Water quality - Detection and enumeration of Legionella - Part 2 : direct membrane filtration method for waters with low bacterial counts.
This part of ISO 11731 describes a monitoring method for the isolation and enumeration of Legionella organisms in water intended for human use (e.g. hot and cold water, water used for washing), for human consumption and for treated bathing waters (e.g. swimming pools). It is especially suitable for waters expected to contain Iow numbers of Legionella. As the growth of Legionella may be inhibited by bacterial colonies on the membrane, the method is only suitable for waters containing Iow overgrowth of other bacterial colonies on the membrane, the method is only suitable for waters containing low bacterial counts.

Water quality - Detection and enumeration of Legionella - Part 2: Direct membrane filtration method for waters with low bacterial counts (ISO 11731-2:2004)
This International Standard describes a monitoring method for the isolation and enumeration of Legionella organisms in water intended for human use (e.g. not and cold water, water used for washing), for human consumption and for treated bathing waters (e.g. swimming pools). It is escpecially suitable for waters expected to contain low number of Legionella. As the growth of Legionella may be inhibited by overgrowth of other bacterial colonies on the membrane, the method is only suitable for waters containing low bacterial counts.
Water quality - Detection and enumeration of Legionella - Part 2: Direct membrane filtration method for waters with low bacterial counts
This International Standard specifies a method for the isolation and enumeration of Pseudomonas aeruginosa in samples of bottled water by a membrane filtration technique. This method can also be applied to other types of water with a low background flora, for example, pool waters and waters intended for human consumption.

Water quality - Detection and enumeration of Legionella - Part 2: Direct membrane filtration method for waters with low bacterial counts
Gives a procedure for the evaluation and comparison of water-testing filters intended for the enumeration of specific organisms and mixed microbial populations. The procedure provides general guidelines for comparative testing of the recoveries of bacteria, yeasts and other fungi on membrane filters, as compared to recoveries by the spread plate and pour plate techniques.

Water quality - Detection and enumeration of Pseudomonas aeruginosa - Method by membrane filtration (ISO 16266:2006)
This document presents guidance for carrying out manipulations which are common to each technique for the microbiological examination of water, particularly the preparation of samples, culture media and apparatus. It also describes the various enumeration techniques available and the criteria for the choice of a particular technique. This document is mainly intended for bacteria. yeasts and moulds. Some aspects are also applicable to viruses and parasites.

Water quality-Guidance on validation of microbiological methods
This part of ISO 9308 describes a reference method (Standard Test) for the detection and enumeration of Escherichia coli and coliform bacteria in water for human consumption. The Standard Test has a low selectivity, allowing the detection of injured bacteria. Due to the low selectivity, background growth can interfere with the reliable enumeration of coliform bacteria and E. coli, for example in some drinking waters, like shallow well waters or surface waters. This method is not suitable for these types of water. The Standard Test is based on membrane filtration, subsequent culture on a differential agar medium and calculation of the number of target organisms in the sample.
