The quality control room is currently temperature controlled & I'm looking to a Temp & Humidity Data Logger (as mentioned by Kirley) Forgive my lack of knowledge as I'm new to the machining/manufacturing world.ġ & 3) The company decided to do in-house "calibration" last year on shop and personal mics, calipers, indicators, height gages against a master block set. The question, more so, is if I'd be on the correct path to interpreting and initially executing the requirement with minimal adjustments needing to be made. Including, I'm going to avoid any verbiage that insinuates 'declaring' ISO and/or ANSI conformance. I hope this makes Thank you both! I definitely believe that I'm dumb and did not understand what the words 'calibrate' and 'verification' actually meant. These individual numbers should be recorded so you can show the previously failed block was not used for the present day calibration. What did you receive when purchasing the master set? I don't see individual serial numbers on precision pins, but I see them on better quality gauge blocks. It gets replaced, then what you have is a new piece in the old master set. With these types of records I find individually recording the temperature and humidity on individual certificates to be a complete waste of time.Ībout master sets: I have too often seen a master set's calibration report with one piece failing. I have seen the reports they generate when plugged in with USB they are impressive and can be retained as records. Some are disposable (last about a year), while others have batteries that can be replaced. Some can be set up to send an alarm if conditions fall outside of defined parameters. Many types of temperature and humidity data loggers are available, which chart the readings so a person can trace the conditions on a given day and time. I do not remember seeing temperature and humidity recordings on any of the calibrations. These are the data points I have seen on oh-so-many calibration certificates.
If an instrument needs adjustment the as-left result is recorded as well. As found results are recorded, over the instrument's range depending on the instrument (a scale, for example).
I don't have a copy of the AS standard in front of me, nor ANSI Z540-3 or ANSI B89.6.2 but I am familiar with the environmental controls called out in 17025.Ĭalibration takes place using traceable standards, performed by qualified individuals in a controlled environment, in accordance with established procedures.
