1、Designation: D 5451 93 (Reapproved 2008)Standard Practice forSampling Using a Trier Sampler1This standard is issued under the fixed designation D 5451; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A nu
2、mber 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
3、of 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
4、 purport 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 Pr
6、actice3.1 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 byper
7、sonnel who are to acquire the samples.4.2 This practice should be used in conjunction with GuideD 4687, which covers sampling plans, safety, quality assur-ance, preservation, decontamination, labeling, and chain-of-custody procedures; Practice D 5088, which covers the decon-tamination of field equip
8、ment used at waste sites; and PracticeD 5283, which covers project specifications and practices forenvironmental 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. Eithe
9、r stainless steel orpolytetrafluoroethylene-coated metal will be suitable for mostsituations (see Fig. 1).6. Sample Containers6.1 Plastic, glass, or other nonreactive containers should beused.

Procedure7.1 Record appropriate information and observations 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 appr
13、oximately perpendicular to thesurface of the material and rotate (one or two times) to cut acore.7.3.2 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, sc
14、ratches, pock marks, andpebbles). Also inspect the core for breakage. If breakage hasoccurred and the 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 t
15、he container and affix a label.7.5 Complete the field logbook and chain-of-custody forms.7.6 Decontaminate the used equipment in accordance withPractice D 5088.8.
