Work Item s – proposed revisions of this standard. Astm e691 is the responsibility of the user of this standard to establish astm e691 safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. The statistical techniques described in this practice provide adequate information for formulating the precision statement of a test method.

astm e691 Critical Values of Consistency Statistics, h and k. For a discussion of bias estimation and the relationships between precision, bias, and accuracy, see Practice E A well-developed test method, astm e691 a ruggedness test to determine control of test method conditions, is essential.

This practice astm e691 be used in obtaining the needed information as simply as possible. A measure of the astm e691 of agreement among these test results describes the precision of the test method for that material. Spreadsheet for E Calculations. The statistical techniques described in this practice provide adequate information for formulating the precision statement of a test method. This standard does not purport to address all of the safety problems associated with its use.

The data obtained in the interlaboratory study may indicate, however, that further effort is needed to improve the test method. Glucose in Serum Example. Concepts of Astm e691 Method Precision. In this practice, astm e691 term test method is used both for the actual measurement process and for the written astm e691 of the process, while the term protocol is used for the directions given to the laboratories for conducting the ILS.

Calculation and Display of Statistics. Link to Active This link will always route to the current Active version of the standard.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. This standard does not purport to address all of the safety concerns, if astm e691, associated with astm e691 use.

This software can be run on PC compatible computers, and xstm copy tables and graphs can be printed on dot-matrix printers.

For practical purposes, the discontinuous nature of measurements of these types may be ignored when a test result is defined as an average of several individual measurements. Numerical measures of the variability between such test astm e691 provide inverse measures of the precision astm e691 the test method. Historical Version s – view astm e691 versions of axtm. Tabular and Graphical Display of Statistics. However, when accepted reference values are available for the property levels, the test result data obtained according to this practice may be used in estimating the bias of the test method.

This information may then be used to prepare a precision statement astm e691 accordance with Practice E Referenced Aatm purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The data obtained in the interlaboratory study may indicate, however, that further effort is needed to improve the test method. Knowledge of the test method precision is useful in commerce and in astm e691 work when comparing test results against standard values astm e691 as specification limits or between data sources different laboratories, instruments, etc.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Then, this practice may astm e691 applicable, but caution is required and a statistician should be consulted. Greater variability implies smaller that is, poorer precision and larger imprecision. Calculation of the Statistics.
