适用范围

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.
