This document specifies different methods for quantitative determination of 16 polycyclic aromatic hydrocarbons (PAH) (see Table 2) in soil, sludge, treated biowaste, and waste, using GC-MS or HPLC-UV-DAD/FLD covering a wide range of PAH contamination levels (see Table 2).NOTE The method can be applied to sediments provided that validity is demonstrated by the user.When using fluorescence detection, acenaphthylene cannot be measured.[Table 2 -Target analytes of this document]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 document, the 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 can 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 document contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used.The method can be applied to the analysis of other PAH not specified in the scope, provided suitability is proven by proper in-house validation experiments.Sampling is not part of this standard. In dependence of the materials, the following standards need to be considered, e.g. EN 14899, ISO 5667-12 and EN ISO 5667-13.

This document specifies the derivation of biological equivalence (BEQ) concentrations for results of in vitro bioassays which are based on measuring effects on a biological process such as enzyme induction or cellular growth. The concept described here can be used for any biological assay after the proof of its applicability. To derive BEQ concentrations, the effect on a biological process caused by a sample – i.e. the activity of the sample – is expressed in terms of a concentration of a reference compound which results in an equivalent effect on the process. The term "sample" used in this document addresses environmental samples as well as defined mixtures and pure compounds used as test item in a bioassay. BEQ concentrations can be derived for environmental water samples, extracts of environmental water samples including tap water or solutions of pure chemicals or mixtures of chemicals.

This document specifies a method for the determination of the total metal content in leather using digestion of the leather and subsequent determination with inductively coupled plasma optical emission spectrometry (ICP-OES), inductively coupled plasma mass spectrometry (ICP-MS), atomic absorption spectrometry (AAS) or spectrometry of atomic fluorescence (SFA). This method determines the total metal content in leather; it is not compound-specific or specific to the oxidation state of the metals. The method is applicable for determining the following metals: This method is also suitable for determining Boron (B) in leather. In the case of chromium-tanned leathers, it is often more relevant to use ISO 5398-1[1], ISO 5398-2[2], ISO 5398-3[3] or ISO 5398-4 [4]. Interlaboratory test results and the quantification limits possible with ICP-OES are given in Table A.1 and Table A.2 of Annex A. For the determination of Al and Ti in leather the extraction procedure given in Annex B shall be used.

This document is a method for determining ethoxylated alkylphenols (nonyphenol ethoxylate [NPEOn with 1 = n = 16] and octylphenol ethoxylate [OPEOn with 1 = n = 16]) in leather. This direct method is especially suitable where a larger number of leather samples are to be checked for the presence of ethoxylated alkylphenols. This method requires the use of high-performance liquid chromatography (HPLC) with triple quadrupole mass spectrometer (MSMS) to identify and quantify the ethoxylated alkylphenols.

This document specifies a method for the determination of the dissolved anions chlorate, chloride, and chlorite in water with low contamination (e.g. drinking water, raw water or swimming pool water). The diversity of the appropriate and suitable assemblies and the procedural steps depending on them permit a general description only. For further information on the analytical technique see Reference [7]. An appropriate pre-treatment of the sample (e.g. dilution) and the use of a conductivity detector (CD), UV detector (UV) or amperometric detector (AD) make the working ranges given in Table 1 feasible.

This document provides guidance for: The activity concentration is expressed in becquerel per cubic metre (Bq·m-3). This document does not cover the details of measurement test techniques (gamma spectroscopy, global alpha and beta counting, liquid scintillation, alpha spectrometry) used to determine the activity deposited in the media filter, which are either based on existing standards or internal methods developed by the laboratory in charge of those measurements. Also, this document does not cover the variability of the aerosol sizes as given by the composition of the dust contained in ambient air [3],[4]. The procedures described here facilitate the sampling of aerosol bound radionuclides. It is supposed to conform to the national and international requirements for monitoring programmes safety standards of IAEA [5]. The characteristics of the sampling location (coordinates, type of vegetation, obstacles) need to be documented prior to commencing the monitoring. The guidelines of WMO include the criteria for representative measurements of temperature, wind-speed, wind direction, humidity and precipitation for all the weather stations in the world [6].

This part of ISO 21940 sets out the requirements for evaluating hard and soft bearing balancing machines that support and rotate:

This document establishes general requirements for organizations, that offer guided or self-guided visits in order to enable visitors, to learn: The requirements of this document are applicable to those visits and their related services, including their facilities and equipment, as well as their internal operation, in order to enhance the tourism experience of the visitor. This document does not apply to natural protected areas for which ISO 18065:2015 applies, or to recognized museums.

This technical document specifies requirements for immersion suits for use by helicopter crew members and passengers in the event of a ditching or water impact, to ensure minimum levels of performance. It applies to immersion suits for use by adults only.

This document provides requirements and recommendations governing data category specifications for language resources. It specifies mechanisms for creating, documenting, harmonizing and maintaining data category specifications in a data category repository. It also describes the structure and content of data category specifications. The intended audience of this document is researchers and practitioners in fields of language resource management who use data categories and data category specifications.
