Additionally, our laboratory is security controlled. Parts are handled by laboratory trained personnel only, and are stored discreetly out of view of the public and/or visitors. Our lab is maintained by security code entry guaranteeing each inspection performed by Bobier Metrology is confidential.
So, if you send parts out for independent certification be sure and review the laboratory scope and specifications. Pay close attention to the uncertainty of measurement and temperature used in the calculations.
If a certification becomes just an opinion, then the courts will decide who is right and who is wrong. If this happens to your products, the money spent to clarify an opinion will pale when compared to the higher inspection costs (charges) of a 68°F laboratory.
The only way to achieve repeatability and accuracy over time is to control the temperature in the measurement environment.
