More D They may be used for any purpose where disturbed samples can be used and are valuable in connection with groundwater level determination and indication of changes in strata and advancement of hole for split-barrel penetration tests and sampling Test Method D and thin-walled tube sampling Practice D Equipment required is simple and readily available.

Depths of auger explorations are, however, limited by groundwater conditions, soil characteristics, and the equipment used. Scope 1. This practice does not apply to hollow-stem augers.

Uses of hollow-stem auger drilling methods for geotechnical exploration are addressed in Test Method D Samples recovered from this standard are considered as belonging to Group A or B in accordance with D The samples are disturbed and can generally be used for classification testing D, D , determination of compaction characteristics D, D , or any other standard that requires bulk samples.

For obtaining intact samples use of thin-walled sample tubes D in conjunction with fluid rotary drilling D or hollow-stem augers D may be considered. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard 1. 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.

Golrajas Non-SI units given in parentheses are for information only. However, this equilibrium and the related liquid and vapor concentrations can vary greatly depending on temperature and the chemical composition of the liquid phase. Hydrogen sulfide H 2 S is a very dangerous, toxic, explosive and flammable, colorless and transparent gas which can be found in crude oil and can be formed during the manufacture of the fuel at the sstm and can be released during handling, storage, and distribution. H2S Analyser However, at higher concentrations, it causes a loss of smell, headaches, and dizziness, and at very high concentrations, it causes instantaneous death. Specification fuels falling within the scope of this test method are: However it does not necessarily simulate the vapor phase H 2 S concentration of a fuel storage tank nor does it provide any indication of the liquid phase H 2 S concentration.
