ASTM D4764 – Standard Test Method for Determination by X-ray Fluorescence Spectroscopy of Titanium Dioxide Content in Paint Description: Significance and Use 4.1 Titanium dioxide pigments are components with high refractive index that significantly influence the opacity, color, durability, and other properties of coatings. This test method for determining titanium dioxide content is quicker and easier …
ASTM D4762 – Standard Guide for Testing Polymer Matrix Composite Materials Description: Significance and Use 4.1 This guide is intended to aid in the selection of standards for polymer matrix composite materials. It specifically summarizes the application of standards from ASTM Committee D30 on Composite Materials that apply to continuous-fiber reinforced polymer matrix composite materials. For …
ASTM D4761 – Standard Test Methods for Mechanical Properties of Lumber and Wood-Based Structural Materials Description: Significance and Use 4.1 These test methods provide procedures that are applicable under true field conditions, such as in a plant with specimens not at moisture equilibrium. 4.2 The data established by these test methods can be used as follows: 4.2.1 Develop …
ASTM D476 – Standard Classification for Dry Pigmentary Titanium Dioxide Products Description: Significance and Use 3.1 This classification is given as an aid in determining the fitness for use of a titanium dioxide pigment for a coating application. It is limited to dry, hiding pigments. It excludes pigment dispersions, and non-hiding specialty titanium dioxide products. Scope …
ASTM D4752 – Standard Practice for Measuring MEK Resistance of Ethyl Silicate (Inorganic) Zinc-Rich Primers by Solvent Rub Description: Significance and Use 4.1 Ethyl silicate zinc-rich primers cure by the reaction of the vehicle with moisture, thereby providing a binder for the zinc. As relative humidity and temperature vary, so does the rate of cure. A …
ASTM D4749 – Standard Test Method for Performing the Sieve Analysis of Coal and Designating Coal Size Description: Significance and Use 4.1 This test method concerns the sieving of coal into designated size fractions for the purpose of characterizing the material as to its particle size distribution for further processing or for commercial purposes. This is …
ASTM D4742 – Standard Test Method for Oxidation Stability of Gasoline Automotive Engine Oils by Thin-Film Oxygen Uptake (TFOUT) Description: Significance and Use 5.1 This test method is used to evaluate oxidation stability of lubricating base oils with additives in the presence of chemistries similar to those found in gasoline engine service. Test results on some …
ASTM D4740 – Standard Test Method for Cleanliness and Compatibility of Residual Fuels by Spot Test Description: Significance and Use 5.1 The four procedures in this test method are used alone or in combination to identify fuels or blends that could result in excessive centrifuge loading, strainer plugging, tank sludge formation, or similar operating problems. 5.2 A …
ASTM D4739 – Standard Test Method for Base Number Determination by Potentiometric Hydrochloric Acid Titration Description: Significance and Use 5.1 New and used petroleum products can contain basic constituents that are present as additives. The relative amount of these materials can be determined by titration with acids. The base number is a measure of the amount …
ASTM D4737 – Standard Test Method for Calculated Cetane Index by Four Variable Equation Description: Significance and Use 5.1 The Calculated Cetane Index by Four Variable Equation is useful for estimating ASTM cetane number when a test engine is not available for determining this property directly and when cetane improver is not used. It may be …
