      The compressed air supply to the nozzle or nozzles for atomizing the salt solution shall be free of oil and dirt, and maintained at a pressure between 70 kN/m2 and 170 kN/m2.

5. Conditions in the mist chamber

      5.1. The exposure zone of the mist chamber shall be maintained at 35 + 5° C.  At least two clean mist collectors shall be placed within the exposure zone so that no drops of solution from the test samples or any other sources are collected.  The collectors shall be placed near the test samples, one nearest to any nozzle and one furthest from all nozzles.  The mist shall be such that for each 80 cm2 of horizontal collecting areas, there is collected in each collector from 1.0 to 2.0 ml of solution per hour when measured over an average of at least 16 hours.

      5.2 The nozzle or nozzles shall be directed or baffled so that the spray does not impinge directly on test samples.
