When testing stainless steel locking weights, one step is to verify the magnetic susceptibility of the weights, but many people are not very familiar with the method of verifying the magnetic susceptibility of the weights. Let's follow the small editor to have a look!



Everyone knows what the validation items for standard weights include. The roughness of the weight surface, the accuracy of the weight and the magnetic susceptibility of the weight will be discussed today. From this, it can be seen that the error of the standard weight grade can be verified by the metrological institution. As is well known, weight verification requires a stable environmental foundation. Therefore, we need to place the weights in the measuring instrument before inspection to reduce the temperature difference between the weights and the measuring instrument. In addition to verifying the stability of the environment, the temperature in the laboratory also needs to be stable! During the calibration process, the higher the weight level, the higher the requirement for temperature change, and different levels have different specifications and temperature change ranges. So, for weights of class F and above, we not only need to pay attention to temperature stability, but also to humidity. The humidity in the laboratory needs a standard range and cannot exceed this range. What is the price of stainless steel weights? Come and call me!

Therefore, when we test the magnetic susceptibility of the weight, we should first place the weight vertically on the operating platform, and then measure the weight: height, radius, top to magnet center and bottom to magnet center. Then we need to clearly know what the gravitational acceleration is, and the accuracy should reach 1%. Next, rotate the north pole of the magnet downwards and measure the magnetic moment. We will reset the instrument to zero again. The magnet should be in the upper position, and then the weight should be placed again on the experimental platform. The weight should be placed in the center of the experimental platform, and the measured values should be recorded truthfully. Finally, we can calculate the magnetic susceptibility of the weight.



The relevant regulations clearly stipulate that if the magnetic susceptibility of weights of different specifications is less than the specified limit value, the uncertainty caused by this situation can be ignored, otherwise the accuracy of the weights will be affected.
