ASTM E681 – Standard Test Method for Concentration Limits of Flammability of Chemicals (Vapors and Gases) Description: Significance and Use 5.1 The LFL and UFL of gases and vapors define the range of flammable concentrations in air. 5.2 This method measures the LFL and UFL for upward (and partially outward) flame propagation. The limits for downward flame …
ASTM E647 – Standard Test Method for Measurement of Fatigue Crack Growth Rates Description: Significance and Use 5.1 Fatigue crack growth rate expressed as a function of crack-tip stress-intensity factor range, da/dN versus ΔK, characterizes a material’s resistance to stable crack extension under cyclic loading. Background information on the ration-ale for employing linear elastic fracture mechanics to …
ASTM E595 – Standard Test Method for Total Mass Loss and Collected Volatile Condensable Materials from Outgassing in a Vacuum Environment Description: Significance and Use 5.1 This test method evaluates, under carefully controlled conditions, the changes in the mass of a test specimen on exposure under vacuum to a temperature of 125 °C and the mass of …
ASTM E537 – Standard Test Method for Thermal Stability of Chemicals by Differential Scanning Calorimetry Description: Significance and Use 5.1 This test method is useful in detecting potentially hazardous reactions including those from volatile chemicals and in estimating the temperatures at which these reactions occur and their enthalpies (heats). This test method is recommended as an …
ASTM E415 – Standard Test Method for Analysis of Carbon and Low-Alloy Steel by Spark Atomic Emission Spectrometry Description: Significance and Use 5.1 This test method for the spectrometric analysis of metals and alloys is primarily intended to test such materials for compliance with compositional specifications. It is assumed that all who use this test method …
ASTM E399 – Standard Test Method for Linear-Elastic Plane-Strain Fracture Toughness of Metallic Materials Description: Significance and Use 5.1 The property KIc determined by this test method characterizes the resistance of a material to fracture in a neutral environment in the presence of a sharp crack under essentially linear-elastic stress and severe tensile constraint, such that (1) the state of …
ASTM E384 – Standard Test Method for Microindentation Hardness of Materials Description: Significance and Use 5.1 Hardness tests have been found to be very useful for materials evaluation, quality control of manufacturing processes and research and development efforts. Hardness, although empirical in nature, can be correlated to tensile strength for many metals and alloys, and is …
ASTM E289 – Standard Test Method for Linear Thermal Expansion of Rigid Solids with Interferometry Description: Significance and Use 5.1 Coefficients of linear expansion are required for design purposes and are used particularly to determine thermal stresses that can occur when a solid artifact composed of different materials may fail when it is subjected to a …
ASTM E228 – Standard Test Method for Linear Thermal Expansion of Solid Materials With a Push-Rod Dilatometer Description: Significance and Use 5.1 Coefficients of linear thermal expansion are required for design purposes and are used, for example, to determine dimensional behavior of structures subject to temperature changes, or thermal stresses that can occur and cause failure …
ASTM E132 – Standard Test Method for Poisson’s Ratio at Room Temperature Description: Significance and Use 4.1 When uniaxial force is applied to a solid, it deforms in the direction of the applied force, but also expands or contracts laterally depending on whether the force is tensile or compressive. If the solid is homogeneous and isotropic, …
