| 1 | Scope: This document specifies a method for the detection and quantification of Legionella spp. and L. pneumophila using a quantitative polymerase chain reaction (qPCR). It specifies general methodological requirements, performance evaluation requirements, and quality control requirements. | |
| 2 | Technical details specified in this document are given for information only. Any other technical solutions complying with the performance requirements are suitable. | |
| 3 | This document is intended to be applied in the bacteriological investigation of all types of water (hot or cold water, cooling tower water, etc.), unless the nature and/or content of suspended matter and/or accompanying flora interfere with the determination. This interference can result in an adverse effect on both the detection limit and the quantification limit. | |
| 4 | The results are expressed as the number of genome units of Legionella spp. and/or L. pneumophila per litre of sample. | |
| 5 | The method described in this document is applicable to all types of water. However, some additives, such as chemicals used for water treatment, can interfere with and/or affect the sensitivity of the method. | |
| 6 | The standard also includes normative references, terms, definitions, symbols and abbreviated terms, principle, sampling, general testing conditions, procedure, expression of result, technical protocol for the characterization and the validation of the method, quality controls and test report. | |
