The tool will automatically check the average and individual-strength requirements.
Important: If an individual test result exceeds 125% of the specified class strength,
only 125% of the specified strength is used for calculating the conformity average. The actual test result
is not changed or rejected. The lot passes compressive strength only when both the adjusted average and
every individual result satisfy the applicable requirements.
