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

This document establishes a valid method for separation of chemically heterogeneous polyethylene oxide (PEO) mixtures and for the determination the number and content of the chemically heterogeneous species in the overall sample. The method presented in this document serves as a technical guideline and enables laboratories to learn the principle of "critical chromatography" on a validated system. This method presented in this document with its stated system parameters is not applicable for other polymer classes, due to the diversity of the interactions between the polymer/mobile phase/stationary phase and the number of separation systems that are therefore available. The evaluation of the interlaboratory testing has shown that many error sources relate to the technique of liquid chromatography in general. Possible error sources are described in Annex A. Details on the evaluation of the interlaboratory testing are given in Annex B. Elugrams of the participants (excerpts) are given in Annex C. Investigations of the long-term stability of the test mixture are given in Annex D.

This document is applicable for the determination of VOC and SVOC with an expected VOC and/or SVOC content greater than 0,01 % by mass up to 100 % by mass.
The method given in ISO 11890-1 is used when the VOC is greater than 15 % by mass. This document (method ISO 11890-2) applies when the system contains VOC and SVOC as the VOC result of ISO 11890-1 can be influenced by the SVOC. For VOC content smaller than 0,1 %, the head space method described in ISO 17895 is used as an alternative. ISO 11890-1 and ISO 17895 cannot be used for the determination of the SVOC content.
NOTE 1 Some ingredients of coating materials and their raw materials can decompose during analysis and cause artificial VOC and/or SVOC signals. When determining VOC and/or SVOC for coating materials and their raw materials, these signals are artefacts of the method and are not taken into account (examples are given in Annex B).
This method assumes that the volatile matter is either water or organic. However, other volatile inorganic compounds can be present and might need to be quantified by another suitable method and allowed for in the calculations. The method defined in this document is not applicable for determination of water content.
NOTE 2 If organic acids or bases and their corresponding salts are present in the coating material or its raw materials, the amount that is quantified by this method might not be accurate due to a change in the acid or base equilibrium.

This document describes procedures for measuring average grain size derived from a two-dimensional polished cross-section using electron backscatter diffraction (EBSD). This requires the measurement of orientation, misorientation and pattern quality factor as a function of position in the crystalline specimen[1]. The measurements in this document are made on two dimensional sections. The reader should note carefully the definitions used (3.3) which draw a distinction between the measured sectional grain sizes, and the mean grain size which can be derived from them that relates to the three dimensional grain size. NOTE 1 While conventional methods for grain size determination using optical microscopy are well-established, EBSD methods offer a number of advantages over these techniques, including increased spatial resolution and quantitative description of the orientation of the grains. NOTE 2 The method also lends itself to the measurement of the grain size of complex materials, for example those with a significant duplex content. NOTE 3 The reader is warned to interpret the results with care when attempting to investigate specimens with high levels of deformation.

This document specifies a method for the determination of selected perfluoroalkyl and polyfluoroalkyl substances (PFAS) in non-filtrated waters, for example drinking water, natural water (fresh water and sea water) and waste water containing less than 2 g/l solid particulate material (SPM) using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The compounds monitored by this method are typically the linear isomers. The group of compounds determined by this method are representative of a wide variety of PFAS. The analytes specified in Table 1 can be determined by this method. The list can be modified depending on the purpose for which the method is intended. The lower application range of this method can vary depending on the sensitivity of the equipment used and the matrix of the sample. For most compounds to which this document applies ≥0,2 ng/l as limit of quantification can be achieved. Actual levels can depend on the blank levels realized by individual laboratory. The applicability of the method to further substances, not listed in Table 1, or to further types of water is not excluded, but is intended to be validated separately for each individual case.

This part of ISO 17378 specifies a method for the determination of arsenic and antimony. The method
is applicable to drinking water, surface water, ground water, and rain water. The approximate linear
application range of this part of ISO 17378 for both elements is from 0,5 μg/l to 20 μg/l. Samples
containing higher concentrations than the application range can be analysed following appropriate
dilution.
Generally sea water is outside the scope of this part of ISO 17378. Sea water samples can be analysed
using a standard additions approach providing that this is validated for the samples under test. The
method is unlikely to detect organo-arsenic and organo-antimony compounds.
The sensitivity of this method is dependent on the selected operating conditions.

This document specifies a general method for determining the average molecular weight and the
molecular weight distribution of polymers using SEC-LS, i.e. size-exclusion chromatography coupled
with light-scattering detection. The average molecular weight and the molecular weight distribution
are calculated from molecular weight data and weight concentrations determined continuously with
elution time. The molecular weight at each elution time is determined absolutely by combining a
light-scattering detector with a concentration-sensitive detector. Therefore, SEC-LS is classified as an
absolute method.
This method is applicable to linear homopolymers and to nonlinear homopolymers such as branched,
star-shaped, comb-like, stereo-regular and stereo-irregular polymers. It can also be applied to
heterophasic copolymers whose molecular composition cannot vary. However, SEC-LS is not applicable
to block, graft or heterophasic copolymers whose molecular composition can vary. And the methods are
applicable to molecular weights ranging from that of the monomer to 3 000 000, but are not intended
for samples that contain > 30 % of components having a molecular weight < 1 000.

This Technical Specification gives a test method for determining the amounts of dimethyl fumarate (DMFu) in materials of textile products, desiccant sachets and other commodities.
The test method is not applicable to metal parts. The materials to which it is applicable are given in CEN/TR 16741:2015, Table 1.
NOTE In Europe, DMFu is prohibited in biocidal products as per Directive 98/8/EC. The substance must be used with caution to avoid any health problems in the chemistry laboratory. More recently, EU Commission Decision 2009/251/EC requires EU member states to ensure that products containing the biocide DMFu are not placed or made available on the market in the European Union. Decision 2009/251/EC establishes a maximum concentration of DMFu in products and parts of products of 0,1 mg/kg.

This document specifies a method for the determination of the individual glucosinolates content in
rapeseeds and rapeseed meals using high-performance liquid chromatography with gradient elution.
This method was tested on rapeseeds and rapeseed meals (Brassica rapa, Brassica napus and Brassica
juncea) but is applicable to other plant materials, on the condition that the occurring glucosinolates
previously identified are described in this document. On the contrary, the quantitative analysis of the
concerned glucosinolate(s) is not carried out.
NOTE This method does not determine glucosinolates that are substituted on the glucose molecule, but
these compounds are of little importance in commercial rapeseed and rapeseed meal.
Annex A presents the results of the interlaboratory trials for the gradient elution HPLC method.
Annex B presents how to check the titre of the prepared internal standard solution. Annex C presents
how to prepare and test the purified sulfatase solution and how to check the desulphation step on the
ion exchange column. Annex D presents the HPLC and column performance criteria qualification.
The analysis of glucosinolates content in rapeseed can also be done using an isocratic elution mode.
This requires some modifications of the method (internal, standard, HPLC column and HPLC buffers),
as described in Annex E.

This document specifies a reference method for the determination of milk fat purity using gas
chromatographic analysis of triglycerides. The method utilizes the differences in triglyceride
fingerprint of milk fat from the individual triglyceride fingerprints of other fats and oils to determine
samples which are outside the range normally observed for milk fat. This is achieved by using the
defined triglyceride formulae based on the normalized weighted sum of individual triglyceride peaks
which are sensitive to the integrity of the milk[6][7]. The integrity of the milk fat can be determined
by comparing the result of these formulae with those previously observed for a range of pure milk fat
samples[12]. Both vegetable fats and animal fats such as beef tallow and lard can be detected.
The method is applicable to bulk milk, or products made thereof, irrespective of the variation in
common feeding practices, breed or lactation conditions. In particular, the method is applicable to fat
extracted from milk products purporting to contain pure milk fat with unchanged composition, such as
butter, cream, milk and milk powder.
Because a false-positive result can occur, the method does not apply to milk fat related to these
circumstances:
a) obtained from bovine milk other than cow’s milk;
b) obtained from single cows;
c) obtained from cows whose diet contained a particularly high proportion of vegetable oils such as
rapeseed, cotton or palm oil, etc.;
d) obtained from cows suffering from serious underfeeding (strong energy deficit);
e) obtained from colostrum;
f) subjected to technological treatment such as removal of cholesterol or fractionation;
g) obtained from skim milk, buttermilk or whey;
h) obtained from cheeses showing increased lipolysis;
i) extracted using the Gerber, Weibull–Berntrop or Schmid–Bondzynski–Ratzlaff methods, or that
has been isolated using detergents (e.g. the Bureau of Dairy Industries method).
With the extraction methods specified in i), substantial quantities of partial glycerides or phospholipids
can pass into the fat phase.
NOTE 1 In nature, butyric (n-butanoic) acid (C4) occurs exclusively in milk fat and enables quantitative
estimations of low to moderate amounts of milk fat in vegetable and animal fats to be made. Due to the large
variation of C4, for which the approximate content ranges from 3,1 % fat mass fraction to 3,8 % fat mass fraction,
it is difficult to provide qualitative and quantitative information for foreign fat to pure milk fat ratios of up to
20 % mass fraction[11].
NOTE 2 In practice, quantitative results cannot be derived from the sterol content of vegetable fats, because
they depend on production and processing conditions. Furthermore, the qualitative determination of foreign fat
using sterols is ambiguous.
NOTE 3 Due to special feeding practices such as those related to c) and d), false-positive results have
sometimes been reported for milk from certain Asian regions[15]. Moreover, grass-only diets such as mountain
and, in particular, highland pasture feeding sometimes cause false-positive results, which can be substantiated
by a content of conjugated linoleic acid (C18:2 c9t11) of ≥ 1,3 % fatty acid mass fraction[16][17]. Nevertheless,
results conforming to the criteria of milk fat purity specified in this document are accepted, even if samples were
undoubtedly produced under conditions reported in this note, including those described in h).
NOTE 4 In cases where a positive result is suspected to be caused by circumstances related to c) or d), another
analytical method, such as fatty acid or sterol analysis, can be applied to confirm the finding. Due to similar or
increased limitations (e.g. as described in NOTE 1 and NOTE 2), a negative result obtained by another method is
not appropriate to contrastingly confirm milk fat purity.

This document specifies the sampling and analysis of phthalates in indoor air and describes the
sampling and analysis of phthalates in house dust and in solvent wipe samples of surfaces by means of
gas chromatography/mass spectrometry.
Two alternative sampling and processing methods, whose comparability has been proven in a round
robin test, are specified for indoor air[4]. Sampling can take place using sorbent tubes with subsequent
thermal desorption and GC-MS analysis. Alternatively, sampling can take on other types of sorbent
tubes that are subsequently analysed by solvent extraction with GC-MS.
Depending on the sampling method, the compounds dimethyl phthalate to diisoundecylphthalate
can be analysed in house dust as described in Annex C[8]. The investigation of house dust samples is
only appropriate as a screening method. This investigation only results in indicative values and is not
acceptable for a final assessment of a potential need for action.
Dimethyl phthalate to diisoundecylphthalate can be analysed in solvent wipe samples as described in
Annex B. Solvent wipe samples are suitable for non-quantitative source identification.
NOTE In principle, the method is also suitable for the analysis of other phthalates, adipates and cyclohexane
dicarboxylic acid esters, but this is confirmed by determination of the performance characteristics in each case.
General information on phthalates are given in Annex A.

This European Standard specifies a test method for the determination of the content of mono-aromatic, di-aromatic and tri+-aromatic hydrocarbons in diesel fuels that may contain fatty acid methyl esters (FAME) up to 30 % (V/V), in paraffinic diesel fuels that may contain fatty acid methyl esters (FAME) up to 7 % (V/V) and petroleum distillates in the boiling range from 150 °C to 400 °C. 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, may do so.
The precision statement of the procedure A, for regular distillates, has been established for diesel fuels with and without FAME blending components, with a mono-aromatic content in the range from 6 % (m/m) to 30 % (m/m), a di-aromatic content from 1 % (m/m) to 10 % (m/m), a tri+-aromatic content from 0 % (m/m) to 2 % (m/m), a polycyclic aromatic content from 1 % (m/m) to 12 % (m/m), and a total aromatic content from 7 % (m/m) to 42 % (m/m). The precision statement of the procedure B, for non-aromatic distillates, has been established for diesel fuels, with and without FAME blending components, with a mono-aromatic content in the range from 0,2 % (m/m) to 1,8 % (m/m), di-aromatic and polycyclic aromatic contents around 0,1 % (m/m), and a total aromatic content from 0,2 % (m/m) to 2 % (m/m).

This document specifies a method for the quantitative determination of the sum of short-chain
polychlorinated n-alkanes also known as short-chain polychlorinated paraffins (SCCPs) in the carbon
bond range n-C10 to n-C13 inclusive, in mixtures with chlorine mass fractions (“contents”) between
50 % and 67 %, including approximately 6 000 of approximately 8 000 congeners.
This method is applicable to the determination of the sum of SCCPs in unfiltered surface water, ground
water, drinking water and waste water using gas chromatography-mass spectrometry with electron
capture negative ionization (GC-ECNI-MS).
Depending on the capability of the GC-ECNI-MS instrument, the concentration range of the method
is from 0,1 μg/l or lower to 10 μg/l. Depending on the waste water matrix, the lowest detectable
concentration is estimated to be > 0,1 μg/l. The data of the interlaboratory trial concerning this method
are given in Annex I.

This document specifies a method for the determination of the dissolved fraction of selected active
pharmaceutical ingredients and transformation products, as well as other organic substances
(see Table 1) in drinking water, ground water, surface water and treated waste water.
The lower application range of this method can vary depending on the sensitivity of the equipment used
and the matrix of the sample. For most compounds to which this document applies, the range is ≥ 0,025 μg/l
for drinking water, ground water and surface water, and ≥ 0,050 μg/l for treated waste water.
The method can be used to determine further organic substances or in other types of water (e.g.
process water) provided that accuracy has been tested and verified for each case, and that storage
conditions of both samples and reference solutions have been validated. Table 1 shows the substances
for which a determination was tested in accordance with the method. Table E.1 provides examples of
the determination of other organic substances.

This draft European Standard specifies a method for quantitative determination of 17 2,3,7,8-chlorine substituted dibenzo-p-dioxins and dibenzofurans and dioxin-like polychlorinated biphenyls in sludge, treated biowaste and soil using liquid column chromatographic clean-up methods and GC/HRMS.
The analytes to be determined with this European Standard are listed in Table 1.
(...)
The limit of detection depends on the kind of sample, the congener, the equipment used and the quality of chemicals used for extraction and clean-up. Under the conditions specified in this European Standard, limits of detection better than 1 ng/kg (expressed as dry matter) can be achieved.
This method is "performance based". It is allowed to modify the method if all performance criteria given in this method are met.
NOTE   In principle this method can also be applied for sediments, mineral wastes and for vegetation. It is the responsibility of the user of this European Standard to validate the application for these matrices. For measurement in complex matrices like fly ashes adsorbed on vegetation it can be necessary to further improve the clean-up. This can also apply to sediments and mineral wastes.
