This document specifies the performance test of data acquisition and handling systems (DAHS). This includes specification of- test procedures;- description of laboratory test;- requirements on the test laboratory.This document supports the requirements of EN 14181 and legislation such as the IED, MCPD and E-PRTR. It does not preclude the use of additional features and functions provided the minimum requirements of this document are met and that these features do not adversely affect data quality, clarity or access.

This document determines the fuel quality classes and specifications of graded hog fuel and wood chips for industrial use. It covers only hog fuel and wood chips produced from the following raw materials (see ISO 17225-1:—, Table 1):— 1.1 forest, plantation and other virgin wood;— 1.2 by-products and residues from wood processing industry;— 1.3.1 chemically untreated used wood;— 1.4 blends and mixtures.This document covers hog fuel, which is produced with blunt tools, and wood chips, which are produced with sharp tools.NOTE 1 1.2.2 By-products and residues from wood processing industry, which can include chemically treated material (e.g. glued, painted, laminated) are not allowed include halogenated organic compounds or heavy metals at levels higher than those in typical virgin material values (see Annex B in ISO 17225-1) or higher than typical values of the country of origin.NOTE 2 If class I4 includes chemically treated used wood (1.3.2), it can be only used in the installations permitted to use 1.3.2.

This document specifies minimum requirements for the materials, design, construction, prototype testing and routine manufacturing inspections of fully wrapped composite gas cylinders for compressed, liquefied and dissolved gases.NOTE 1 For the purposes of this document, the word "cylinder" includes tubes (seamless transportable pressure receptacles of a water capacity exceeding 150 litres and of not more than 3 000 litres).This document is applicable to cylinders that comprise a liner of metallic material (welded or seamless) or non-metallic material (or a mixture thereof), reinforced by a wound composite consisting of fibres of glass, carbon or aramid (or a mixture thereof) embedded in a matrix.This document is also applicable to composite cylinders without liners.This document is not applicable to gas cylinders which are partially covered with fibres and commonly called "hoop wrapped" cylinders. For hoop wrapped composite cylinders, see EN 12257.NOTE 2 This document does not address the design, fitting and performance of removable protective sleeves. Where these are fitted, they are considered separately.This document is primarily for compressed, liquefied and dissolved gases other than LPG.NOTE 3 For dedicated LPG cylinders, see EN 14427.

This analytical procedure specifies a reverse phase high performance liquid chromatographic with UV detection (RP-HPLC-UV) method for the simultaneous determination of four authorized carotenoids in fish compound feed, namely astaxanthin (AXN), canthaxanthin (CXN), adonirubin (ADR) and astaxanthin dimethyldisuccinate (AXN DMDS), and of six authorized carotenoids in poultry feed, namely canthaxanthin (CXN); capsanthin (CSN), ethyl ester of beta-apo-8'-carotenoic acid (BACARE), citranaxanthin (CIXN), lutein (LUT) and zeaxanthin (ZEA) at levels ranging from ca. 2 to ca. 4 500 mg/kg (depending on the carotenoid). Beta-carotene (BCAR), authorized in compound feed for all animal species, was also added to the scope. The analytical procedure is fit for the purpose of quantitation of declared carotenoids and labelling confirmation. The procedure applies to natural and synthetic feed additives.Xanthophyll esters like those of lutein, zeaxanthin and capsanthin that might be present in feed materials are not authorized feed additives and therefore not part of the scope of this method.

This international standard specifies minimum requirements for generating and analyzing whole-genome sequence (WGS) data obtained from foodborne bacteria. These requirements are applicable to any sequencing platform or chemistry. This process may include the following stages:• Handling of bacterial cultures;• Genomic DNA isolation;• Sequencing library preparation, sequencing, and assessment of raw DNA sequence read quality and storage;• Bioinformatic analysis, including methods such as high quality single nucleotide polymorphism (hqSNP)analysis, core genome and whole genome multi-locus genotyping (cgMLST, wgMLST), and bioinformatic pipeline validation; and• Metadata capture and sequence repository deposition.

This document specifies a method for determining the chemical resistance properties of glass-reinforced thermosetting plastics (GRP) pipes and fittings in a deflected condition for nominal sizes DN 100 and larger. In conjunction with ISO 10928, this document provides a method for evaluating the effect of a chemical environment on the interior of a pipe or fitting after a specified period of time. Test conditions and requirements are specified in the referring International Standard. ISO 23856 references this document.

This document specifies terms and definitions that are related to the assessment of workplace exposure to chemical and biological agents. These are either general terms or are specific to physical and chemical processes of air sampling, the analytical method or method performance.The terms included are those that have been identified as being fundamental because their definition is necessary to avoid ambiguity and ensure consistency of use.

This document specifies fume cupboards for work with unsealed radioactive materials with specific requirements regarding radiation protection and it does not apply to glove boxes or hot cells not even to a emitting radioisotopes.The purpose of this document is to set out rules for the design and testing of fume cupboards for work with unsealed radioactive materials, in order to provide guidelines for the planner, installer, operator, assessor and the authorities.NOTE If, when handling unsealed radioactive substances, radiopharmaceuticals are produced for use on humans, the fume cupboards covered by this document are not sufficient.Before using radioactive materials, a safety assessment needs to be performed. To find the maximum activity allowed for every activity with radioactive material it is necessary to take into account the three principles of radiological protection, namely justification, optimization, and the application of dose limits, clarifying how they apply to radiation sources delivering exposure and to individuals receiving exposure. Shield and abatement system required are also evaluated.
