What is ISO 23874 - Hydrocarbon dewpoint calculation in natural gas industry about? ISO 23874 is a standard covering hydrocarbon dewpoint calculation in natural gas industry, ensuring reliable repeatability of the measurements in natural gas industry applications. ISO 23874 describes the performance requirements for analysis of treated natural gas of transmission or pipeline quality in sufficient detail so that the hydrocarbon dewpoint temperature can be calculated using an appropriate equation of state. ISO 23874 is applied to gases that have maximum dewpoint temperatures (cricondentherms) between 0 °C and – 50 °C. The pressures at which these maximum dewpoint temperatures are calculated are in the range 2 MPa (20 bar) to 5 MPa (50 bar). ISO 23874 covers the measurement of hydrocarbons in the range C5 to C12. n -Pentane, which is quantitatively measured using bridge component, and all C6 and higher hydrocarbons are measured relative to n -pentane. Who is ISO 23874 - Hydrocarbon dewpoint calculation in natural gas industry f or? ISO 23874 on Hydrocarbon dewpoint calculation in natural gas industry is relevant to: Testing authorities Pipeline construction sectors Drilling engineers Hydrographic surveyors Why should you use ISO 23874 - Hydrocarbon dewpoint calculation in natural gas industry ?

What is ISO 6974-3- Determination of composition and associated uncertainty by gas chromatography about? ISO 6974-3 is the third part of the ISO 6974 multi-series that discusses natural gas. ISO 6974-3 describes the precision that can be expected from the gas chromatographic method that is set up in accordance with ISO 6974-1 . The stated precision provides values for the magnitude of variability that can be expected between test results when the method described in ISO 6974-1 is applied in one or more competent laboratories. ISO 6974-3 also gives guidance on the assessment of bias.

1.1 This practice details the collection of active soil gas samples using a variety of sample collection techniques with tooling associated with direct push drilling (DP) or manualdriven hand-sampling equipment, for the express purpose of conducting soil gas surveys. 1.2 This practice proceeds on the premise that soil gas surveys are primarily used for two (2) purposes: 1) as a preliminary site investigative tool and 2) for the monitoring of ongoing remediation activities (D7663). 1.3 The practicality of field use demands that soil gas surveys are relatively accurate, as well as being simple, quick, and inexpensive. This guide suggests that the objective of soil gas surveys is linked to three factors: 1.3.1 VOC detection and quantitation, including determination of depth of VOC contamination. 1.3.2 Sample retrieval ease and time. 1.3.3 Cost. 1.4 This practice may increase the awareness of a fundamental difference between soil gas sampling for the purpose of soil gas surveys versus sub-slab or vapor intrusion investigations or both. Specifically, the purpose of a soil gas survey is to provide quick and inexpensive data to the investigator that will allow the investigator to 1) develop a site investigation plan that is strategic in its efforts, 2) determine success or progress of on-going remedial activities, or 3) select the most suitable subsequent investigation equipment, or combinations thereof. On the other hand, the objective of soil gas sampling for sub-slab and vapor intrusion investigations is not preliminary, but rather the end result of the site investigation or long-term precise monitoring. As such, stringent sampling methods and protocol are necessary for precise samples and data collection. 1.5 Details included in this practice include a broad spectrum of practices and applications of soil gas surveys, including: 1.5.1 Sample recovery and handling, 1.5.2 Sample analysis, 1.5.3 Data interpretation, and 1.5.4 Data reporting. 1.6 Units—The values stated in either SI units or Inchpound units [given in brackets] are to be regarded separately as standard. 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. 1.7 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026. 1.7.1 The procedures used to specify how data are collected/ recorded and calculated in the standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any consideration for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering data. 1.8 This practice offers a set of instructions for performing one or more specific operations. This standard cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process. 1.9 This practice is not to be used for long term monitoring of contaminated sites or for site closure confirmation. 1.10 This practice is not to be used for passive determination of flow patterns at contaminated sites. 1.11 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the 1 This practice is under the jurisdiction of ASTM Committee D18 on Soil and Rock and is the direct responsibility of Subcommittee D18.21 on Groundwater and Vadose Zone Investigations.

This International Standard describes the performance requirements for analysis of treated natural gas of transmission or pipeline quality in sufficient detail so that the hydrocarbon dewpoint temperature can be calculated using an appropriate equation of state. It can be applied to gases that have maximum dewpoint temperatures (cricondentherms) between 0 °C and - 50 °C. The pressures at which these maximum dewpoint temperatures are calculated are in the range 2 MPa (20 bar) to 5 MPa (50 bar). Major components are measured using ISO 6974 (all parts) and the ranges of components that can be measured are as defined in ISO 6974-1. The procedure given in this International Standard covers the measurement of hydrocarbons in the range C5 to C12. n-Pentane, which is quantitatively measured using ISO 6974 (all parts), is used as a bridge component and all C6 and higher hydrocarbons are measured relative to n-pentane.
