La présente Norme européenne décrit les règles les plus pertinentes des Codes de nomenclature botanique et zoologique, dont l'application est nécessaire pour obtenir un relevé non équivoque de la biodiversité dans l'environnement aquatique. Elle indique en outre comment gérer les changements taxonomiques par rapport aux noms taxonomiques enregistrés.

This European Standard describes the most relevant rules of the Botanical and Zoological Codes necessary for unequivocal recording of biodiversity in the aquatic environment. Furthermore, guidance is given on how to deal with taxonomic changes in relation to recorded taxonomic names. NOTE A Code only affects taxonomic changes carried out in the period covered by that particular edition of the Code.

La présente Norme internationale spécifie une procédure d'évaluation qui permet de comparer deux méthodes avec des caractéristiques de performance établies conformément à l'ISO/TR 13843 et visant à quantifier le même groupe cible ou la même espèce de micro-organismes.Elle fournit les bases mathématiques pour évaluer les performances relatives moyennes des deux méthodes quantitatives par rapport à des critères de comparaison déterminés. Elle ne fournit aucune donnée permettant d'évaluer la fidélité des méthodes comparées. Il convient que la fidélité des méthodes soit évaluée lors de la détermination de leurs caractéristiques de performance.La présente Norme

This International Standard specifies an evaluation procedure for comparing two methods with established performance characteristics according to ISO/TR 13843 and intended for the quantification of the same target group or species of microorganisms. This International Standard provides the mathematical basis for the evaluation of the average relative performance of two quantitative methods against chosen criteria for the comparison. It does not provide data for assessment of the precision of the methods being compared. It is appropriate that the precision of methods is assessed as part of their performance characterization. This International Standard does not provide methods for the verification of method performance characterization in a single laboratory.

This British Standard gives recommendations and guidance on the assessment of the risk of legionellosis presented by artificial water systems. It is applicable to any undertaking involving a work activity or premises controlled in connection with a trade, business or other undertaking where water is used or stored in circumstances that could cause a reasonably foreseeable risk of exposure to legionellae and contracting legionellosis. The standard is applicable to risk assessments being undertaken on premises, plant and systems for the first time, and to review and audit where a previous assessment has been undertaken and where control measures might have been implemented. This British Standard does not give recommendations for: a) the assessment of the risk presented by natural waters, including rivers, lakes, ponds, waterfalls, caves, dew ponds or natural recreational facilities, such as boating lakes; or b) the preparation of the scheme of control for the risk systems identified.

ISO 17994:2004 defines an evaluation procedure for comparing two methods intended for the detection or quantification of the same target group or species of microorganisms. ISO 17994:2004 provides the mathematical basis for the evaluation of the average relative performance of two methods against chosen criteria of equivalence. Any two enumeration methods based on counts (of colonies or positive tubes) or any two detection methods (presence/absence methods) intended for the same purpose can be compared. ISO 17994:2004 provides no solution to directly compare a quantitative method (colony count or MPN) with a detection method (P/A).
