Appendix A

(Normative appendix) Testing method A.1 Warning Some of the test procedures specified in the test method may result in a hazardous situation. Operators should take appropriate safety and protective measures. A.2 General provisions Unless otherwise stated, only the reagents identified as analytical reagents and the tertiary water specified in GB/T 6682-2008 are used in the analysis. The preparation and preparation used in the test method shall be prepared according to the provisions of GB/T 603 when no other requirements are specified. A.3 Identification test A.3.1 Methodological Summary The azeotrope formed by the morpholine and water in the sample should be basic, and the animal and plant wax is dissolved in carbon tetrachloride and the animal and plant gum is in the sulfuric acid medium. Ammonium molybdate reaction should be green. A.3.2 Reagents and materials A.3.2.1 Ammonium molybdate. A.3.2.2 Carbon tetrachloride. A.3.2.3 Sulfuric acid. A.3.2.4 Hydrochloric acid solution. 1 1. A.3.2.5 Sodium hydroxide solution..200 g/L. A.3.2.6 phenolphthalein indicator solution. 10g/L. A.3.3 Analysis steps A.3.3.1 Identification of animal and plant wax as a film-forming agent A.3.3.1.1 Weigh about 10g of laboratory samples, accurate to 0.1g, add 20mL hydrochloric acid solution, in the water bath for 10min. cool down To room temperature, the solid matter A is isolated. Sodium hydroxide solution was added to the residue to make it alkaline and then distilled. Collect 102 ℃ ~ 104 ℃ distillation Points, plus 1 drop of phenolphthalein indicator solution, should be pink. A.3.3.1.2 Weigh solid A in about 1gA.3.3.1.1 In a beaker, add 5mL of carbon tetrachloride, heat it on a water bath, solid A Dissolve. A.3.3.2 Identification method of animal and plant gum as film forming agent A.3.3.2.1 Operation with A.3.3.1.1. A.3.3.2.2 Weigh about 1gA.3.3.2.1 Solid A in the beaker, add 1g of ammonium molybdate and 3mL sulfuric acid solution after a few drops Green. A.4 Determination of solid matter A.4.1 Analysis steps Weigh about 2g of laboratory samples, accurate to 0.0002g, placed in the 500 ℃ ~ 600 ℃ burning to the constant quality of 50mL porcelain crucible , Placed in an electric oven, dried at (95 ± 2) ° C to a constant mass. Retention solid B is used for the determination of burning residue. A.4.2 Result calculation The mass fraction of solid, w1, is expressed in% and is calculated as in equation (A.1) w1 = m2m1 × 100% (A.1) Where. m1 --- the mass of the sample, in grams (g); m2 - the mass of the solid, in grams (g). The arithmetic mean of the results of two parallel measurements is the result of the report. The absolute difference between the two parallel determinations is not more than 0.8%.

A.8 Cold stability test In two 50 mL colorimetric tubes, add the laboratory sample to the scale. One into the low temperature bath, at (-2 ± 0.2) ℃ Paul After taking 4h, remove and rinse to room temperature. The other is placed at room temperature. Visual inspection of the two colorimetric tubes in the test solution, the transparency should be no significant difference. 0102-
