Overview

Respiratory system accessories from anaesthesia and respiratory equipment are connected using conical connections. Part 1 of the DIN EN ISO 5356 series specifies the dimensions for the following conical connections for this purpose - 8,5 mm and 11,5 mm sizes intended for use in neonatal and paediatric 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 an anaesthetic gas scavenging system. The technical amendments made in the new edition of the standard concern in particular - inclusion of 11.5 mm connectors, which are used for children and newborns; - definition of the internal diameter for the 30 mm cone; - the internal diameter of the 8,5 mm cone has been changed from 6,0 mm to 6,25 mm; - dimension D in Annex A for the plug and ring test gauges for 8,5 mm cones and sockets made of materials other than metal has been changed to (1,91 ± 0,005) mm. The standard has been prepared by CEN/TC 215 "Respiratory and anaesthetic equipment") (secretariat: BSI, United Kingdom) with the participation of ISO/TC 121/SC 1 "Breathing attachments and anaesthetic machines" (secretariat: DIN, Germany). The responsible German committee is Working Committee NA 053-03-01 AA "Anästhesie und Beatmung" ("Anaesthesia and respiration") at Standards Committee Rescue Services and Hospital (NARK) at DIN.
