四、        准备工作IV Preparatory work  

 1. 镉电极 Cadmium electrode

 ①  清洗镉电极Clean cadmium electrode

在制作镉电极时，其表面形成了一层保护膜，为获得最佳导电性能，需要将镉电极表面的保护膜清除，使用前从耐酸容器中取出，应用乙醇浸泡1-2小时，取出后用动物毛刷及纯水冲洗干净。

When making cadmium electrode, a protective film is formed on its surface. In order to obtain the best conductivity, it is necessary to remove the protective film on the surface of cadmium electrode. Before use, take it out of the acid resistant container, soak it in ethanol for 1-2 hours, and then rinse it with animal brush and pure water.

②浸泡镉电极Immersed cadmium electrode

将清洗后的镉电极浸泡在比重(密度)ρ为1.10g/cm³的稀硫酸溶液中3昼夜以上，否则因极化作用面量值不准，应注意以后当不用镉电极时必须把它浸在稀硫酸溶液中，以防止其表面干燥。

Soak the cleaned cadmium electrode in specific gravity (density) ρ 1.10g/cm ³ In the dilute sulfuric acid solution for more than 3 days and nights, otherwise, due to the inaccurate value of the polarization surface, it should be noted that when the cadmium electrode is not used in the future, it must be immersed in the dilute sulfuric acid solution to prevent its surface from drying.

2、 硫酸分析纯及试样

①  硫酸(分析纯)

用液体比重计调试密度为1.28±0.005g/cm³硫酸溶液（25℃时）。

Sulfuric acid (analytical purity)

Use a hydrometer to adjust the density to 1.28 ± 0.005g/cm ³ Sulfuric acid solution (at 25 ℃).

②  试样的制备

将样品裁成142mm×146mm的试样，若样品尺寸小于上述尺寸，则至少裁成125mm×135mm（可按测试槽内面积裁最大尺寸）的试样，每组试样的片数不得少于表-1规定。将裁好的试样放入耐酸容器内使试样完全浸没在25±2℃，密度为1.28±0.005g/cm³硫酸溶液中，浸酸时间为1–5h(小时0，以试样浸透为限，启动干式荷电蓄电池用隔板浸泡为20 min，毡型隔板不用浸酸。

Preparation of samples

Cut the sample to 142mm × 146mm sample. If the sample size is smaller than the above size, it shall be cut to at least 125mm × For 135mm (the maximum size can be cut according to the area in the test tank), the number of pieces of each group of samples shall not be less than that specified in TABLE-1. Put the cut sample into an acid resistant container so that the sample is completely immersed in 25 ± 2 ℃, and the density is 1.28 ± 0.005g/cm ³ In the sulfuric acid solution, the soaking time is 1-5h (0 hours), which is limited to the soaking of the sample. The diaphragm for starting the dry-type charged battery is soaked for 20 minutes, and the felt diaphragm does not need to be soaked in acid.

五、        操作operation

①          将分析纯硫酸缓缓倒入测试槽内，调整测试槽内的硫酸溶液的温度为25±2℃；调整硫酸溶液密度为1.28±0.005g/cm³;调整测试槽内硫酸液面高度比试样被侧面上边高5mm。

    Slowly pour the analytical pure sulfuric acid into the test tank, and adjust the temperature of the sulfuric acid solution in the test tank to 25 ± 2 ℃; Adjust the density of sulfuric acid solution to 1.28 ± 0.005g/cm ³; Adjust the height of sulfuric acid level in the test tank to be 5mm higher than the upper side of the sample.

②          关闭测试仪所有开关按 (向下位置)，将电源插头插入电源插座，从左到右顺序打开所有开关，旋动“调节电流”旋钮使电流表的读数为1-2A，对测试槽进行充电，直到电压表的读数稳定（第一次充电时间较长）

Turn off all switches of the tester, press (down position), insert the power plug into the power socket, turn on all switches from left to right, turn the "adjust current" knob to make the reading of the ammeter be 1-2a, and charge the test tank until the reading of the voltmeter is stable (the first charging time is long)

③          旋动“调节电流”按钮，使电流表读数为1.00A，待电流表读数稳定后记录电压表的读数“V0”，然后根据表-1规定，从耐酸容器中取出试样插入测试槽中间空格中（毡型隔板直接插入），若试样间存在间隙应用夹具紧试样，待电压表读数稳定后记录电压“V1”。

    Turn the "adjust current" button to make the reading of the ammeter be 1.00a. After the reading of the ammeter is stable, record the reading of the voltmeter "V0". Then, according to the provisions of TABLE-1, take the sample out of the acid resistant container and insert it into the middle space of the test tank (the felt diaphragm is directly inserted). If there is a gap between the samples, clamp the sample tightly, and record the voltage "V1" after the reading of the voltmeter is stable.

④  根据电压测定法公式计算Calculated according to the formula of voltage measurement method

R= (V1-V0)× S (m×I)

式中Where

R: 试样电阻   Ω

  Sample resistance    

V0: 插入试样前电压表读数

Voltmeter reading before sample insertion

V1：插入试样后电压表读数

   Voltmeter reading after sample insertion      

S:  试样有效测试面积 cm

   Effective test area of sample cm

I:  电流1A    Current 1A   

m： 插入试样的片数Number of inserted samples

注：若起动用干式荷电蓄电池用隔板浸泡20min测定不合格，而浸泡20min以上电阻测定合格，则该隔板适用于非干式荷电蓄电池。

Note: if the diaphragm used for starting dry-type charged battery is not qualified after soaking for 20min, and the resistance is qualified after soaking for more than 20min, the diaphragm is applicable to non dry-type charged battery.
