ASTM D Standard

For construction control, these test methods are often used as the bases for acceptance of material compacted to a specified density or to a percentage of a maximum unit weight determined by a standard laboratory test method such as determined from Test Method D or Dsubject to the limitations discussed in 1. Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. In addition they are representative of the significant digits that generally should be retained.

It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

Users of these test methods are cautioned that compliance with Practice D does not in itself ensure reliable results.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The d494 of the test methods may be affected for materials that deform easily or that may undergo volume change in the excavated hole from standing or walking near the hole during the test. Test Method A can also be used to determine percent compaction or percent relative density when the maximum particle size present in the in-place material being tested does not exceed the maximum particle size allowed in the laboratory compaction test refer to Test Methods D d914, DDand D For specific hazards statements, see Sections 8 and A1.

While the equipment illustrated in these test methods is used for volumes less than 0. Then the material is considered to consist of two fractions, or portions. Please choose number of devices you want to open the document on. awtm

The material from the in-place unit weight test dd4914 physically divided into a control fraction and an oversize fraction based on a designated sieve size. In general, the materials tested would have a maximum particle size of 75 to mm [3 to 5 in. For specific hazards statements, see Sections 7 and A1. Continue shopping Proceed to checkout. However, for larger sized excavations, Test Method D is preferred.

The unit weight of the control fraction is calculated and compared with the astj weight s established by the laboratory atm test s. While the equipment illustrated in these test methods is used for volumes less than 1 ft 0. It is undesirable to combine the use of two separate systems within a single standard. Link to Active This link will always route to the current Active version of the standard. This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system.

For Test Methods D and D only, the unit weight determined in the laboratory compaction test may be corrected asmt larger particle sizes in accordance with, and subject to the limitations of Practice D The printed version is available at half price when you buy the electronic version. Test Method A can also be used to determine percent compaction or percent relative density when the maximum particle size present in the in-place material being tested does not exceed the maximum particle size allowed in the laboratory compaction test refer to Test Methods DD494DDand D It is not possible to buy in the shop – please contact us.

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. For Test Methods D and D only, the dry density determined in d4941 laboratory compaction test may be corrected for larger particle sizes in accordance with, and subject to the limitations of Practice D In general, the materials tested would have a maximum particle size of 3 to 5 in.

The values stated in each system may not be exact equivalents; therefore each system shall be used independently of aastm other. Du abonnerer allerede dette emne.

It should also be firm enough not to deform or slough due to the minor pressures exerted in digging the hole and pouring the sand. Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing. Test Method A can also be used to determine percent compaction or percent relative density when the maximum particle size present in the in-place material being tested does not exceed the maximum particle size allowed in the laboratory compaction test refer to Test Methods D, D, D, and D This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system.

It should also be firm enough not to deform or slough due to the minor pressures exerted in digging the hole and pouring the sand. Link to Active This link will always route to the current Active version of the standard.

The dry density of the control fraction is calculated and compared with the dry density s established by the laboratory compaction test s. Active view current version of standard. Combining values from the two systems may result in non-conformance with the standard. Do not show this ast. However, for larger sized excavations, Test Method D is preferred. Are you sure you want to unsubscribe monitoring?

The material being tested should have sufficient cohesion or particle interlocking asstm maintain stable sides during excavation of the test pit and through completion of this test. However, conversions are given in the SI system.

The word “rock” in these test methods is used to imply that the material being tested will typically contain particles larger than 3 in. Then the material is considered to consist of two fractions, or portions. It should also be firm enough not to deform or slough due to the minor pressures exerted in digging the hole and pouring the sand.
