Evaporation Residue Testing Evaporation residue test is to measure the dissolved part mass of materials in different solutions. By further analysis for evaporation residue, the safety of packaging materials can be greatly ensured.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 Residue on Evaporation Test (water analysis) : Evaporate 100 ml to dryness on a water bath and dry to constant weight at 105°C. The residue weighs not more than 1 mg (0.001%). Heavy Metals Test (water analysis) : Determined by Method D on 12 ml of a solution prepared in the following manner. 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).
