This document specifies a micro gas chromatography method for the on-line or offline determination of the content of five terpenes in biomethane, namely: — alpha-pinene, — beta-pinene, — para-cymene, — limonene, — 3-carene. The method is specifically developed for these five compounds. Information about the compounds is given in Annex A. The method is applicable to the determination of individual amount fractions of the five terpenes from 1 µmol/mol up to and including 10 µmol/mol. With minor modifications it can also be used for terpene amount fractions above 10 µmol/mol.

This document specifies a method for the determination of drag reduction of slick water, which is mainly used to evaluate the drag reduction performance of slick water. This document uses the pipeline method to evaluate the drag reduction, which is currently recognized as the best method to evaluate the drag reduction performance. This document describes the device, experimental conditions and operating steps in detail. The drag reduction value obtained by evaluation according to this document can effectively represent the on-site drag reduction performance.

This document is applicable to the determination of the total silicon content in gaseous matrices such
as biomethane, biogas and landfill gas. Silicon is present in a gas phase contained predominantly in
siloxane compounds, trimethylsilane and trimethylsilanol. The analytical form of the silicon measured in
liquid phase after conducted sampling and derivatization procedure is soluble hexafluorosilicate anion
stable in slightly acidified media. Total silicon is expressed as a mass of silicon in the volume of the
analysed gas.
This document is applicable to all stated gas matrices with silicon concentrations up to 5 mg/m3, and it
is prevalently intended for the biomethane matrices containing (0,1 to 0,5) mg/m3. It can be used for
higher concentration but then the absorption efficiency of the bubblers/impingers should be checked
before the results can be regarded as valid. The detection limit of the method is estimated as 0,05
mg/m3 based on a sample volume of 0,020 m3. All compounds present in the gas phase are volatile at
the absorption and derivatization temperature and gaseous siloxanes are trapped in absorbance media
and derivatized into analytical silicon specie are measured by this method. The concentration of the
silicon is measured in diluted derivatization media using atomic emission spectrometer upon
atomisation/ionisation in microwave or inductively coupled plasma.

This document is applicable to stated gaseous matrices with silicon concentrations up to 5 mg/m3, and it is prevalently intended for the biomethane matrices with Si mass concentration of 0,1 mg/m3 to 0,5 mg/m3.
With adaptation to ensure appropriate absorption efficiency, it can be used for higher concentrations. The detection limit of the method is estimated as 0,05 mg/m3 based on a gas sample volume of 0,020 m3. All compounds present in the gas phase are volatile at the absorption and derivatization temperature and gaseous organosilicon species are trapped in absorbance media and derivatized into analytical silicon that is measured by this method. The concentration of the silicon is measured in diluted derivatization media using atomic emission spectrometry upon atomisation/ionisation in microwave or inductively coupled plasma.
Unless specified otherwise, all volumes and concentrations refer to standard reference conditions (temperature, 273 K, and pressure, 101,325 kPa).
NOTE When using appropriate dilution factors, the method can also be applied for silicon concentrations above 5 mg/m3.

are conveyed into transmission and distribution grids are representative of the mass to which they are
allocated.
NOTE To ensure that a particular gas is taken into account in the standard, please see Annex A.
This document is applicable for sampling at sites and locations where interchangeability criteria, energy
content and network entry conditions are measured and monitored and is particularly relevant at cross
border and fiscal measurement stations. It serves as an important source for control applications in
natural gas processing and the measurement of trace components.
This document is applicable to natural dry gas (single phase - typically gas transiting through natural
gas pipelines) sampling only. On occasion a natural gas flow can have entrained liquid hydrocarbons.
Attempting to sample a wet natural gas flow introduces the possibility of extra unspecified uncertainties
in the resulting flow composition analysis. Sampling a wet gas (two or three phases) flow is outside the
scope of this document.
This document does not apply to the safety issues associated with gas sampling.

ISO 23874:2006 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 23874:2006 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).
The procedure given in ISO 23874:2006 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. 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.

This part of ISO 20765 specifies a method of calculation for the volumetric and caloric properties of natural gases, natural gases containing synthetic admixture and similar mixtures, at conditions where the mixture can exist only as a gas.
The method is applicable to pipeline-quality gases within the ranges of pressure and temperature at which transmission and distribution operations normally take place. For volumetric properties (compression factor and density), the uncertainty of calculation is about ± 0,1 % (95 % confidence interval). For caloric properties (for example enthalpy, heat capacity, Joule-Thomson coefficient, speed of sound), the uncertainty of calculation is usually greater.

This document explains an approach for assessment of limit values for contaminants that may be found
in biomethane. Limit values are generally required as an adjunct to a biomethane specification (such as
parts 1 and 2 of EN 16723, or an equivalent National specification) or as part of a Network Entry
Agreement for injection of biomethane into gas networks.
The methodology employed will permit derivation of limit values based solely on consideration of
potential for impact on human health and does not consider other impacts, such as integrity and
operation of plant and pipelines used to convey biomethane or appliances involved in its combustion or
other regulations like CLP regulation. Where consideration of such impacts would result in proposing
lower limit values than those based on health impacts, then the lowest limit values should generally be
proposed.

ISO 14469:2017 specifies CNG refuelling nozzles and receptacles constructed entirely of new and unused parts and materials, for road vehicles powered by compressed natural gas. A CNG refuelling connector consists of, as applicable, the receptacle and its protective cap (mounted on the vehicle) and the nozzle.
ISO 14469:2017 is applicable only to such devices designed for a service pressure of 20 MPa (200 bar) and 25 MPa (250 bar), to those using CNG according to ISO 15403‑1 and ISO 15403‑2 and having standardized mating components, and to connectors that prevent natural gas vehicles from being fuelled by dispensers with service pressures higher than that of the vehicle, while allowing them to be fuelled by dispensers with service pressures less than or equal to the vehicle fuel system service pressure.
ISO 14469:2017 refers to service pressures of 20 MPa and 25 MPa for:
- size 1: B200 and B250;
- size 2: C200 and C250.

ISO 14532:2014 establishes the terms, definitions, symbols, and abbreviations used in the field of natural gas.
The terms and definitions have been reviewed and studied in order to cover all aspects of any particular term with input from other sources such as European Standards from CEN (The European Committee for Standardization), national standards, and existing definitions in the IGU Dictionary of the Gas Industry.
The definitive intention of ISO 14532:2014 is to incorporate the reviewed definitions into the ISO/TC 193 source standards.
