Summary of method. 2.1 A volume of filtered sample that will yield less than 200 mg residue is evaporated just to dryness on a steam bath. The residue is dried at 105°C for 2.0 h, cooled in a desiccator, and immediately weighed.This analysis determines the mass of the residue left behind when the water in the sample is evaporated at different temperatures.

Applications. Applications. Applicable to tableware, food containers, packaging films, bags, cap sealing rubber pad, painted .
1.1 This test method covers the determination of the amount of carbon residue (Note 1) left after evaporation and pyrolysis of an oil, and is intended to provide some indication of relative coke-forming propensities.This test method is generally applicable to relatively nonvolatile petroleum products which partially decompose on distillation at atmospheric pressure.
3.1.1 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. Summary of Test Method 4.1 A weighed quantity of sample is placed in a glass vialMODEL : HGT 915 & 917: Gum Test; SPECIFICATION : Measure evaporation residue in aviation fuels, motor gasolines, and other volatile distillates. > The HGT 915 uses air evaporation, while the HGT 917 offers the versatility of either air or steam evaporation. > Both models are capable of testing three 100 ml samples simultaneously. 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 residue is not composed entirely of carbon, but is a coke which can be further changed by pyrolysis. The term carbon residue is continued in this test method only in deference to its wide common usage. Note 2—Values obtained by this test method are not numerically the same as those obtained by Test Method D 189, or Test Method D 4530 .

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.This test method describes the procedure to determine the percentage of asphalt and latex (combined) in an asphaltic emulsion. The residue from this test may then be used for additional testing. This test is a modification to Section 7 of AASHTO T 59-15. B. REFERENCES AASHTO T 59 -15 – Standard Test Method for Emulsified Asphalts
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. PRECAUTIONS 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.The TOC vials were placed open under an extractor hood to assist evaporation without inputting external contamination. Despite all these precautions, and in order to take account of potential carbon contamination appearing during sample evaporation, sample blanks were also prepared and left to evaporate beside the test samples.

Categories: Evaporation Residue Testing Overview ERT-01 Evaporation Residue Constant Weight Tester is professionally designed for the precisely quantitative determination of dissolved substances of table wares, containers, packaging films, cans, tubes and other food-use equipments in different soaking solutions.Solids, residue on evaporation at 105°C, total, gravimetric Parameter and Code: Solids, residue on evaporation at 105°C, total, I-3750-85 (mg/L): 00500 1. Application 1.1 This method may be used to determine the total-solids concentration of any natural or treated water or industrial waste. 1.2 Total residue represents the sum of both In geology there is a streak test where a mineral is rubbed on a alumina plate to create microscopic particles. The streak test often yields colors that are different than that of the "massive" specimen. In this case copper sulfate pentahydrate will have a white steak because of the small particle size and light coloring.
This test method quantifies soluble organic compounds (hydrocarbon materials), sometimes called ‘evaporation residue’, which can be present in liquefied petroleum gases and which are substantially less volatile than the LPG product, i.e. with a boiling point between 174 °C and 522 °C (C10 to C40). Cooling and weighing the residue: After evaporation, the dish is allowed to cool to room temperature in a desiccator and then re-weighed to determine the weight of the nonvolatile residue. Calculation: The nonvolatile matter content is calculated by dividing the weight of the nonvolatile residue by the weight of the original sample and .

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%). The NaOH they add to it is to prolong shelf life. And the reaction by which sodium hypochlorite is reduced to sodium chloride consumes protons, producing even more hydroxide, so it's indeed possible that residual alkali is causing the irritation the OP is describing.
