We have already produced glass on the basis of Rev.2 drawing.
But they don't satisfy Rev.2, so we ask you to change tolerance to ±0.10.
Average of weight is 1.10 mg.
Max. is 1.18 mg , Min. 1.05 mg.
Rev.2 1.10±0.05 mg (1.05-1.15 mg)
Could you please accept the above glass?
In case your hope (1.15-1.3) is adopted, the weight is 1.20 +0.1 /-0.05 mg.
It is too difficult to satisfy the requirement in the range of 0.15 mg.
