BS EN 13544-2:2002+A1:2009EN 13544-2:2002+A1:2009 (E) 4 1 Scope This part of EN 13544 specifies requirements for tubing to be used with equipment for the therapeutic administration of respirable g
22、ases in domiciliary, ambulance and hospital practice including the interface to the equipment i.e. nipples and screw threaded connectors. This tubing is mainly used with oxygen, air or mixtures of these gases. The interface specifications are given to ensure interchangeability of respiratory therapy
23、 equipment thereby enabling patients to receive continuous treatment in all these clinical situations. Weight-bearing screw-threaded connectors are specified for use at the outlet of e.g. flowmeters to which devices such as humidifiers or nebulizers can be attached. NOTE This standard does not speci
24、fy the devices where these connectors have to be used. It is expected that specific device standards will specify the devices where these connectors are going to the used e.g. EN ISO 10651-4, EN 738-1 and EN 13220. 2 Normative references This European Standard incorporates by dated or undated refere
25、nce, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporat
26、ed in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).
