Ministry of Electronics Industry of PRC Table of Contents1 Subject content and scope of application... 3 2 Method summary... 3 3 Apparatus and reagents... 3 4 Test steps... 4 5 Result calculation... 4 6 Test report... 5 Additional information... 7 Determination of area-resistance of separator1 Subject content and scope of applicationThis Standard specifies the measurement method for the area-resistance of alkaline battery separators. This Standard applies to the determination of area-resistance of alkaline battery separators such as hydrated cellulose film, polyethylene radiation grafted film, nylon felt, nylon cloth, vinylon non-woven fabric, hydrated cellulose paper, asbestos paper, and cotton paper.2 Method summaryRespectively measure the resistance value of the separator of a specified area immersed in a potassium hydroxide solution of a specified concentration AND the resistance value of a potassium hydroxide solution of the same concentration and area. The product of the difference between the two and the test area of the separator is the resistance of the separator, expressed in Ω·cm2.3 Apparatus and reagents3.1 Resistance measuring apparatus 3.1.1 The measurement frequency is 1 kHz. 3.1.4 Normal operating conditions of the apparatus 3.2 Resistance test slot (as shown in Figure 1). 3.3 Plug-in board with a hole whose area is 10 cm2. 3.4 Potassium hydroxide solution, analytical reagent, 40% (or as required by the detailed product specification). 3.5 Constant temperature bath. 23 ± 2 ℃.4 Test steps4.1 Cut the sample into 5 pieces of 40 mm × 60 mm. 4.2 Place the test sample in a 40% potassium hydroxide solution at 23 ± 2 ℃ and soak for 4 hours. 4.3 Pour potassium hydroxide solution into the resistance test slot according to 4.2 and continue to maintain constant temperature. 4.6 Clamp the sample in the plug-in board; insert it into the resistance test slot; measure the total resistance R2 of the sample and solution.5 Result calculation5.1 Calculate the resistance R of separator as follows. 5.2 Take the arithmetic mean of the 5 measurements as the test result. 5.3 Calculate the standard deviation. 5.4 Round off the resistance of separator to about 0.01 Ω·cm2.6 Test reportThe test report shall contain the following contents.
