ASTM D70 – Standard Test Method for Specific Gravity and Density of Semi-Solid Asphalt Binder (Pycnometer Method) Description: Significance and Use 5.1 Values of density are used for converting volumes to units of mass, and for correcting measured volumes from the temperature of measurement to a standard temperature using Practice D4311/D4311M. 5.2 The quality of the results produced …
ASTM D56 – Standard Test Method for Flash Point by Tag Closed Cup Tester Description: Significance and Use 5.1 Flash point measures the tendency of the specimen to form a flammable mixture with air under controlled laboratory conditions. It is only one of a number of properties that shall be considered in assessing the overall flammability …
ASTM C1702 – Standard Test Method for Measurement of Heat of Hydration of Hydraulic Cementitious Materials Using Isothermal Conduction Calorimetry Description: Significance and Use 5.1 This method is suitable for determining the total heat of hydration of hydraulic cement at constant temperature at ages up to 7 days to confirm specification compliance. 5.2 This method compliments Practice C1679 by …
ASTM C1602 – Standard Specification for Mixing Water Used in the Production of Hydraulic Cement Concrete Description: Abstract This specification covers mixing water used in the production of hydraulic cement concrete. It defines sources of water and provides requirements and testing frequencies for qualifying individual or combined water sources. Mixing water shall consist of: batch …
ASTM C1549 – Standard Test Method for Determination of Solar Reflectance Near Ambient Temperature Using a Portable Solar Reflectometer Description: Significance and Use 5.1 The temperatures of opaque surfaces exposed to solar radiation are generally higher than the adjacent air temperatures. In the case of roofs or walls enclosing conditioned spaces, increased inward heat flows result. …
ASTM C1499 – Standard Test Method for Monotonic Equibiaxial Flexural Strength of Advanced Ceramics at Ambient Temperature Description: Significance and Use 4.1 This test method may be used for material development, material comparison, quality assurance, characterization, and design code or model verification. 4.2 Engineering applications of ceramics frequently involve biaxial tensile stresses. Generally, the resistance to equibiaxial …
ASTM C1421 – Standard Test Methods for Determination of Fracture Toughness of Advanced Ceramics at Ambient Temperature Description: Significance and Use 5.1 Fracture toughness, KIc, is a measure of the resistance to crack extension in a brittle material. These test methods may be used for material development, material comparison, quality assessment, and characterization. 5.2 The pb and the …
ASTM C1371 – Standard Test Method for Determination of Emittance of Materials Near Room Temperature Using Portable Emissometers Description: Significance and Use 5.1 Surface Emittance Testing: 5.1.1 Heat transfer from a surface by radiation transfer is reduced if the surface of a material has a low emittance. Since the controlling factor in the use of insulation is …
ASTM C1350 – Standard Test Method for Measurement of Viscosity of Glass Between Softening Point and Annealing Range (Approximately 108 Pa·s to Approximately 1013 Pa·s) by Beam Bending (Metric) Description: Significance and Use 4.1 This test method is well suited for measuring the viscosity of glasses in ranges higher than those covered by parallel plate (see Test Method C1351M) …
ASTM C1327 – Standard Test Method for Vickers Indentation Hardness of Advanced Ceramics Description: Significance and Use 5.1 For advanced ceramics, Vickers indenters are used to create indentations whose surface-projected diagonals are measured with optical microscopes. The Vickers indenter creates a square impression from which two surface-projected diagonal lengths are measured. Vickers hardness is calculated from …
