ASTM D1577 – Standard Test Methods for Linear Density of Textile Fibers Description: Significance and Use 4.1 Option A for bundle weighing of Test Method D1577 is used in the trade for acceptance testing of commercial shipments. Option B for single-fiber weighing and Option C for the vibroscope may be used for acceptance testing (see Section 37); however, caution …
ASTM D156 – Standard Test Method for Saybolt Color of Petroleum Products (Saybolt Chromometer Method) Description: Significance and Use 5.1 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 D1557 – Standard Test Methods for Laboratory Compaction Characteristics of Soil Using Modified Effort (56,000 ft-lbf/ft3 (2,700 kN-m/m3)) Description: Significance and Use 5.1 Soil placed as engineering fill (embankments, foundation pads, road bases) is compacted to a dense state to obtain satisfactory engineering properties such as shear strength, compressibility, or permeability. In addition, foundation soils are …
ASTM D1552 – Standard Test Method for Sulfur in Petroleum Products by High Temperature Combustion and Infrared (IR) Detection or Thermal Conductivity Detection (TCD) Description: Significance and Use 4.1 This test method provides a means of monitoring the sulfur level of various petroleum products and additives. This knowledge can be used to predict performance, handling, or …
ASTM D1545 – Standard Test Method for Viscosity of Transparent Liquids by Bubble Time Method Description: Abstract This test method covers the procedures for determining the viscosity of transparent liquids by bubble time method. The transparent liquids should be free from crystalline or gel particles. Test apparatus include a constant-temperature bath, standard viscosity tubes, a …
ASTM D1544 – Standard Test Method for Color of Transparent Liquids (Gardner Color Scale) Description: Significance and Use 3.1 This test method applies to drying oils, varnishes, fatty acids, polymerized fatty acids, and resin solutions. Its application to other materials has not been tested. Scope 1.1 This test method covers the measurement of the color of transparent …
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 …
