1.1 This practice covers the selection, packaging, preservation, transportation, reception, storage, cataloguing, retrieval, preparation for laboratory testing and post-test disposition of frozen samples of soils and rocks obtained from regions of intermittent and continuous perennially frozen ground (that is, permafrost). 1.2 This practice applies to samples of frozen soils, frozen friable rocks, and frozen soft and hard rocks. The ground ice in the samples may be visible or invisible and vary in content from ice-poor (with just sufficient ice to bond the soil particles) to ice-rich (ground ice with entrapped soil). Frozen friable samples, with insufficient ice to provide a frozen bond, are known as dry permafrost. 1.3 Units--The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.4 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.
Keywordsfrozen soil samples; frozen soil rock samples; handling; transportation; storage; preparing for laboratory testing
Laboratory test results for frozen soil and rock samples depend on the disturbance and thermal and moisture regimes of the samples. To obtain standardized test results, the handling, transportation, storage and preparation for laboratory testing of the frozen soil and rock samples need to be standardized as well.
