ISO 5356-2 Test Standard for Anesthetic and Respiratory Equipment, Conical Connectors, Screw Thread Weight-Bearing Connectors

This part of ISO 5356 specifies requirements for the following threaded, weight-bearing tapered connectors:

  • 22mm connectors;
  • 22mm/15mm coaxial connectors;

The requirements for the application of threaded, weight-bearing tapered connectors are not contained in this part of ISO 5356, but are or will be given in the relevant international standards for certain medical devices and accessories.

Factors regulating the design of these connectors include robustness, simplicity, ease of sterilization, and ease of manual assembly and separation. It must also be compatible with connectors that meet the requirements described in the ISO 5356-1 standard.
