2、This method is used to determine the non-volatile content of paints, essentially that which is suspended or dissolved in water. Apparatus Required Mechanical Convection Oven Capable of maintaining a constant temperature of 175 +/- 2 C. Mechanical Convection Oven Capable of maintaining a constant tem

3、perature of 105 +/- 2 C. Analytical Balance Precision +/- 0.0001 g Pipette or Spoonspatula Aluminum Weighing Dishes (45 mm diameter) Desiccator With drying agent (e.g. Drierite) Conditioning and Test Conditions All test values indicated herein are based on material conditioned in a controlled atmosp

4、here 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. FORD LABORATORY TEST METHOD BI 120-08 Page 2 of 2 Copyright 2001, Ford Global Technologies, Inc. Procedure 1. Stir the sample of paint thorough

5、ly. 2. Dry three clean aluminum dishes to constant weight and record the weights. 3. Transfer approximately 1 g of the sample to each weighing dish. Spread the paint evenly over the bottom surface and reweigh immediately. Record weights. 4. Preheat the dishes and contents for 60 minutes at 105 +/- 2

6、 C, then transfer to another oven for 30 minutes at 175 +/- 2 C. 5. Cool the dishes to 23 +/- 2 C in the desiccator and reweigh. Evaluation Calculate the non-volatile content according to the following formula and report the results as the average value of the 3 specimens: Non-volatile content % = w

7、eight of residue x 100 initial weight of sample Note: If the individual results of the three specimens differ from each other by more than 2 %, repeat the procedure. With specimens which contain up to 20 % non-volatiles, the individual results must not differ more than 1 %. 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.
