1、Designation: D5451 93 (Reapproved 2016)Standard Practice forSampling Using a Trier Sampler1This standard is issued under the fixed designation D5451; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A numb

2、er in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers sampling using a trier. A trierresembles an elongated scoop as shown in Fig. 1. The trier isused to collect samples of

3、 granular or powdered materials thatare moist or sticky and have a particle diameter less thanone-half the diameter of the trier.1.2 The trier can be used as a vertical coring device onlywhen it is certain that a relatively complete and cylindricalsample can be extracted.1.3 This standard does not p

4、urport to address all of thesafety problems, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Summary of Practic

6、e3.1 As a coring device, the trier is pushed into the materialto be sampled and is turned to cut the core. The core is thenremoved from the hole.4. Significance and Use4.1 This practice is applicable to sampling soils and similarfine-grained cohesive materials. This practice is to be used bypersonne

7、l who are to acquire the samples.4.2 This practice should be used in conjunction with GuideD4687, which covers sampling plans, safety, quality assurance,preservation, decontamination, labeling, and chain-of-custodyprocedures; Practice D5088, which covers the decontaminationof field equipment used at

8、 waste sites; and Practice D5283,which covers project specifications and practices for environ-mental field operations.5. Sampling Equipment5.1 The trier should be made from materials that arecompatible with the substances being sampled and with thetests or analyses to be performed. Either stainless

9、 steel orpolytetrafluoroethylene-coated metal will be suitable for mostsituations (see Fig. 1).6. Sample Containers6.1 Plastic, glass, or other nonreactive containers should beused. Refer to Guide D4687 for further information on con-tainers.7. Procedure7.1 Record appropriate information and observa

10、tions on thesample location.7.2 If sampling soils, remove surface vegetation or debris,or both, from the area of sample extraction.7.3 For core sampling, proceed as follows:7.3.1 Insert the trier approximately perpendicular to thesurface of the material and rotate (one or two times) to cut acore.7.3

11、.2 Pull the core out of the hole slowly. Do not allowadditional overburden material to become part of the sample.Inspect the core surface, and note the appearance of anyirregularities (for example, scratches, pock marks, andpebbles). Also inspect the core for breakage. If breakage hasoccurred and th

12、e core does not satisfy minimum lengthrequirements, discard it and extract another from an immedi-ately adjacent location.7.4 Transfer the sample into a suitable container using aclean spatula. Seal the container and affix a label.7.5 Complete the field logbook and chain-of-custody forms.7.6 Deconta
