This document outlines requirements for sampling from hydrogen fuelling stations for samples taken at the dispenser. The document defines the best practice for sampling at the nozzle of a hydrogen fuelling station as part of the fuelling station acceptance testing, and ongoing operation. Further, the document describes the minimum safety requirements for sampling. This document is targeted for the sampling from the hydrogen fuelling station dispenser. Many of the generic requirements within this document are applicable to sampling at other locations within the hydrogen fuelling station, which can be carried out for hydrogen quality assurance, see ISO 19880-8, however, further specific requirements that can be necessary for safe sampling are not addressed in this document. The intention of sampling hydrogen is to enable analysis against the requirements of ISO 14687, and by analytical methods validated by protocols described in ISO 21087. This document supersedes, and is an extension to, the guidance published in ISO 19880-1:2020, Annex K. NOTE Analytical methods are divided into on-line analyses and off-line analyses. On-line analysis allows for real time analysis at hydrogen stations and is not covered in this document.

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.

present approach is particularly suited to handle the wide diversity of matrices in cosmetics. This
document only applies to already fully-developed and finalized methods for which selectivity/
specificity have already been studied and the scope of the method to be validated has already been
defined, in terms of matrix types and measurand (for example analyte) concentrations.

This document specifies a method for the determination of the toxic values of a wood preservative against
the Reticulitermes species of European termites.
NOTE 1 The method can be applied not only to different species of Reticulitermes, but also to other species of
the family of the Rhinotermitidae, adapting the conditions of temperature and humidity where necessary to the
specific requirements of the species concerned.
This method is applicable to:
— water-insoluble chemicals which are being studied as active insecticides;
— organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of
concentrates;
— water-soluble materials, for example salts.
NOTE 2 This method can be used in conjunction with an ageing procedure, for example EN 73 or EN 84.

This document defines the minimum requirements for treatment systems, which generate the active substance - "Active chlorine" - from sodium chloride by electrolysis for on-site (in-situ) operation.
The in-situ generated active substance (IGAS), in this case active chlorine, may be put into a solution ("off-line") or directly generated in the pipes ("in-line").
This document specifies the device construction, and test methods for the equipment used for in-situ generation of active chlorine. It specifies requirements for instructions for installation, operation, maintenance, safety and for documentation to be provided with the product.
The in-situ generation of active substances and the placing of their precursors on the EU market are subject to the specifications of the Biocidal Products Regulation (EU) 528/2012 ["Biocidal products"]). Active substances, generated by devices, which are claiming compliance with this document, shall comply with the BPR for both the registered active chlorine, quality standards and the precursor in accordance with appropriate application and "Product Type" as listed in the BPR.
This standard does not identify applications for in situ devices for generation of active chlorine. The range of applications for in-situ generation of chlorine is diverse. It is the responsibility of the economic operator/product supplier, claiming compliance with this standard, to identify the appropriate system type and operating conditions for the specific application and to:
-   specify the quality of the biocide appropriate to the application. This may be defined in national or international standards;
-   specify the appropriate product type (see Clause 7) and operating conditions (concentration, dosage rate and quality of the active chlorine);
-   specify any other regulatory requirements relevant to the specific application;
-   specify the appropriate precursor sodium chloride (natural or artificial brine), for the application;
-   and to label the product accordingly.

This document describes the static gravimetric preparation of Class II calibration gas mixtures and describes a method for calculating the measurement uncertainty associated with the amount fraction of each component. In addition to all of the contributions to the measurement uncertainty mentioned in ISO 6142-1, this document also considers the uncertainty resulting from the validation process for Class II mixtures that are not individually verified, as is the case for Class I mixtures. This document extends the uncertainty evaluation described in ISO 6142-1 to include the effects of batch production and the verification process. It provides guidance on how to derive an uncertainty budget that is representative of a particular category of mixtures. Methods for the batch production of more than one mixture in a single process are included in this document. This document is only applicable to mixtures of gaseous or totally vaporized components, which can be introduced into the cylinder in the gaseous or liquid state. Both binary and multi-component gas mixtures are covered by this document. This document is limited to non-reactive molecules/components that are greater than or equal to an amount fraction of 100 μmol/mol. This document excludes components that react with each other, or with common mixture contaminants such as water vapour or oxygen or react with the inner surface of the cylinder and valve in the form of absorption or adsorption.
