Hello,
I am struggling finding answers to my concern with Tape Measures. I learned that if a Tape Measure is used to verify parts it needs to be calibrated. So far so good...
Now, on the other hand I learned that a Measurement system should be 10x more accurate than the print states.
For example: Print shows 1.125" ±0.030 or 1.315" ±0.060
Doesn't this mean the Measurement System should have an accuracy of x.xxxx?
Conventional Tape Measures do have an accuracy of 1/32 or less.
My uncertainty is that a Tape Measure is more likely a tool that gives you somewhat of an accuracy, it only gives you 1/32 intervals. I understand if a tolerance of 0.060 is applied it might work, but what if when a tolerance of 0.030 is applied (1/32 = 0.03125")?
I am curious to get answers that let vanish my uncertainty...
Thank you in advance for your help,
Thomas
