Tapes come with certified calibration documentation certifying that standards and equipment used for inspection are certified accurate with reference to 68 degrees F, traceable to Master Standards at the National Institute of Standards and Technology (NIST). Calibration is performed with transfer standards which are progressively more accurate in the order of 4: 1. Starrett attests that the measuring and test equipment and calibrations performed on the tapes are in accordance with ISO 17025:2017, ANSI/NCSL Z540-1, Mil-STD- 45662A. Accuracy- when the tape is supported on a horizontal surface and pulled with tension of 10 pounds at a temperature of 68 degrees Fahrenheit, the over-all length will not be in error by more than .50″ in 50′.
A note on calibration dates:
Calibration dates are suggested by the manufacturer. You may overwrite the one year re-calibration date with an interval of your choosing, as long as this is documented in your Quality Manual or other quality documents. Atema recommends a 5 year re-calibration date for gages used as a Master set.
