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.

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.

This part of the EN 20 series specifies a method for the determination of the protective effectiveness or
the toxic values of a wood preservative against infection by Lyctus brunneus (Stephens) in wood which
has been treated previously by full impregantion.
This method is applicable to:
— water-insoluble chemicals which are being studied as active insecticides; or
— organic formulsation, as supplied or as prepared in the laboratory by dilution of concentrates.
This method is applicable to water-based preservatives.
NOTE This method can be used in conjuction with ageing procedures, which do not remove the added nutrient.

This document specifies a method for the determination of the curative action of a wood preservative
against infestation by Anobium punctatum (De Geer) when the product is applied as a surface treatment
to wood.
This method is applicable to any surface-applied treatment that is intended to prevent emergence of adult
beetles but not intended to kill larvae in infested timber.
NOTE 1 This method can be used in conjunction with an ageing procedure, for example EN 73.
NOTE 2 Products intended to kill larvae can be tested by the method described in EN 48.

This document defines the structure of a standardized digital representation of an asset, called Asset Administration Shell. The Asset Administration Shell gives uniform access to information and services. The purpose of the Asset Administration Shell is to enable two or more software applications to exchange information and to mutually use the information that has been exchanged in a trusted and secure way. This document focusses on Asset Administration Shells representing assets of manufacturing enterprises including products produced by those enterprises and the full hierarchy of industrial equipment. It defines the related structures, information, and services. The Asset Administration Shell applies to: - any type of industrial process (discrete manufacturing, continuous process, batch process, hybrid production); - any industrial sector applying industrial-process measurement, control and automation; - the entire life cycle of assets from idea to end of life treatment; - assets which are physical, digital, or intangible entities.
