ISO5356-1 Anaesthetic Respiratory Equipment / Conical Connectors Test Equipment

ISO5356-1 Anaesthetic and respiratory equipment — Conical connectors Test equipment

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 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 ± 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.
