On the engineering side, the previous batch of 902 will be classified. The next batch of 902 will be confirmed again because there is already a part with a larger filter outer diameter. The original measurement method was that the needle was not parallel to the surface, and there were indeed differences in later testing. To avoid unnecessary errors, the engineering will use the needle to measure the surface parallel, and make another confirmation. In the future, it will not be 100% accurate to measure every 902&903, We will conduct spot checks to determine if the outer diameter is greater than 2.008 and 2.017, and we will ask IMS to evaluate whether to use it in the futureIf the remaining 902 is no longer accepted for testing, the engineering department will send it back to the workshop togethe
