It is not possible to buy in the shop – please contact us. This design was used to recover sand samples that tend to run out of the tube with sampler withdraw. For determination of undrained strength, unconfined compression or unconsolided, undrained triaxial compression tests are often used Test Methods D and D The tubes are d157 usually supplied with a machine-beveled inside cutting edge which provides the Clearance Ratio C r.

Sands are much more difficult to penetrate and may require use of asgm diameter tubes. Cutting edge angles of up to 20 to 30 degrees have been used in stiffer formations in order to avoid damage to the cutting edges. For information on appropriate use of other soil samplers refer to Practice D This sampling method is not recommended for asrm soils containing gravel or larger size soil particles cemented or very hard soils. The most commonly used tube is the 3-in.

Longer time periods may be allowed depending on logistics and the quality assurance requirements of the exploration plan. Any drilling method that ensures the base of the borehole is intact and that the borehole walls are stable may be used. 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. The push equipment should provide a smooth continuous vertical push.

A piston sampler Practice D must be used to ensure that there is no fluid or sidewall contamination that would enter an open sampling tube. Use of metric equivalent is acceptable as long as thickness and proportions are similar to those required in this standard.

Such samplers include driven split barrel samplers and soil coring devices D, D, and D For information on appropriate use of other soil samplers refer to Practice D However, if this practice is used properly, soil samples suitable for laboratory testing can be procured. Such samplers include driven split barrel samplers and soil coring devices Test Methods D, D, and Practice D Kontakt venligst Dansk Standard.

Subsurface geotechnical explorations should be reported in accordance with practice D For information on appropriate use of other soil samplers refer to D Consolidation test specimens are generally larger diameter than those for strength testing and larger diameter soil cores may be required.

Wall thickness may be changed 5. For information on preservation and transportation process of soil samples, consult Practice D The piston sampler Practice D uses a thin-walled tube.

Historical Version s – view previous versions of standard. Dd1587 sample depth of the sampler should coincide with the drilled depth. If samples are taken in uncased boreholes the cores should be inspected for any sidewall contamination. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Users of this practice are cautioned that compliance with Practice D does not in itself ensure reliable results.

The recommended combinations of A rcutting angle, and C d15587 are given below also see 6.

Lengths of tubes shown are illustrative. Link to Active D11587 link will always route r1587 the current Active version of the standard. Extruded cores can be preserved by encasing the cores in plastic wrap, tin foil, and then d15877 wax to preserve moisture.

For softer or harder soils C r tubes may require special order from the supplier. The tubing tolerances presented in are from sources available in North America. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. Other soil samplers may be used for sampling these soil types. Subsurface geotechnical explorations should be reported in accordance with Practice D While the sample and push lengths are shorter than the tube, see 7.

Note This practice does not apply to liners used within the samplers.
