Standard Test Method for Field Determination of Apparent Specific Gravity of Rock and Manmade Materials for Erosion Control — 3 стр.
Значение и использование

Specific gravity is one factor used to determine the required mass of individual particles used as gabion-fill, riprap, armor stone, breakwater stone, or other types of rock products used for erosion control applications, and acceptibility of these materials for their intended use.

Note 1—The agency performing this test method can be evaluated in accordance with Practice D3740. Not withstanding statements on precision and bias contained in this test method: The precision of this test method is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing. Users of this test method are cautioned that compliance with D3740 does not in itself ensure reliable testing. Reliable testing depends on many factors; Practice D3740 provides a means of evaluating some of those factors.

Область применения

1.1 This test method covers the determination of the specific gravity of rock or man-made materials for erosion control.

1.2 This is a field test method to measure apparent specific gravity. For laboratory determination of bulk specific gravity see Test Method D6473.

1.3 UnitsThe values stated in SI units are to be regarded as the standard. The inch-pound units in parentheses are given for information only.

1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.

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.
