19、l breathing attachments used in anaesthetic and respiratory equipment may have to be joined together to provide a suitable breathing system. Items of medical equipment, such as a humidifier or a spirometer, are often incorporated into the breathing system which might also be connected to an anaesthe
20、tic gas scavenging system. Connections for these purposes are usually cone and socket joints, and a lack of standardization of these connections has given rise to problems of interchangeability when connecting equipment made by different manufacturers. This part of ISO 5356 specifies the requirement
21、s and dimensions for cones and sockets used in anaesthetic and respiratory equipment.An important consideration is that conical connections need to be secure but nevertheless disconnectable by the operator. The use of cones and sockets meeting the requirements of this part of ISO 5356 will not neces
22、sarily prevent them being disconnected accidentally. To minimize the risk of 22 mm connectors being accidentally disconnected, latching sockets can be used.Annex A includes a figure and a table detailing plug and ring test gauges that are used to check cones and sockets made of materials other than
23、metal. Annex B, Annex C, and Annex D provide test methods for latching sockets, Annex E includes a figure and table detailing plug and ring test gauges that can be used to check metal cones and sockets, and Annex F contains recommendations for testing the security of latching sockets.Figure 1, detai

25、type. ISO 2015 All rights reserved vBS EN ISO 5356-1:2015Anaesthetic and respiratory equipment Conical connectors Part 1: Cones and sockets1 ScopeThis part of ISO 5356 specifies dimensional and gauging requirements for cones and sockets intended for connecting anaesthetic and respiratory equipment,
26、e.g. in breathing systems, anaesthetic gas scavenging systems, and vaporizers. The cones and sockets are therefore not regarded as devices in their own right.This part of ISO 5356 gives requirements for the following cones and sockets: 8,5 mm and 11,5 mm sizes intended for use in neonatal and paedia
27、tric breathing systems; 15 mm and 22 mm sizes intended for general use in breathing systems; 22 mm latching sockets (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
28、 an anaesthetic gas scavenging system.This part of ISO 5356 does not specify the medical devices and accessories on which these cones and sockets are to be provided.Requirements for the application of cones and sockets are not included in this part of ISO 5356, but are or will be given in the releva
29、nt International Standards for specific medical devices and accessories.NOTE Requirements for screw-threaded weight-bearing connectors are specified in ISO 5356-2.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for
30、 its application. For dated references, only the edition cited applies.

33、e 1.Check compliance by engaging the cone or socket in the appropriate plug or ring test gauge according to Figure A.1 and Table A.1, by applying an axial force of (35 3,5) N for 8,5 mm, 11,5 mm, and 15 mm cones or sockets and (50 5) N for 22 mm and 30 mm cones or sockets while simultaneously rotati
34、ng the cone or socket (20 5). Its leading edge shall lie between the minimum and maximum diameter steps of the gauge. The cones or sockets and gauges shall be maintained at a temperature of (20 3) C during the test.NOTE Because cones or sockets made from plastics materials (for example polyamide, po
35、lyacetal, polycarbonate, polysulfone) can vary greatly in their physical characteristics, it is not considered practicable to specify dimensions A, B, and ratio F; for this reason, gauging requirements have been included. It is also considered impracticable to generalize on matters such as cold flow
36、 and thermal instability, as well as possible changes in physical characteristics, contact with solvents, etc.BDECAGaHFFaFor the 8,5 mm cone and the 30 mm cone, dimension G over the minimum length, H, as specified in Table 1.NOTE The radius on the entrance to the socket and on the leading edge of th
