For QS 9000 Does the temp and humidity gages have to be controlled and calibrated? IP: Logged |

If you are performing calibrations your environmental insturments must be calibrated. The uncertainty of the environmental insturments is also a component of the combined measurement uncertainty and must be reported by whoever calibrates them. IP: Logged |

Also remember that if a product is brought into a controlled lab environment it must be held and stabilized. If a metal part is brought in from a production floor that is 95 degrees it should be held in the "controlled" environment to ensure that the normal expansion and contrtaction, due to temp change, is minimized. I'm not sure where they are, but there are tables that can convert temperature expansion/contraction rates to reduce the "hold time" required for proper inspection. Help from the Lab people please!

quote: I assume the temperature and humidity gages are used to monitor those parameters in an area where work is done. To repeat the question often asked by Phil Stein, "Does it matter if those measurements are wrong?" In other words, do variations in temperature and humidity affect the quality of the work being done there? If the answer is "Yes", then calibrate the instruments. If the answer is "No", then why are you making the measurements at all? Note that this principle applies generally to all test and measuring instruments ... ------------------ IP: Logged |
