5、nditions All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. Procedure Prepare test specimen in line with
6、relevant Material or Performance Specifications. After the required ageing period all test parts must be cross hatched with an “Andreas Cross“ (30 angle) down to substrate. 1. The equipment is filled with water without any additional cleaning agents and heated to 80 +/- 2 C. 2. Before testing the eq
7、uipment must be adjusted to the required test pressure for the specified distance. 3. The gun with the nozzle is fixed to the required distance from the nozzle to the painted surface which is to be tested. The jet of water has to be directed vertically onto the painted surface. 4. Spray water for th
8、e specified length of time. 5. The surface is dried and evaluated after cooling to 23 +/- 2 C. 6. Report any failure (e.g., loss of gloss, loss of adhesion, surface deterioration). Chemicals, materials, parts, and equipment referenced in this document must be used and handled properly. Each party is responsible for determining proper use and handling in its facilities.
