loss (primarily moisture content) of carbon black, these drying conditions are used to prepare samples prior to performing other carbon black tests. 4.2 When larger samples are prepared for other tests, use an open vessel of …
ASTM D1508 – Standard Test Method for Carbon Black, Pelleted Fines and Attrition Description: Significance and Use 4.1 Method A, Fines—The fines content of carbon black is related to the bulk flowability, dustiness, and, in some instances, the level of dispersion. Due to the many other variables that influence dispersion and handling, the significance of fines …
ASTM D1506 – Standard Test Methods for Carbon Black—Ash Content Description: Significance and Use 4.1 The ash content of a carbon black is the amount of non-carbon components present after combustion. Primary contributants to ash are the manufacturing process water and the catalyst in the feedstock. Scope 1.1 These test methods cover the determination of the ash …
ASTM D1505 – Standard Test Method for Density of Plastics by the Density-Gradient Technique Description: Significance and Use 4.1 The density of a solid is a conveniently measurable property which is frequently useful as a means of following physical changes in a sample, as an indication of uniformity among samples, and a means of identification. 4.2 This …
ASTM D1500 – Standard Test Method for ASTM Color of Petroleum Products (ASTM Color Scale) Description: Significance and Use 4.1 Determination of the color of petroleum products is used mainly for manufacturing control purposes and is an important quality characteristic, since color is readily observed by the user of the product. In some cases, the color …
ASTM D150 – Standard Test Methods for AC Loss Characteristics and Permittivity (Dielectric Constant) of Solid Electrical Insulation Description: Significance and Use 5.1 Permittivity—Insulating materials are used in general in two distinct ways, (1) to support and insulate components of an electrical network from each other and from ground, and (2) to function as the dielectric …
ASTM D1499 – Standard Practice for Filtered Open-Flame Carbon-Arc Exposures of Plastics Description: Significance and Use 4.1 The ability of a plastic material to resist deterioration of its electrical, mechanical, and optical properties caused by exposure to light, heat, and water can be very significant for many applications. This practice is intended to induce property changes …
ASTM D1498- Standard Test Method for Oxidation-Reduction Potential of Water Description: Abstract This test method covers the apparatus and procedure for the electrometric measurement of oxidation-reduction potential (ORP) in water. The test method described has been designed for the routine and process measurement of oxidation-reduction potential. ORP is defined as the electromotive force between a …
ASTM D1492 – Standard Test Method for Bromine Index of Aromatic Hydrocarbons by Coulometric Titration Description: Significance and Use 5.1 This test method is useful as an internal quality control tool, and for use in development or research work on industrial aromatic hydrocarbons and related materials. This test method gives a broad indication of olefinic content. …
ASTM D149 – Standard Test Method for Dielectric Breakdown Voltage and Dielectric Strength of Solid Electrical Insulating Materials at Commercial Power Frequencies Description: Significance and Use 5.1 The dielectric strength of an electrical insulating material is a property of interest for any application where an electrical field will be present. In many cases the dielectric strength …
