8.1 Operating Requirements. To comply with this standard, any production unit shall meet the minimum operating requirements detailed in this section. 8.2 Water-Trace Test. Self-Contained Humidifiers shall pass a water-trace test for each class designation as specified in the manufacturer’s installation instructions when operated at Standard Rating Conditions specified in 6.2. 8.2.1 Procedure. The Self-Contained Humidifier shall operate for the duration of the Standard Rating test.
8.2.2 Requirements.
8.2.2.1 During the test, water shall not drip or run off the Self-Contained Humidifier under test.
8.2.2.2 After the test, the surface under or surrounding the Self-Contained Humidifier shall be dry, provided that the surface temperature exceeds 42°F [5.6°C].
8.3 Water Flow Control Test. Self-Contained Humidifiers shall pass the following water flow control test when operated at Standard Rating Conditions specified in 6.2 except for water pressure conditions.
8.3.1 Water Pressure Conditions. Water pressure conditions shall be maintained at 20 psi [140 kPa].
