ASTM C773 – Standard Test Method for Compressive (Crushing) Strength of Fired Whiteware Materials Description: Significance and Use 3.1 Resistance to compression is the measure of the greatest strength of a ceramic material. Ideally, ceramics should be stressed this way in use. This test is a measure of the potential load-bearing usefulness of a ceramic. Scope …
ASTM C769 – Standard Test Method for Sonic Velocity in Manufactured Carbon and Graphite Materials for Use in Obtaining an Approximate Value of Young’s Modulus Description: Significance and Use 5.1 Sonic velocity measurements are useful for comparing materials with similar elastic properties, dimensions, and microstructure. 5.2 Eq 1 provides an accurate value of Young’s modulus only for isotropic, …
ASTM C767 – Standard Test Method for Thermal Conductivity of Carbon Refractories Description: Significance and Use 3.1 The thermal conductivity of carbon refractories is a property required for selecting their thermal transmission characteristics. Users select carbon refractories to provide specified conditions of heat loss and cold-face temperature without exceeding the temperature limitation of the carbon refractory. …
ASTM C765 – Standard Test Method for Low-Temperature Flexibility of Preformed Tape Sealants Description: Significance and Use 5.1 Preformed tape sealants are tacky, deformable solids that are used under compression between two substrates in a variety of sealing applications. This procedure is not intended to simulate an actual use condition, but it will give some indication …
ASTM C748 – Standard Test Method for Rockwell Hardness of Graphite Materials Description: Significance and Use 4.1 A Rockwell L scale hardness number is a number derived from the net increase in depth of impression as the load on a 6.3500 mm ± 0.0025 mm diameter steel-ball indenter is increased from a fixed 10 kg minor load to a …
ASTM C739 – Standard Specification for Cellulosic Fiber Loose-Fill Thermal Insulation Description: Abstract This specification covers the composition and physical requirements of chemically treated, recycled cellulosic fiber loose-fill type thermal insulation for installation in attics or enclosed spaces in housing and other buildings by pneumatic or pouring method. While the products are used in various …
ASTM C734 – Standard Test Method for Low-Temperature Flexibility of Latex Sealants After Artificial Weathering Description: Significance and Use 5.1 This test evaluates the flexibility of artificially weathered latex sealants in a low-temperature environment. Scope 1.1 This test method covers a laboratory procedure for the determination of low-temperature flexibility of latex sealants after 500 h artificial weathering. …
ASTM C730 – Standard Test Method for Knoop Indentation Hardness of Glass Description: Significance and Use 4.1 The Knoop indentation hardness is one of many properties that is used to characterize glasses. Attempts have been made to relate Knoop indentation hardness to tensile strength, grinding speeds, and other hardness scales, but no generally accepted methods are …
ASTM C719 – Standard Test Method for Adhesion and Cohesion of Elastomeric Joint Sealants Under Cyclic Movement (Hockman Cycle) Description: Significance and Use 5.1 The failure of a building sealant in an active joint is usually manifested by cohesive failure in the sealant or adhesive failure between the sealant and the substrate, or both. The method …
ASTM C704 – Standard Test Method for Abrasion Resistance of Refractory Materials at Room Temperature Description: Significance and Use 4.1 This test method measures the relative abrasion resistance of various refractory samples under standard conditions at room temperature. 4.2 The abrasion resistance of a refractory material provides an indication of its suitability for service in abrasive environments. …
