2、e effects of a condensing water atmosphere on treated panels. The nature of this test requires that it be used on flat panels which form a roof for the condensing fog. Apparatus Required Cleveland Condensing Cabinet Source: Q-Panel Co. 15610 Industrial Parkway Cleveland, OH 44135 (216) 267-9200 Glas

3、s Panels - 100 x 200 mm Glass panels are required as blanks. Stainless steel is not recommended due to possible galvanic corrosion. Conditioning and Test Conditions All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relative hum

4、idity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. Procedure “A“ 1. Panels to be tested are placed on the frame provided to act as a roof of the condensing cabinet. 2. The roof frame shall be inclined at 60 unless otherwise specified. 3. Ai

5、r temperature inside the cabinet shall be maintained at 43 +/- 2 C. 4. Air temperature of panel back shall be 23 +/- 2 C.

6、 to “Hi“ position. Set operating temperature with thermostat control. 6. Place panels to be tested on the rack provided. All slots must be covered with test panels or glass blanks. Panels should be placed so that dissimilar metals do not touch in order to eliminate galvanic action. 7. Expose the pan

7、els to the number of hours of wet condensate as indicated in the applicable Engineering Materials Specification. Blow off condensate with air to remove condensate and examine for occurrence of film failure, i.e. dulling, blistering or loss of adhesion. Procedure “B“ This procedure differs from the p

8、receding in that the panels are exposed to alternating cycles of condensation and drying. 1. Perform Steps 1 thru 6 as indicated previously. 2. Expose the panels for 23 hours to condensing humidity and for 1 - 2 hours of drying by setting automatic dry-off times with timer, and dry-off air temperatu

9、re with dry-off heat input control. 3. Manual dry-off can be accomplished by removing test frame or placing panels on T-bar to dry. 4. Continue test by replacing panels on frame and re-exposing to condensate. 5. Panels shall be cycled, wet and dry, as required, and examined for film failure. 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.
