ASTM C794 – Standard Test Method for Adhesion-in-Peel of Elastomeric Joint Sealants Description: Significance and Use 5.1 There are differences in opinion among those concerned with sealant technology whether or not this adhesion-in-peel test simulates the type of strain and e-tensile stresses encountered by a sealant in normal use. Nevertheless, this test provides a valuable measurement …
ASTM C793 – Standard Test Method for Effects of Laboratory Accelerated Weathering on Elastomeric Joint Sealants Description: Significance and Use 5.1 It is known that solar radiation contributes to the degradation of sealants in exterior building joints. The use of a laboratory accelerated weathering machine with actinic radiation, moisture and heat appears to be a feasible …
ASTM C791 – Standard Test Methods for Chemical, Mass Spectrometric, and Spectrochemical Analysis of Nuclear-Grade Boron Carbide Description: Significance and Use 4.1 Boron carbide is used as a control material in nuclear reactors. In order to be suitable for this purpose, the material must meet certain criteria for assay, isotopic composition, and impurity content. These methods …
ASTM C786 – Standard Test Method for Fineness of Hydraulic Cement and Raw Materials by the 300-μm (No. 50), 150-μm (No. 100), and 75-μm (No. 200) Sieves by Wet Methods Description: Abstract This test method covers wet sieving techniques for determination of fineness of hydraulic cement and raw materials by means of the No. 50, …
ASTM C780 – Standard Test Methods for Preconstruction and Construction Evaluation of Mortars for Plain and Reinforced Unit Masonry Description: Significance and Use 5.1 During preconstruction and construction evaluations, use of these test methods establishes specific and overall performance characteristics for the mortar system. 5.2 Preconstruction testing of mortars prebatched by weight provides information for the selection …
ASTM C78 – Standard Test Method for Flexural Strength of Concrete (Using Simple Beam with Third-Point Loading) Description: Significance and Use 4.1 This test method is used to determine the flexural strength of specimens prepared and cured in accordance with Test Methods C42/C42M or Practices C31/C31M or C192/C192M. Results are calculated and reported as the modulus of rupture. For the same …
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 …
