The Japanese Food Sanitation Act designates the evaporation residue test as a specification for plastics that intended to contact with foods. The test conditions and migration limits for oils and fatty foods were considered on the basis of the results obtained from the evaporation residue test according to the Japanese Act and the overall migration test into olive oil according to . Test solution-Take 12 ml of the solution prepared in the following manner in a glass evaporating dish evaporate 150 ml to 15 ml in a water bath. . 12.0 RESIDUE ON EVAPORATION: Evaporate 100 ml of sample to dryness on a water-bath and dry to constant weight at 105°C. The residue weight not more than 1 mg (0.001%). 3.2 This test method for residue by evaporation tends to give an asphaltic residue lower in penetration and ductility than the distillation test method (D6997).Material may be accepted but shall not be rejected as failing to meet specifications containing requirements for determination of residue by distillation, on data obtained by evaporation.

1.1 This test method covers the determination of dissolved organic and inorganic matter and colloidal material found in high-purity water used in the semiconductor, and related industries. This material is referred to as residue after evaporation (RAE). The range of the test method is from 0.001 μg/L (ppb) to 60 μg/L (ppb).3.1 The test may be used to indicate compositional charac-teristics of emulsified asphalt. Evaporation residue may also be subjected to other characterization tests. 3.2 This test method for residue by evaporation tends to give an asphaltic residue lower in penetration and ductility than the distillation test method (D6997). Material may be . The term “SAP” in the context of acetic acid glacial testing likely refers to the “Saponification Value” or “Saponification Acid Value.” The Acetic Acid Glacial Testing Procedure (SAP) saponification value is a measure of the average molecular weight of all the fatty acids present in a substance. It is often used in the analysis of fats and oils.
1. Calculate the percentage of residue for each sample, as follows: Residue, % = 4 × (M a -M b) where: M a = Weight of the container and asphalt emulsion residue in grams, and M b = Tare weight of the container in grams. F. REPORTING OF RESULTS Report the percentage of residue by evaporation as the average of the three results. G. PRECAUTIONS3.1.1 carbon residue, n—the residue formed by evaporation and thermal degradation of a carbon containing material. 3.1.1.1 Discussion—The residue is not composed entirely of carbon but is a coke that can be further changed by carbon pyrolysis. 4.
