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 relevant International Standards for specific medical devices and accessories.
NOTE Requirements for screw-threaded weightbearing connectors are specified in ISO 5356-2.

ISO 5367:2014, Anaesthetic and respiratory equipment一Breathing sets and connectors
Cones and sockets made of non- metallic materials shall comply with Figure 1 and the dimensions given in Table 1 except that the dimensions A and B and ratio F may vary from those given in Table 1.Check compliance by engaging the cone or socket in the appropriate plug or ring test gauge according to Eigure A.1 and Table A.1 by applying an axial force of (35 t 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 rotating 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 t 3)。C during the test.
NOTE Because cones or sockets made from plastics materials (for example polyamide, polyacetal,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 and thermal instability, as well as possible changes in physical characteristics, contact with solvents, etc.
22 mm cones designed to connect to a breathing tube complying with ISO 5367:2014, 5.3.2.2, or a latching socket (see Clause 4) shall incorporate a recess, the dimensions of which are given in Figure 2.BS EN ISO 5356-1 pdf free download.
