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.

The test result should include the following message:

  1. The illustration of the test procedure according to the standard.
  2. Atmospheric conditions.
  3. Water temperature.
  4. Spray rating of each test piece.
  5. Experimental date.
