3.2.2 The scale of the tester is 1ml in the range of 5 ~ 200ml. The capacity error of the scale at any position shall not be greater than aml.
Constant temperature bath
BQsy/7 56
The constant temperature bath shall be large enough and deep enough that water can overflow to a position greater than 85m of the scale after inserting two testers.
3.3.2 Support frame in the constant temperature bath. The volume should be able to be vertical and stable in it. When the temperature of the constant temperature bath is controlled at 54℃ and 82℃: it must be kept constant to 3.3.31
'3.4 Agitator,
3.4.1. The agitator consists of blades and connecting rods made of stainless steel. The blade is 120±1.5 long and 19±0.5 wide. Thickness is 15 guanidine. The connecting rod has a diameter of 6~7 m and is connected to the blade. See Figure 1.
Note---Sofo
Figure 1 Agitator
3.4.2 Under the rotation of 3500±15r/1n, the radial runout of the lower end of the agitator blade should be less than.
3.5 Thermometer
The thermometer is a mercury trousers thermometer with a scale value of 1℃ and an electrical insulation performance of
a sy/1 56t4
3.6.1 The leakage current of the electric heater shall not exceed 0.5mA. 3.6.2i
The insulation resistance of the tester housing shall not be less than 2mA. 3.6.3 The electric heater and the test seal shall be able to withstand a withstand voltage test of 500V with a frequency of 50Hz and a basic sinusoidal wave within 1m1n. There shall be no breakdown or flashover. 3.7 The test result of the tester shall be in accordance with the requirements of GB7306. 4 Test method
4.1 The dimensions of the tester parts shall be inspected with a measuring tool that can ensure the measurement accuracy and meet the requirements of 3.2, 3.4 and 3.6. 4.2 Constant temperature test
4.2.1 The calibration points of the constant temperature test are 54℃ and 82℃C. 42.2 The constant temperature bath medium is water or clear oil.
4.2.3 Adjust the constant temperature bath to the specified test temperature for constant temperature. 5 4℃ is 1 min.82c is 20min.
4.2.4 Immerse a second-class precision mercury thermometer in the constant temperature bath. Read once every 2min. Read five times in succession. The difference between the arithmetic mean of the readings and each reading value should not exceed 1℃: Then, change the position of the thermometer. Repeat the above sequence test. The result meets the requirements of 3.3.3.
4.3 On the special test device, vertically clamp the stirrer on the motor shaft of 500±15r/min and rotate it. Its radial runout should meet the requirements of 3.4.2. 4.4. The performance of electrical insulators shall be carried out in accordance with the provisions of JB2379: The results shall meet the requirements of 3.6. 4.5 The precision verification of the test results of the tester shall be carried out in accordance with G.B7305. 5 Inspection rules 5.1 Factory inspection Sz year e sy/ 674 5.1.1 All parts must be inspected and qualified. All purchased parts should have a certificate of conformity. And they must be re-inspected and qualified by the quality inspection department of the instrument manufacturer. 5.1.2 5.1.3 The tester must be inspected and qualified by the quality inspection department of the manufacturer before it can be shipped out of the factory, and a product certificate of conformity should be attached. 5.1.4 Inspection items shall be in accordance with 3.2~8.6. 5.2 Type inspection 5.2.1 Type test shall be carried out under one of the following conditions: & Trial determination and identification of new products or old products transferred to the factory for production; b. After formal production, if there are major changes in structure, materials, or processes. When it may affect the product performance:
c. When the cumulative production of the product reaches more than 2,000 units; &. When the product is discontinued for more than three years and then resumed, e. When the factory inspection results are significantly different from the last type inspection results. 1. When the national quality supervision and inspection agency proposes a requirement for type inspection. 5.2.2 Each type inspection shall not be less than 3 units. If all the inspection items of the sampled samples are qualified, the batch of products shall be qualified for type inspection. If there are unqualified items in the inspection results (the total number of items cannot exceed two, and the two items are limited to two different items of two products), samples twice the number of the first sampling number shall be drawn. If the re-inspection results are qualified. It is recommended to be qualified for type inspection. If there is still one item that is unqualified, the type inspection is unqualified.
