The device shall consist of a tank having sufficient capacity to accumulate the flow for at least two minutes and shall be located so that the liquid leaving the coil under test can be diverted into it.

Leaving air wet-bulb temperatures are not chamber and downstream from the nozzle plate. After commissioning of the test stand and after refrigerant changes, as applicable, the lubricant circulation rate on the sample basis shall be measured and verified.

The height of the coil is the dimension of the face of the coil perpendicular to the direction of the tubes and includes only the height over tubes and fins exposed to the flow of air.
