Hi everybody
while defining the calibration and verification under 7.6 Control of monitoring and measuring equipment.
I have the following equipment:
1 caliper 150 mm named A
1 steel rule "Moore & Wright ER424" with 0.5 mm resolution
1 caliper 150 mm named B
1 micrometer.
In order to comply to standard, I sent all the equipment to an external supplier for the calibration and I have the certificates.
I have a print shop business, in fact we dont need tight tolerances
I accept +/- 1 mm in my product, in the past I have not had quality problems due to bad measurements.
Normally I use for inspection of the product the steel rule
The micrometer is used to measure sheets of paper and caliper is used to measure some ancillary equipment.
At this time I comply with calibration, but not for verification, for that, I have an idea.
The caliper A is a spare caliper, in case of failure of caliper B, the A is kept in a secure place and only will be used in such case.
Verification are planned every 6 months.
Question
Could I use the caliper A to verify caliper B, say measuring one part and comparing results, if such results fall within +/-1 mm, my caliper B is ok?
The same task it can be done with the micrometer, compared against caliper B, I dont want to spend money in gage blocks.
For the steel rule, I will only do visual inspection, (legible marks, numbers, etc.).
Other option it is not to verify the equipment and wait every year for the calibration of them, since our place is clean, measuring equipment is not
too much used, personnel take care of them, additionally my tolerances are not too tight.
Please shed light on me, give me some input
Thanks
