Test method
HG2253-91
This test Unless otherwise specified, the standard solutions, preparations and products used in the impurity determination method are prepared according to the provisions of GB602 and GB603. The laboratory water should meet the third-grade water specifications in GB6682. 4.1 The determination of the content of the color former COY-2 (CHsCIN,O) shall be determined according to the provisions of HG/T2414, in which the main content of the standard sample shall not be less than 98%, and the control sample is composed of the color former COY-2 and its intermediate amino and chloride in a ratio of 2:1:1. 4.2 The solubility test
shall be determined according to the provisions of HG2258. The test solution should be transparent and a trace of insoluble matter is allowed. 4.3 The determination of volatile matter
shall be determined according to the provisions of HG2257. The volatile matter content should be less than 10mg after drying at a temperature of 100~105℃. 4.4 The determination of ash
shall be determined according to the provisions of HG2256. The ash content should be less than 3 mg (keep the ash residue for iron determination). 4.5 Determination of iron impurities
Add 1 mL of hydrochloric acid to the ash residue in 4.4, dissolve it in warm water, add 10 mL of water and transfer it to a 25 mL volumetric flask, dilute it to the scale with water, shake it well, transfer 5 mL of the above sample solution, place it in a 50 mL colorimetric tube, add about 30 mg of ammonium persulfate and 5 mL of ammonium thiocyanate solution (100 g/L), dilute it to the scale with water, and mix it well. The color of the sample solution shall not be darker than the standard. The standard is to take 0.01 mg of iron (Fe) impurity standard solution and treat it in the same way as the sample. 4.6 Photographic performance test
Test according to the method agreed upon by the supply and demand parties. 4.7 Infrared spectrum identification
Place about 1.5 g of the sample in an agate mortar and grind it into 2μm powder. Add about 100 mg of dried spectrally pure potassium bromide fine powder, grind it thoroughly with an agate mortar, mix it and dry it, press it into a transparent thin sheet on a tablet press, and measure it on an infrared spectrophotometer within the wavenumber range of 4000~400cm1. The obtained infrared spectrum should be consistent with the infrared spectrum of the standard sample. The figure is consistent with the inspection rules. 5 Inspection rules
Sampling and acceptance shall be carried out in accordance with the provisions of GB619. 6 Packaging, marking, transportation and storage
6.1 Packaging
The inner packaging of the packaging unit 20kg should be a double-layer plastic bag, which should be tied. The outer packaging should be a fiberboard barrel. If special packaging is required, it shall be decided by negotiation between the supply and demand parties
6.2 Marking
The outer packaging container shall be painted with a firm mark, indicating the product name, standard number, registered trademark, net weight, gross weight, production batch number, photographic chemicals and factory date, manufacturer name and address, and a moisture-proof mark. The packaging container shall be accompanied by a quality inspection certificate. 6.3 TransportationbZxz.net
Be careful during transportation, prevent moisture and heat, and do not damage the packaging. 6.4 Storage
The product should be stored in a cool, dry and ventilated warehouse. The storage period is 1 year. After the expiration of the period, the product shall be inspected according to the provisions of this standard. If the product meets the requirements of this standard, it may continue to be used. 2
