Introduction
JB/T103832002
Rivet electric contacts are the most widely used products in my country's electric contact industry. They are mainly used in various relays, contactors and household appliances. Their quality determines the quality and reliability of the appliances to a large extent. my country's electric contact industry originally implemented ZBK14002-1988 "Silver/Copper Bimetallic Composite Rivet Electric Contact Technical Conditions" (this standard was abolished during the review in 1997) and the national standard GB/T11096-1989 "Precious Metals and Their Alloys Rivet Type Composite Electric Contact Materials" (this standard has been adjusted to the non-ferrous metal industry standard after review). However, with the development of production and technology in my country's electrical contact industry, the varieties and specifications of rivet electrical contact products are increasing. The standard "precious metal and its alloy rivet type composite electrical contact materials" is only applicable to some precious metal and its alloy composite rivet electrical contacts, and cannot cover dozens of varieties of composite rivet electrical contacts currently produced by my country's electrical contact industry. In addition, there is no current standard for integral rivet electrical contacts. In order to meet the needs of rivet electrical contacts production and use, the National Electrical Alloy Standardization Technical Committee proposed and formulated this standard. 1 Scope

Method for determination of Ce content in AgCe
This method specifies the determination of Ce content in AgCe by azobenzene III colorimetry. This method is applicable to the determination of Ce content in AgCe, with a determination range of 0.01% to 1.00%. A.2 Method Summary
The sample is dissolved in nitric acid, and silver is pickled with thiourea in the presence of a buffer solution. At pH 2.8, the silver is directly determined by color development using azobenzene II.
A.3 Reagents
A.3.1 Nitric acid: specific gravity 1.42 and (1+1). A.3.2 Sulfuric acid: (1+1).
A.3.3 Thiourea: 10% (prepared on the same day). A.3.4 Acetic acid-sodium acetate buffer solution: Mix 20g sodium acetate and 400mL glacial acetic acid to dissolve, then dilute with water to 1L (filter if turbid). The pH of this solution is 2.8 (adjust on the acidometer). A.3.5 Thymol blue indicator (0.1%): Dissolve 0.1g reagent in 4.30mL sodium hydroxide (0.05N) solution, and dilute with water to 100mL. A.3.6 Ammonia water: (1+4).
A.3.7 Azobenzene IIIIII: 0.05% aqueous solution. A.3.8 Antimony standard solution: Weigh 0.1228g of spectrally pure antimony dioxide into a 250mL conical flask, add 10mL water, 5mL hydrogen peroxide (30%), and 15mL sulfuric acid (1+1), heat to dissolve, boil and evaporate until white smoke appears. Cool to room temperature, transfer to a 1000mL volumetric flask, dilute to scale with water, and shake well. 1mL of this solution = 0.1mg of styrene. Pipette 10.00mL of the above solution into a 100mL volumetric flask, dilute to scale with water, and shake well. 1mL of this solution = 0.01mg of styrene. A.4 Analysis method
Weigh 0.2500g of the sample into a conical flask, add 5mL of nitric acid (1+1), and after the sample is completely dissolved, heat and boil to remove the hydroxide, remove it, cool it to room temperature, transfer it to a 50mL volumetric flask, dilute to scale with water, and shake well. Pipette 5mL of this solution into a 50mL volumetric flask, add 10mL of thiourea (10%), and shake well. Add one drop of thymol blue indicator, neutralize with ammonia water (1+4) until it just turns yellow, add 5mL of buffer solution, shake well, accurately add 2.0mL of azopyrene III (0.05%) solution: dilute to scale with water, and shake well.
Blank solution: Take 5mL of water and add all reagents according to the analytical method. After color development, use the blank solution. Use 3cm colorimetric blood on the spectrophotometer at a wavelength of 650μm, and use the blank solution as a reference to measure the absorbance, and find the content on the standard curve.
A.5 Drawing of standard curve
In seven 50mL volumetric flasks, add 0.0mL, 0.5mL, 1.5mL, 2.0mL, 2.5mL, and 3.0mL of standard solution (0.01mg/mL) in sequence, and add 5mL of ascorbic acid. The following operations are carried out according to the analytical method. Measure the absorbance respectively and draw the standard curve. 6
