Test procedure
- As AATCC 22 required, we put the test piece to the humidifying treatment more than 4 hours, which under the environment of standard temperature of21±1℃and relative humility of 65±2℃.
- After the humidifying treatment, the test piece clamped by the holder on the support at a 45°, and we pure 50ml water into the funnel rapidly steadily in order to keep drenching constantly. When the water is used up, we can observe the test piece.
- According to description of spray rating to assess its grade of wet but without the intergrade.
Spray rating
- ISO 0 = AATCC 0: complete wetting of the entire face of the sample.
- ISO 1 = AATCC 50: complete wetting of the entire sample face beyond the spray points.
- ISO 2 = AATCC 70: partial wetting of the sample face beyond the spray points.
- ISO 3 = AATCC 80: wetting of specimen face at spray points.
- ISO 4 = AATCC 90: slight random sticking or wetting of the specimen face.
- ISO 5 = AATCC 100: no sticking or wetting of the specimen.
Test result
The test result should include the following message:
- The illustration of the test procedure according to the standard.
- Atmospheric conditions.
- Water temperature.
- Spray rating of each test piece.
- Experimental date.
