14、(the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical comm
15、ittee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrote
16、chnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the memb
17、er bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifyi
18、ng any or all such patent rights. ISO 5356-1 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment,Subcommittee SC 1, Breathing attachments and anaesthetic machines.This third edition cancels and replaces the second edition (ISO 5356-1:1996), which has been technicall
19、y revised. The major differences are the inclusion of 8,5 mm size connectors and some minor corrections to the figures and tables. ISO 5356 consists of the following parts, under the general title Anaesthetic and respiratory equipment Conical connectors: Part 1: Cones and sockets Part 2: Screw-threa
20、ded weight-bearing connectors Approved as an American National Standard with deviations by ASTM InternationalANSI/ISO 5356-1:2004(E) ASTM International vIntroductionIn clinical practice, several breathing attachments used in anaesthetic and respiratory equipment may have to be joined together to pro
21、vide a suitable breathing system. Items of medical equipment, such as a humidifier or a spirometer, are often incorporated into the breathing system which may also be connected to an anaesthetic-gas scavenging system. Connections for these purposes are usually cone and socket joints, and a lack of s
22、tandardization of these connections has given rise to problems of interchangeability when connecting equipment made by different manufacturers. This part of ISO 5356 specifies the requirements and dimensions for conical connectors used in anaesthetic and respiratory equipment. An important considera
23、tion is that conical connections need to be secure but nevertheless disconnectable by the operator. The use of connectors meeting the requirements of this part of ISO 5356 will not necessarily prevent them being disconnected accidentally. To minimize the risk of 22 mm connectors being accidentally d
24、isconnected, latching connectors can be used. Annex A includes a figure and a table detailing plug and ring test gauges that are used to check conical connectors made of materials other than metal. Annexes B, C and D provide test methods for latching connectors, Annex E includes a figure and table d
25、etailing plug and ring test gauges that may be used to check metal conical connectors, and Annex F contains recommendations for testing security of latching connectors. Figure 1, detailing the dimensions and tolerances of metal conical connectors, has been prepared in accordance with ISO 3040. Appro

27、s for cones and sockets intended for connecting anaesthetic and respiratory equipment, e.g. in breathing systems, anaesthetic-gas scavenging systems and vaporizers. This part of ISO 5356 gives requirements for the following conical connectors: 8,5 mm size intended for use in paediatric breathing sys
28、tems; 15 mm and 22 mm sizes intended for general use in breathing systems; 22 mm latching connectors (including performance requirements); 23 mm size intended for use with vaporizers, but not for use in breathing systems; 30 mm size intended for the connection of a breathing system to an anaesthetic
29、 gas scavenging system. This part of ISO 5356 does not specify the medical devices and accessories on which these connections are to be provided. Requirements for the application of conical connectors are not included in this part of ISO 5356, but are or will be given in the relevant International S
30、tandards for specific medical devices and accessories. NOTE Requirements for screw-threaded weight-bearing conical connectors are specified in ISO 5356-2. 2 Normative references The following referenced documents are indispensable for the application of this document.

36、tended to attach a face mask shall incorporate a shoulder or equivalent construction as shown in Figure 2 b). 4.2.3 If a circumferential groove or grooves are incorporated in the surface of a male conical connector of 22 mm size, the total width of the groove or grooves at the surface shall not exce
37、ed 8 mm. The radius on the entrance to the female connector and on the leading edge of the male cone should be not less than 0,5 mm and not more than 0,8 mm.

41、al connectors of 8,5 mm size The male conical connector shall have a minimum inside diameter of 6 mm extending inward for at least 6 mm from the end of the connector. 5 Conical connectors made of materials other than metal 5.1 General requirements Conical connectors made of materials other than meta
42、l shall meet the following requirements when they are type-tested with gauges having dimensions as shown in Figure A.1 and Table A.1. a) Conical connectors made of materials other than metal shall meet the dimensional requirements in Figure 1 and Table 1, with the exception than dimensions A and B a
43、nd ratio F may vary from those shown. b) When the connector is engaged in the appropriate plug or ring test gauge shown in Figure A.1 and Table A.1, by applying an axial force of (35 r 3,5) N for 8,5 mm and 15 mm connectors and (50 r 5) N for 22 mm and 30 mm connectors and, while maintaining the sam
44、e force, rotating the connector up to 20, its leading edge shall lie between the minimum and maximum diameter steps of the gauge. The connectors and gauges shall be maintained at a temperature of (20 r 3) C during the test. NOTE Because connectors made from plastics materials, for example polyamide,
45、 polyacetal, polycarbonate, polysulfone, etc., can vary greatly in their physical characteristics, it is not considered practicable to specify their dimensions; for this reason, gauging requirements have been included. It is also considered impracticable to generalize on matters such as cold flow an
46、d thermal instability, as well as possible changes in physical characteristics, contact with solvents, etc. It is the responsibility of the manufacturer to ensure that adequate tests have been carried out to prove as far as possible that the particular materials chosen for the connectors are suitabl
