ASTM D1533 – Standard Test Method for Water in Insulating Liquids by Coulometric Karl Fischer Titration Description: Significance and Use 4.1 Electrical characteristics of an insulating liquid may be affected deleteriously by excessive water content. A high water content may make a dielectric liquid unsuitable for some electrical applications due to deterioration of properties such as …
ASTM D1531 – Standard Test Methods for Relative Permittivity (Dielectric Constant) and Dissipation Factor by Fluid Displacement Procedures (Withdrawn 2012) Description: Significance and Use Permittivity: 5.1.1 Polyethylene and Materials of Permittivity Within 0.1 of That of Polyethylene—Since the permittivity of benzene or 1-cSt silicone fluid is very close to that of polyethylene, these fluids are recommended …
ASTM D153 – Standard Test Methods for Specific Gravity of Pigments Description: Abstract These test methods cover three procedures for determining the specific gravity of pigments, as follows: Test Method A which is for routine testing of several samples simultaneously, Test Method B which is for tests requiring greater accuracy than Test Method A, and …
ASTM D1525- Standard Test Method for Vicat Softening Temperature of Plastics Description: Significance and Use 5.1 Data obtained by this test method is used to compare the heat-softening qualities of thermoplastic materials. 5.2 This test method is useful in the areas of quality control, development, and characterization of plastic materials. Scope 1.1 This test method covers determination of …
ASTM D1524 – Standard Test Method for Visual Examination of Used Electrical Insulating Liquids in the Field Description: Significance and Use 4.1 By use of this test method and Test Methods D1500 or D2129 the color and condition of a test specimen of electrical insulating liquid may be estimated during a field inspection, thus assisting in the decision as to …
ASTM D1518 – Standard Test Method for Thermal Resistance of Batting Systems Using a Hot Plate (Withdrawn 2023) Description: Significance and Use 4.1 The thermal resistance of a batting or batting/fabric system is of considerable importance in determining its suitability for use in fabricating cold weather protective clothing, sleeping bags, and bedding systems. The thermal interchange …
ASTM D1514 – Standard Test Method for Carbon Black—Sieve Residue Description: Significance and Use 4.1 The quantity of sieve residue of carbon black is important in some molded or extruded products as it may relate to the surface appearance of those products. The maximum residue in each application is normally determined and agreed to between the …
ASTM D1513 – Standard Test Method for Carbon Black, Pelleted—Pour Density Description: Significance and Use 4.1 Pour density is a function of the degree of compaction during pelletization. It is strongly influenced by and inversely proportional to structure (OAN). Pour density of carbon black is useful for estimating the weight-to-volume relationship for certain applications, such as …
ASTM D1512 – Standard Test Methods for Carbon Black—pH Value Description: Significance and Use 3.1 The pH level of a carbon black is known to affect the vulcanization of some rubber compounds. Scope 1.1 These test methods, Test Method A—Boiling Slurry and Test Method B—Sonic Slurry, are used to indicate the pH of the carbon black surface …
ASTM D1511 – Standard Test Method for Carbon Black—Pellet Size Distribution Description: Significance and Use 4.1 The variation in the size of the pellets may relate to the level of dispersion and to the ease of handling. Due to the many other variables that influence dispersion and handling, the significance of pellet size must be determined …
