Test method
General provisions: reagents and water used in this standard refer to analytical reagent and Grade III water specified in GB/T6682-2008, unless other requirements are specified. The standard titration solution, impurity standard solution, preparation and products used in the test shall be prepared according to HG/T3696.1, HG/T3696.2 and HG/T3696.3 when no other requirements are specified.
Appearance inspection: under natural light, the appearance of the body sample is determined by visual method on a watch glass or white porcelain plate on a white substrate; The liquid sample is packed in the sample, and the appearance is determined by visual method on the white substrate under natural light.
