ASTM D6773-08<\/h3>\n

Historical Standard: Standard Shear Test Method for Bulk Solids Using the Schulze Ring Shear Tester<\/h4>\n
\n

ASTM D6773<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers the apparatus and procedures for measuring the unconfined yield strength of bulk solids during both continuous flow and after storage at rest. In addition, measurements of internal friction, bulk density, and wall friction on various wall surfaces are included.<\/p>\n

1.2 The most common use of this information is in the design of storage bins and hoppers to prevent flow stoppages due to arching and ratholing, including the slope and smoothness of hopper walls to provide mass flow. Parameters for structural design of such equipment may also be derived from this data. Another application is the measurement of the flowability of bulk solids, for example, for comparison of different products or optimization.<\/p>\n

1.3 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D 6026.<\/p>\n

1.3.1 The procedures used to specify how data are collected\/recorded or calculated in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user\u2019<\/span>s objectives: and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.<\/p>\n

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/span><\/p>\n
