1 Scope and field of application

 This appendix gives directions for measuring nominal air change and air distribution in connection with testing of ventilation plants in ro-ro ships cargo spaces where running of vehicles with internal combustion engines occurs.

The nominal air change is measured by calculation of the air flow in supply air and exhaust air terminal devices. The air distribution is normally estimated visually with visible smoke, or by measuring with tracer gas.
