Active Standard: E1050 - 12
In order to verify the precision and bias statement in the standard is correct, this work item will commission a round robin coordinated with ASTM C522 testing to establish the current repeatability and reproducibility for ASTM E1050 with multiple materials. It has been many years since a round robin was held for ASTM E1050.
