3 Terms and Definitions

Terms and definitions GB/T 18510 apply to this document defined. For ease of use, repeat the following list of GB/T 18510 in Certain terms and definitions. 3.1 Accuracy accuracy The test results are consistent with a degree of the true value of measuring true or conventions. Note. When accuracy is used for a set of results, a description of the effect of random errors and a common systematic error or bias. [GB/T 18510-2001, Definition 3.1] 3.2 Precision precision Under specified conditions, the degree of mutual agreement between independent test results. Note 1. The precision depends only on the random error, and has nothing to do with the value of true value is measured or other agreement. Note 2. The precision of measurement is usually "imprecision" means, as the test result and standard deviation is calculated. A large standard deviation reflects a higher fine is not density. Note 3. "Independent test results" means results are not affected before on the same or similar material obtained results. [GB/T 18510-2001, the definition 3.3] 3.3 Accuracy trueness The average degree of agreement with the measured true value or conventional true value of a large number of test results. Note. The accuracy of test results showing the size of systematic errors, bias is usually measured. [GB/T 18510-2001, the definition 3.4]
