The Pine GB1 Brovold Calibration Kit includes a force calibration kit, a height tube, and block for measuring external angle of gyration.
Pine recommends an initial 12-month calibration interval and 24 months thereafter for the Force Calibration Kit and a 24-month calibration interval for the Height Tube. Because AASHTO R18 does not specify the re-certification interval for measurement standards, AASHTO adopts the recommendation of the manufacturer.
ISO 17025-Certified Calibration
AASHTO R18-17 Section 188.8.131.52 requires a Pine force calibration kit calibrated on or after April 13, 2017 to be calibrated by a laboratory that is ISO 17025-certified to calibrate it according to ASTM E74. The same AASHTO standard section requires Pine Height Tubes calibrated on or after January 1, 2018 to be calibrated by a laboratory that is ISO 17025-certified to calibrate it. Purchase AASHTO R18 from the AASHTO Bookstore. Acquire ASTM E74 from ASTM International.
