In EN 60601-1:1990 this type of European Standard is referred to as a “Particular Standard“. As stated in
41、1.3 of EN 60601-1:1990, the requirements of this European Standard take precedence over those of EN 60601-1:1990. Clauses and subclauses additional to those in EN 60601-1:1990 are numbered beginning 101. Additional annexes are lettered beginning AA. Additional items in lettered lists are lettered be
42、ginning aa). Additional tables and figures are numbered beginning 101. Annex AA contains rationale statements for this Part of this European Standard. The clauses and subclauses which have corresponding rationale statements are marked with R) after their number. DIN EN 794-3:2009-12 EN 794-3:1998+A2
43、:2009 (E) 6 Section one. General 1 Scope The scope given in clause 1 of EN 60601-1:1990 applies with the following addition: 1.101 R) This part of this European Standard specifies requirements for ventilators, driven by a power source and intended for emergency and transport use. This covers a range
44、 of devices, from relatively simple ventilators intended, primarily, for use with a face mask and for limited periods (e.g. gas powered ventilators) through to devices for pre-planned longer term use. !This includes gas-powered resuscitators, which are generally used by first responders.“ This part
45、does not cover operator-powered ventilators (i.e. manual resuscitators). Ventilators aboard aircraft are likely to be subject to additional requirements and national/international regulations. Additional parts, e.g. concerning lung ventilators for critical care (see EN 794-1), home care ventilators
46、(see EN 794-2), operator powered resuscitators and recent developments such as jet and very high frequency ventilation and oscillation are published or under consideration. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications.
47、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 incorporated in it by amendment or revision. For un
