Height Blocks – ISO 17025-Certified Calibration

Calibrate and verify height on your Pine 125X, G1, and G2 Superpave Gyratory Compactors using Pine Height Blocks.  Pine offers height blocks for purchase with a certificate of calibration as well as recalibration services.

Re-Certification Interval

AASHTO R18 does not specify the re-certification interval for measurement standards.  Therefore, AASHTO follows the recommendation of the manufacturer, which is 24 months for Pine Height Blocks.

ISO 17025-Certified Calibration

AASHTO R18-17 Section 6.2.1.5 requires measurement standards, which includes Pine Height Blocks, calibrated on or after January 1, 2018 to be calibrated by a laboratory that is ISO 17025-certified to calibrate the dimensions of the Height Blocks.  Purchase AASHTO R18 from the AASHTO Bookstore.
