This document specifies a method for the determination of the boiling range distribution of petroleum products. The method is applicable to petroleum products and fractions with a final boiling point of 538 °C or lower at atmospheric pressure as determined by this document. This document does not apply to gasoline samples or gasoline components. The method is limited to products having a boiling range greater than 55 °C and having a vapour pressure sufficiently low to permit sampling at ambient temperature. The document describes two procedures. a) Procedure A allows a larger selection of columns and analysis conditions, such as packed and capillary columns as well as a thermal conductivity detector in addition to the flame ionization detector. Analysis times range from 14 min to 60 min. b) Procedure B is restricted to only three capillary columns and requires no sample dilution. The analysis time is reduced to about 8 min. Both procedures have been successfully applied to samples containing fatty acid methyl esters (FAME) up to 20 % (volume fraction). NOTE For the purposes of this document, the terms "% (mass fraction)" and "% (volume fraction)" are used to represent the mass fraction (µ), the volume fraction (φ) of a material.

This document specifies the method for the characterisation of the compaction response of fibrous reinforcements used in liquid composite moulding. Specimens are compressed at a controlled speed to a predetermined thickness and the relative compressive load is measured. In this method, specimens are tested in both the saturated (“wet”) and unsaturated (“dry”) state. The following steps explain how to prepare the test setup and characterise the compaction response. This method specifies the speed of testing. It should be noted that testing at different speeds can yield different results which may not be comparable.

This document does not apply to the following: — Underground water tanks; — Mobile water tanks.

This European Standard specifies the requirements and tests for the construction, performance, safety and conformity of conversion devices used to determine the energy of fuel gases described in the Table 1, including those of the 1st and 2nd families according to EN 437. The energy conversion device (ECD) considered in this standard consists of an energy calculator (EC) and is associated with the following devices and/or functions: - a volume conversion device (VCD) or a flow computer used as gas meter conversion, either conforming to EN 12405-1, or to prEN 12405-3, for high accuracy measurements; - a calorific value determination device (CVDD). Requirements for type approval tests of the devices, not included in the above-mentioned standards are described in appropriate annexes specified in Table 6. For the purpose of this European Standard, the term "volume conversion devices" (VCDs) includes flow computers (FCs). A single calculator may undertake the volume conversion functions for different metering lines.

This document specifies methods for determining the pot life of multi-part adhesives, in order to be able to determine whether the pot life conforms to the minimum specified working life required of an adhesive. The different methods described in this document to measure the property do not necessarily provide identical results. The test methods described are suitable for assessing all multi–part adhesives, and especially epoxy based and polyurethane based adhesives, but they are not suitable for some acrylic-based adhesives. NOTE 1      Some of the methods described in this document can also be suitable for determination of working life of one-part adhesives that react to humidity (e.g. PUR prepolymers). NOTE 2      This document can also be used for assessing non-structural adhesives.

This document specifies accessibility requirements and recommendations for accessible charging stations for electric road vehicles, following a “Design for All”/“Universal Design” approach. This document applies to the charging infrastructure for M1 electric vehicles, which are used for the carriage of passengers and are equipped with at least four wheels and comprising not more than eight seats in addition to the driver's seat, and for N1 electric vehicles, which are used for the carriage of goods and having a maximum mass not exceeding 3,5 tonnes. This document sets out requirements and recommendations designed to ensure that the charging infrastructure is accessible and usable for all drivers, including those with specific mobility needs. Autonomous driving vehicles are excluded from the scope of this document. This document is applicable to charging infrastructures, whether public or private, intended for electric vehicle charging. While it primarily addresses requirements and recommendations for conductive charging, wireless/inductive charging is also considered where relevant. This document covers: — the built environment surrounding electric vehicle charging stations, including its location, identification, signage and information; — the built environment close to the electric vehicle to enable the charging process; — factors to be taken into account in the design and specification of electric vehicle supply equipment; — the platform and applications to enable the type of charging and payment, when relevant; — other possible basic services associated with the charging process: pedestrian connection, associated toilets, etc. This document does not cover: — electric vehicles categories other than M1 and N1, although its users could also benefit from the requirements given in this document; — specific materials used within an electric vehicle supply equipment; — definition of charging rates or charging prices; — user personal safety and protection; — grid connections for electric vehicle charging stations; — parking policy and planning policy related to designated accessible parking spaces or electric vehicle charging. NOTE Some of the requirements given in this document might not be applicable to private infrastructures (e.g. the ones related to the payment system).

This document specifies a method for the determination of the chloride content in ammonium nitrate fertilizers of high nitrogen content. This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants, and where the following category: inorganic fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.
