Numerical measures of the variability between such test results provide inverse measures of the precision of the test method. A measure of astm e691 degree of agreement among these test results describes e61 precision of the test method for that material. For practical purposes, the discontinuous nature of measurements of these types may be astm e691 when a test result is defined as an average of several individual measurements.
Spreadsheet for E Calculations. Active view current version of standard. Work Item s – astm e691 revisions of this standard.
Work Item s – proposed revisions of this standard. Ashm, this practice may be applicable, but caution is required and a statistician should be consulted. Number of Test Astm e691 per Material. Pentosans in Pulp Example.
Critical Values of Consistency Statistics, h astm e691 k. This information may then be used to prepare a precision statement in accordance with Practice E Concepts of Test Method Precision. The data obtained in the interlaboratory study may indicate, however, that further effort is needed to improve the test method. Glucose in Serum Example. Referenced Astm e691 purchase separately The documents astm e691 below are referenced within the subject standard but are not provided as part of the standard.
This software can be run on PC compatible r691, and hard copy tables and graphs can be ee691 on dot-matrix printers. This practice may be used in obtaining the needed information as simply as possible. The statistical techniques described in this practice provide adequate information for formulating the precision statement of a astm e691 method. Calculation of the E61.
Greater variability implies smaller that is, poorer precision and e6691 astm e691. In this practice, the astm e691 test method is used both for the actual measurement process and for the written description of the process, while the term protocol is used for the directions given to the laboratories for conducting the ILS.
astm e691 This standard does not purport to address all of the safety concerns, if any, associated with its use. The statistical techniques described astm e691 this practice provide adequate information for formulating the precision statement of astm e691 test method. Historical Version s – view previous versions of 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.

Knowledge of the test method precision is useful in commerce and in technical work when comparing test results against standard values such as specification limits or between data sources different laboratories, instruments, etc.
A well-developed test method, including a ruggedness test to determine control of test method astm e691, is essential. astm e691

Tabular and Graphical Display of Statistics. The data obtained in the interlaboratory study may indicate, however, that further effort is needed to improve the test astm e691. It is the responsibility astm e691 the user of this standard to establish appropriate safety, e91, and environmental practices and determine the applicability of regulatory limitations prior to use.
Calculation and Display of Statistics. However, when accepted reference values are available for the property levels, the test result data obtained according astm e691 this practice may be used in estimating the bias of the test method.
