2、operties of adhesives and sealers. These properties can be used to determine the amount of flow required to structurally bond metal-to-metal components, such as the inner and outer panels of doors. Apparatus Required Scale A scale equipped with a minimum readability of 0.1 g. Oven An oven capable of
3、 achieving temperatures of 35 C to 185 C Materials Required Adhesive Material obtained from requestor Test Panels Oiled 60E steel panels, with dimensions of 4“ x 12“ Conditioning and Test Conditions All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +
4、/- 4 C and 50 +/- 5% relative humidity for not less than 24 h prior to testing. Materials will be tested at the following temperatures: 35 C, 40 C, 50 C, 55 C, 60 C and 65 C. Procedure 1. Place a 3 cc volume daub on the top of a 4“ x 12“ oiled steel test panel. Daub volume should be measured on a sc
5、ale, using specific gravity to convert from weight to volume. See Figure 1 for placement of daub onto test panel. A minimum of 43 test panels, with one 3 cc daub per panel, are required. 2. Place one panel vertically (with daub on top) into a 180 C oven for 30 minutes. Remove panel and record the fl
6、ow, from the top of the daub to the bottom edge of the flow. Record this as Initial. See Figure 2 for flow measurement details. 3. Place seven test panels vertically (with daub on top) into a 35 F oven. 4. After one day (24 hours), remove panel and place into a 180 C oven for 30 minutes. Remove pane
7、l and record the flow, from the top of the daub to the bottom edge of the flow. Record this as One Day. See Figure 2 for flow measurement details.

8、ays, three days, four days, five days, six days and seven days in a 35 C oven. 6. Repeat steps 3, 4 and 5 at the following oven temperatures: 40 C, 50 C, 55 C, 60 C and 65 C. No movement or flow after baking in a 180 C oven should be recorded as No Flow. An example of a “No Flow panel is shown in Fi
9、gure 3. Testing at a given temperature can be stopped once the No Flow condition is reached. 7. At the lower temperatures (35 C, 40 C, 50 C), a No Flow condition may not be reached in seven days. In this case, continue testing on a daily basis, until the No Flow condition is reached. 8. Record all o
