Sl.No. Synosis Points
1 Scope: This standard specifies culture methods for the isolation of Legionella and estimation of their numbers in water samples. These methods are applicable to all kinds of water samples including potable, industrial, waste and natural waters. These methods can be used for water related matrices, e.g. biofilms, sediments, etc. Not all Legionella species are culturable; therefore, the methods described in this document do not recover all species of Legionella.
2 The standard also specifies normative references, terms and definitions, principle, apparatus and glassware, culture media and reagents, sampling, procedure, expression of results, test results and quality assurance.
