ISO/TC 146/SC 6/WG 10 - Microbial contaminants

This document specifies a method to evaluate the capacity of air purifiers to reduce the concentration of airborne culturable bacteria. The test is applicable to air purifiers commonly used in single room spaces.

ISO 16000-20:2014 specifies requirements for sampling of moulds from air. Following the instructions given, samples are obtained for microscopy to determine the total concentration of spores.

ISO 16000-21:2014 specifies requirements for sampling of moulds from building materials. Following the instructions given, samples are obtained for microscopy or for subsequent detection of moulds by cultivation according to ISO 16000-17.

ISO 16000-19:2012 describes the measurement strategy for the detection of fungi in indoor environments. ISO 16000-19:2012 describes suitable sampling and analysis methods together with a description of the applicability and the interpretation of the measurement results to maximize the comparability of the measured data obtained for a given measurement objective. It does not include details on recording building characteristics or field inspections by qualified professionals which have to take place prior to any microbiological measurement. ISO 16000-19:2012 is not applicable to a detailed description of the building physics- and building-engineering-related procedures applicable to field inspections. The methods and procedures presented do not allow quantitative exposure assessment with regard to the room occupants. The application of ISO 16000-19:2012 presupposes the knowledge of ISO 16000-1.

This part of ISO 16000 specifies requirements for short-term (1 min to 10 min) sampling of moulds in indoor air by impaction on solid agar media. Following the instructions given, a sample is obtained for subsequent detection of moulds by cultivation in accordance with ISO 16000-17.

ISO 16000-18:2011 specifies requirements for short-term (1 min to 10 min) sampling of moulds in indoor air by impaction on solid agar media. Following the instructions given, a sample is obtained for subsequent detection of moulds by cultivation in accordance with ISO 16000-17.

This part of ISO 16000 specifies a method for the detection and enumeration of moulds by cultivation after sampling by impaction according to ISO 16000-18 or by filtration according to ISO 16000-16. It is also suitable for cultivation of moulds from material suspensions or from direct plating.

ISO 16000-16:2008 specifies requirements for long-term (0,5 h to several hours) sampling of moulds in indoor air by filtration. Following the instructions given, a sample is obtained for subsequent detection of moulds by cultivation after suspension according to ISO 16000-17, which is part of the complete measurement procedure. ISO 16000-16:2008 is not suitable for personal sampling.

ISO 16000-17:2008 specifies a method for the detection and enumeration of moulds by cultivation after sampling by impaction according to ISO 16000-18:— or by filtration according to ISO 16000-16. It is also suitable for cultivation of moulds from material suspensions or from direct plating.
