Introduction to ASTM test method - Explanation of Terms
Introduction to ASTM test method - Explanation of TermsAccuracy - The accuracy of a test is a measure of how close the test result will be to the true value of the property being measured. As such the accuracy can be expressed as the bias between the test result and the true value. However, the absolute ...
