This document specifies a test method for the determination of the content of mono-aromatic, di-aromatic and tri+-aromatic hydrocarbons in diesel fuels, paraffinic diesel fuels and petroleum distillates.
This document defines two procedures, A and B.
Procedure A is applicable to diesel fuels that may contain fatty acid methyl esters (FAME) up to 30 % (V/V) (as in [1], [2] or [3]) and petroleum distillates in the boiling range from 150 °C to 400 °C (as in [4].
Procedure B is applicable to paraffinic diesel fuels with up to 7 % (V/V) FAME. This procedure does not contain a dilution of the sample in order to determine the low levels of aromatic components in these fuels.
The polycyclic aromatic hydrocarbons content is calculated from the sum of di-aromatic and tri+-aromatic hydrocarbons and the total content of aromatic compounds is calculated from the sum of the individual aromatic hydrocarbon types.
Compounds containing sulfur, nitrogen and oxygen can interfere in the determination; mono-alkenes do not interfere, but conjugated di-alkenes and poly-alkenes, if present, can do so.
NOTE 1 For the purpose of this European Standard, the terms "% (m/m)" and "% (V/V)" are used to represent the mass fraction, µ, and the volume fraction, φ, of a material respectively.
NOTE 2 By convention, the aromatic hydrocarbon types are defined on the basis of their elution characteristics from the specified liquid chromatography column relative to model aromatic compounds. Their quantification is performed using an external calibration with a single aromatic compound for each of them, which may or may not be representative of the aromatics present in the sample. Alternative techniques and test methods may classify and quantify individual aromatic hydrocarbon types differently.
NOTE 3 Backflush is part of laboratory-internal maintenance.

This part of IEC 62321 specifies two different techniques for the determination of
tris(2-chloroethyl) phosphate (TCEP) in plastics, the GC-MS or LC-MS method, both of which
are applicable to quantitative analysis.
These two techniques are applicable to use with polyurethane, polyvinylchloride, and
polyethylene materials containing TCEP between 200 mg/kg to 2 000 mg/kg.
These test methods do not apply to plastic materials having a processing temperature higher
than 230 °C.
GC-MS using a pyrolyser/thermal desorption accessory (Py/TD-GC-MS) technique is described
in Annex A and can be used for the screening of TCEP in plastics.
NOTE TCEP starts thermal decomposition at approximately 230 °C. Polymer types that have a processing
temperature into shapes of plastics (e.g. pellets, moulded parts or sheets) not exceeding the decomposition
temperature can contain TCEP.

X-ray Fluorescence Spectrometry (XRF) has been used for several decades as an important analytical tool for production analysis. XRF is characterised by its speed and high precision over a wide concentration range and since the technique in most cases is used as an relative method the limitations are often connected to the quality of the calibration samples. The technique is well established and most of its physical properties are well known.

The limit of detection depends on the determinants, the equipment used, the quality of chemicals used for the extraction of the sample and the clean-up of the extract
Under the conditions specified in this European Standard, lower limit of application from 10 μg/kg (expressed as dry matter) for soils, sludge and biowaste to 100 μg/kg (expressed as dry matter) for solid waste can be achieved. For some specific samples (e.g. bitumen) the limit of 100 μg/kg cannot be reached.
Sludge, waste and treated biowaste may differ in properties as well as in the expected contamination levels of PAH and presence of interfering substances. These differences make it impossible to describe one general procedure. This European Standard contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used.
The method may be applied to the analysis of other PAH not specified in the scope, provided suitability is proven by proper in-house validation experiments.

This International Standard specifies the measurement of explosive and related nitrocompounds
compounds using liquid chromatography–tandem mass spectrometry (LC-MS/MS) in soil and soilmaterials. This method is applicable to 12 compounds (1,3-DNB, 1,3,5-TNB, 2,4-DNT, 2,6-DNT, 2,4,6-TNT, 4-A-2,6-DNT, 2-A-4,6-DNT, Tetryl, Hexyl, RDX, HMX, PETN) listed in ISO 11916-1(soil, HPLC/UV method) except nitrobenzene, 2-nitortoluene, 3-nitrotoluene and 4-nitrotoluene. In particular,this method is effective for the analysis of PETN, 1,3,5-TNB and tetryl which showed poor interlaboratory trial results with ISO 11916-1. Under the conditions specified in this document, concentrations as low as 0,005 mg/kg to 0,014 mg/kg-dry matter can be determined, depending on the substance.
Purpose and justification of the proposal*
Currently two ISO standards exist for the analysis of explosives and related compounds in soil: ISO 11916-1(HPLC/UV method), ISO 11916-2(GC-ECD or MS method). According to the results of interlaboratory trial with ISO 11916-1, it showed some problematic aspects to analyze PETN, 1,3,5-TNB and tetryl. In case of ISO 11916-2, it also gave poor inter-laboratory trial results for 1,3,5-TNB. Therefore, it is necessary to develop new method effectively applicable to the determination of PETN, 1,3,5-TNB and tetryl.
In addition to this, lower risk-based PRGs (Preliminary Remediation Goal), new regulatory concerns, and change of land use have created the atmosphere to apply more sensitive and selective instruments to determine explosive and related compounds. From the view of these aspects, liquid chromatography–tandem mass spectrometry (LC-MS/MS) is one of alternative methods for these purposes. LC-MS/MS method provides 10-20 times or much lower detection limit than that of HPLC/UV method and is recommendable to determine PETN, 1,3,5-TNB and tetryl.
Also LC-MS/MS method is getting more familiar in ISO standard development (e.g. ISO/CD22104 Water quality--Microcystins, ISO/NP21677 Water quality--HBCD, ISO/CD21675 Water quality--PFAS).
Consider the following: Is there a verified market need for the proposal? What problem does this
standard solve? What value will the document bring to end-users? See Annex C of the ISO/IEC
Directives part 1 for more information. See the following guidance on justification statements on ISO Connect:

The proposed standard aims at describing a method to analyze 57 chemically defined suspected allergens (some of them existing under several isomeric forms or as mixtures) in ready to inject fragrance and raw material samples according to the SCCS opinion. (SCCS/1459/11).
This new analytical method uses gas chromatography and mass spectrometry (GC-MS) to detect and to quantify the 57 fragrance substances and their relevant isomers at a concentration higher than 0.0002% (2 mg/kg) in ready to inject fragrance and raw material samples. Making this method available will allow the screening of (complex) ready to inject fragrance and raw material samples to be undertaken for the presence of any of those chemically defined suspected allergens. It will therefore be a basis for the calculation of adequate information to the cosmetics industry in order to provide adequate consumer information. The present analytical method uses GC-MS by combination of two GC columns of different polarity with a dedicated methodology for quantitation.

This part of IEC 62321 provides strategies of sampling along with the mechanical preparation
of samples from electrotechnical products. These samples can be used for analytical testing to
determine the levels of certain substances as described in the test methods in other parts of
the IEC 62321 series. Restrictions for substances will vary between geographic regions and
can be updated on a regular basis. This document describes a generic process for obtaining
and preparing samples prior to the determination of any substance of concern.
This document does not provide:
– full guidance on each and every product that could be classified as electrotechnical product.
Since there is a huge variety of electrotechnical parts, with various structures and
compositions, along with the continuous innovations in the industry, it is unrealistic to
attempt to provide procedures for the disjointment of every type of part;
– guidance regarding other routes to gather additional information on certain substances in a
product, although the information collected has relevance to the sampling strategies in this
document;
– safe disassembly and mechanical disjointment instructions related to electrotechnical
products (e.g. mercury-containing switches) and the recycling industry (e.g. how to handle
CRTs or the safe removal of batteries). See IEC 62554 [1] 1 for the disjointment and
mechanical sample preparation of mercury-containing fluorescent lamps;
– sampling procedures for packaging and packaging materials;
– analytical procedures to measure the levels of certain substances. This is covered by other
standards (e.g. other parts of the IEC 62321 series), which are referred to as "test
standards" in this document;
– guidelines for assessment of compliance.
This document has the status of a horizontal standard in accordance with IEC Guide 108 [2].

0,50 % (V/V) up to 17,86 % (V/V); a total volume of MTBE from 0,99 % (V/V) up to 15,70 % (V/V), a total
volume of ETBE from 0,99 % (V/V) up to 15,49 % (V/V), a total volume of TAME from 0,99 % (V/V) up to
5,92 % (V/V), and a total volume of TAEE from 0,98 % (V/V) up to 15,59 % (V/V).
Although this test method can be used to determine higher-olefin contents of up to 50 % (V/V), the
precision for olefins was tested only in the range from 0,40 % (V/V) to 26,85 % (V/V).
Although specifically developed for the analysis of automotive motor gasoline that contains oxygenates,
this test method can also be applied to other hydrocarbon streams having similar boiling ranges, such
as naphthas and reformates.
NOTE 2 For Procedure A, applicability of this document has also been verified for the determination of
n-propanol, acetone, and di-isopropyl ether (DIPE). However, no precision data have been determined for these
compounds.
Procedure B describes the analysis of oxygenated groups (ethanol, methanol, ethers, C3 – C5 alcohols)
in ethanol (E85) automotive fuel containing ethanol between 50 % (V/V) and 85 % (V/V). The gasoline
is diluted with an oxygenate-free component to lower the ethanol content to a value below 20 % (V/V)
before the analysis by GC.
The sample can be fully analysed including hydrocarbons. Precision data for the diluted sample are
only available for the oxygenated groups.
NOTE 3 For Procedure B, the precision can be used for an ethanol fraction from about 50 % up to 85 % (V/V).
For the ether fraction, the precision as specified in Table 6 can be used for samples containing at least 11 % (V/V)
of ethers. For the higher alcohol fraction, too few data were obtained to derive a full precision statement and the
data presented in Table 6 are therefore only indicative.
NOTE 4 An overlap between C9 and C10 aromatics can occur. However, the total is accurate. Isopropyl benzene
is resolved from the C8 aromatics and is included with the other C9 aromatics.

This European Standard specifies a method for quantitative determination of seven selected polychlorinated biphenyls (PCB28, PCB52, PCB101, PCB118, PCB138, PCB153 and PCB180) in soil, sludge, sediment, treated biowaste and waste and using GC-MS and GC-ECD.
The limit of detection depends on the determinants, the equipment used, the quality of chemicals used for the extraction of the sample and the clean-up of the extract.
Under the conditions specified in this European Standard, lower limit of application from 1 μg/kg (expressed as dry matter) for soils, sludge and biowaste to 10 μg/kg (expressed as dry matter) for solid waste can be achieved. For some specific samples the limit of 10 μg/kg cannot be reached.
Sludge, waste and treated biowaste may differ in properties, as well as in the expected contamination levels of PCBs and presence of interfering substances. These differences make it impossible to describe one general procedure. This European Standard contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used.
NOTE For the analysis of PCB in insulating liquids, petroleum products, used oils and aqueous samples is referred to EN 61619, EN 12766–1 and EN ISO 6468 respectively.
The method may be applied to the analysis of other PCB congeners not specified in the scope, provided suitability is proven by proper in-house validation experiments
