This European Standard describes a method for the determination of the boiling range distribution of petroleum products by capillary gas chromatography using flame ionisation detection. The standard is applicable to crude oils. The boiling range distribution and recovery to C100 or C120 can be determined.
Two procedures are described: single and dual analysis mode. The basis of each is the calculation procedure as described in Annex A.
NOTE 1   This standard does not purport to address all of th...

This document 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. This document also gives guidance on the assessment
of bias.

This document specifies a gas-chromatographic method for the identification and quantification of organotin compounds (OTCs) in soils as specified in Table 1.
This document is also applicable to samples from sediments, sludges and wastes (soil-like materials).
The working range depends on the detection technique used and the amount of sample taken for analysis.
The limit of quantification for each compound is about 10 μg/kg.      
Organotin cations can only be determined in accordance with this ...

This document specifies a general method for determining the average molecular mass and molecular
mass distribution of polymers (see Reference [1]) from 2 000 g ⋅ mol−1 to 20 000 g ⋅ mol−1 by matrixassisted
laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS).
The average molecular masses and molecular mass distributions are calculated from a calibration
curve constructed using synthetic-polymer and/or biopolymer standards. This method is therefore
classified as a rel...

This European Standard specifies the quantitative determination of 16 polycyclic aromatic hydrocarbons (PAH) (see Table 2) in sludge, soil and treated biowaste using GC-MS and HPLC-UV-DAD/FLD covering a wide range of PAH contamination levels (see also Annex B).
When using fluorescence detection, acenaphthylene cannot be measured.

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).
