CIRM Standards Guide
This is CIRM's guide to the international performance standards and testing requirements applying to bridge navigation and communication equipment.
NOTE: This guide provides a high-level overview of applicable standards for quick reference; it is not intended to be an exhaustive list of all testing requirements applying to equipment. Further testing requirements may apply to equipment, for example where listed in the EU Marine Equipment Directive (MED).
