Description of ASTM-D4380 2012ASTM D4380 - 12Standard Test Method for Density of Bentonitic SlurriesActive Standard ASTM D4380 | Developed by Subcommittee: D18.04 Book of Standards Volume: 04.08 ASTM D4380Significance and Use 5.1 This test method is used to determine the density of bentonitic slurries in the laboratory and field. For freshly mixed slurry, this test method may be used as an indicator of mix proportions. For in-trench slurry, a certain value may be specified for maintaining trench stability.
Note 1 The quality of the result produced by this standard depends on the competence of the personnel performing
it and the suitability of the equipment and facilities being used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing,
sampling, inspection, etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself ensure reliable results. Reliable results depend on many factors;
Practice D3740 provides a means of evaluating some of those factors.
1. Scope 1.1 This test method covers the determination of the density of slurries used in slurry construction techniques, such as those used for barriers to control the horizontal movement of liquids. This test method is modified from API Recommended Practice?13B . 1.2 Units The values stated in SI units are to be regarded as standard, unless other units are also specified, such as density in lbm/ft 3 or lbm/gal. No other units of measurement are included in this standard. 1.3 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.
