ISO/CD 9360-3

Anaesthetic and respiratory equipment – Heat and moisture exchangers and breathing system filters (HMEF) for humidifying respired gases in humans — Part 3: Measurement of filtration performance

Apstrakt

ISO 23328-2:2002 specifies requirements for non-filtration aspects of breathing system filters (BSF) intended for anaesthetic and respiratory use, and addresses connection ports, leakage, resistance to flow, packaging, marking and information supplied. The test method is intended for BSF used with a clinical breathing system.
It is not applicable to other types of filter, e.g. those designed to protect vacuum sources or gas sample lines, to filter compressed gases, or to protect test equipment for physiological respiratory measurements.
A method for assessing filtration performance of BSF is given in ISO 23328-1.
