This document specifies requirements for so-called "cold bubble-through" or "cold pass-over" humidifying equipment, hereafter referred to as a passive humidifier. Figure 1 and Figure 2 illustrate these passive humidifiers.
NOTE 1 Passive humidifier humidification chambers are at room temperature so they have a lower
humidification output than active humidifiers.Cross References:IEC 60601-1-11:2015ISO 14971:2007ISO 5367:2014ISO 16142-1:2016ISO 80369-1:2010EN 13544-2:2002+A1:2009ISO 17664:2017ISO 80601-2-12:2011/Cor 1:2011ISO 23328-2:2002ISO 5356-1:2015IEC 61672-1:2013ISO 13485:2016ISO 7396-1:2016IEC 62366-1:2015/COR1:2016ISO 80601-2-74:2017ISO 10993-1:2009/Cor 1:2010ISO 15223-1:2016ISO 4135:2001ISO 3744:2010ISO 14937:2009ISO 18562-1:2017EN 13544-2:2002+AMD1:2009IEC 60601ISO 9360-2:2001ISO 10524-1:2006ISO 10780:1994ISO 594-2:1998ISO 594-1:1986IEC 60601-2-19:2009/COR1:2012ISO 80369-7:2016ISO 9360-1:2000EN 15986:2011IEC/TR 60878-1:2015ISO 14159ISO 27427ISO 80369-2ISO 8185ISO 80601-2-70ISO 80601-2-69Incorporates the following:Corrigendum, October 2019
