Overview
What is Bitumen Extraction Apparatus Calibration?
Binder content by centrifuge extraction (ASTM D2172) depends on the extractor reaching sufficient speed to wash all binder from the aggregate — an under-speed bowl leaves binder behind and under-reports bitumen content, corrupting the very JMF verification the test exists for.
Global Lab verifies true bowl speed with NPLI-traceable non-contact tachometers across the control range, inspects bowl seating, gasket condition and drainage, verifies timer function, and certifies the apparatus against the method's requirements with as-found data.

Test Procedure
How the Bitumen Extraction Apparatus Calibration is Conducted
- 1
Assembly Inspection
Bowl seating, gasket, filter-ring lands and drainage condition are inspected. - 2
Speed Measurement
True bowl speed is measured with a traceable non-contact tachometer across the control range. - 3
Timer Verification
Cycle timers (where fitted) are checked against reference chronometers. - 4
Evaluation
Results are evaluated against method apparatus requirements. - 5
Certification
As-found speed table and verdict are issued via Autovity QLMS.
