25、word Canadian Standards Association provides certification services for manufacturers who, under license from CSA, wish to use the appropriate registered CSA Mark on certain products f their manufacture to indicate conformity with CSA Standards. CSA Certification for a number of products is provided
26、 in the interest of maintaining agreed-upon standards of quality, performance, interchangeability and/or safety, as appropriate. Where applicable, certification may form the basis for acceptance by inspection authorities responsible for enforcement of regulations. Where feasible, programs will be de
27、veloped for additional products for which certification is desired by producers, consumers or other interests. In performing its functions in accordance with its objectives, CSA does not assume or undertake to discharge any responsibility of the manufacturer or any other party. The opinions and find
28、ings of the Association represent its professional judgement given with due consideration to the necessary limitations of practical operation and state of the art at the time the Standard is processed. Products in substantial accord with this Standard but which exhibit a minor difference or a new fe
29、ature may be deemed to meet the Standard providing the feature or difference is found acceptable utilizing appropriate CSA Certification Division Operating Procedures. Products which comply with this Standard shall not be certified if they are found to Rave additional features which are inconsistent
30、 with the intent of this Standard. Products shall not be certifiable if they are discovered to contravene applicable Federal laws or regulations. Testing techniques, test procedures and instrumentation frequently must be prescribed by the CSA Certification Division in addition to the technical requi
31、rements contained in Standards of CSA. In addition to markings specified in the Standard the CSA Certification and Testing Division may require special cautions, markings and instructions that are not specified by the Standard. Some tests required by CSA Standards may be inherently hazardous. The As
32、sociation neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed, whether performed in whole or in part by the manufacturer or the Association, and whether or not any equipment, facility or personnel for or in conne
33、ction with the test is furnished by the manufacturer or the Association. Manufacturers should note that, in the event of the failure of the CSA Certification and Testing Division to resolve an issue arising from the interpretation of requirements, there is an appeal procedure: the complainant should
34、 submit the matter, in writing, to the Secretary of the Canadian Standards Association. If this Standard is to be used in obtaining CSA Certification please remember, when making application for certification, to request all current Amendments, Bulletins, Notices and Technical Information Letters th
35、at may be applicable and for which there may be a nominal charge. For such information or for further information concerning details about CSA Certification please address your inquiry to the Applications and Records Section, Canadian Standards Association, 1 78 Rexdale Boulevard, Etobicoke, Ontario
36、 M9W 1 R3. March 7997 Blank pageAnaesthetic Muchines for Medical Use 21 68.3-97 Anaesthetic Machines for Medical Use 1. Scope 1.1 This Standard outlines basic safety and performance requirements for anaesthetic machines and components thereof for use with humans. 1.2 The requirements of this Standar
37、d are intended to enhance patient safety. 1.3 This Standard excludes requirements for anaesthesia ventilators (see CSA Standard CAN/CSA-Z168.5.1. 1.4 This Standard excludes specific provisions for (a) anaesthetic machines equipped to deliver flammable anaesthetics agents; (b) draw-over vaporizers; (
38、c) dental nitrous oxideloxygen analgesia machines; (d) breathing circuits; and (e anaesthetic gas scavenging systems. 2. Definitions and Reference Publications 2.1 Definitions The following definitions apply in this Standard: Anaesthetic machine - equipment for dispensing and delivering medical and
39、anaesthetic gases and vapours into a breathing system. Anaesthetic vaporizer - a device designed to facilitate the change of an anaesthetic agent from a liquid to a vapour. Breathing system - those gas pathways continuously or intermittently in communication with a patients respiratory tract during
40、any form of ventilation. Check valve - an automatically actuated valve that prevents reverse flow of gas. Common gas outlet - the port through which the dispensed mixture from the anaesthetic machine is delivered to the breathing system. Flow control valve - a device that controls the flow of a gas
41、through its associated flowmeter by manual adjustment. March 7997 1 Z I 68.3-97 Flowmeter (fIow metering device) - any device that indicates the volume of a specific gas or gas mixture passing through it in a unit of time. Gas mixing device (gas mixer) - a device that receives separate supplies of o
42、xygen and other medical gas(es), and deIivers the mixed gases in concentrations adjustable by the operator. Hypoxic mixture - a mixture of medical gases that contains less than 21% oxygen. Room temperature and pressure (RTP) - ambient conditions of 20C and 109.3 kPa (absolute). Note: Unless otherwis
43、e specified, pressure vahes are referred to in ambient atmospheric pressure. 2.2 Reference Publications This Standard refers to the following publications and where such reference is made it shall be to the edition listed below.
