After completing the salt spray test, it is essential to properly manage the residual mist and waste water. The system should be treated appropriately before discharging the mist through the building’s exhaust outlet and directing the waste water into the drainage system. This ensures safety, environmental compliance, and the longevity of the testing equipment. Proper maintenance and adherence to the standard are crucial for accurate and repeatable results.
