Link to Active This link will always route to the current Active version astm e691 the standard. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Then, this practice may be applicable, but caution is required and a statistician should be consulted. Numerical measures astm e691 the variability between such test results provide inverse measures of the precision astm e691 the test method.
Active view current astm e691 of standard. However, astm e691 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. Greater variability implies smaller that is, poorer precision and larger imprecision.
Critical Values of Consistency Statistics, h and k. Work Item s – proposed revisions of this standard. astm e691
The statistical techniques described in this practice provide adequate information for formulating the astm e691 statement of a test method. In this practice, the term test method is used both for the actual measurement process astm e691 for the written description of the process, while the term protocol is used for the directions given to the laboratories for conducting the ILS.
For a discussion of bias estimation and the 6e91 between precision, bias, and accuracy, see Practice E The data obtained in astm e691 interlaboratory study may indicate, however, that further effort is needed to improve the test method. This standard does not purport to address all of the astm e691 concerns, if any, associated with its use. This software can be run on PC compatible computers, and hard copy tables and graphs can be printed on dot-matrix printers.
This information may then be used to prepare a precision statement in accordance with Practice E Astm e691 Documents purchase separately The documents listed below are referenced within the subject standard but astm e691 not provided as part of the standard. Link to Active This link will always route to the current Active version of the standard.
Calculation and Display of Statistics. Tabular and Graphical Display of Statistics. Spreadsheet for E Calculations. Astm e691 statistical techniques described in aatm practice provide adequate information for formulating the precision statement of a test method.
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. Number of Test Results per Material. Historical Version s – view previous versions of standard. Astm e691 standard does not purport to address all of the safety problems associated with its use. The data obtained in the ashm study may indicate, however, that further effort is needed to improve the test method.
A measure asgm the astm e691 of agreement among these test results describes the precision of the test method for that material.
For practical purposes, the discontinuous nature of measurements of these types astm e691 be ignored when a test result is defined as an average of several individual measurements. Glucose in Serum Example.
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, astm e691, etc.
Astm e691 of the Statistics. A well-developed test method, including a ruggedness test to determine control of test method conditions, is essential. asmt
Work Item s – proposed revisions of this standard. Concepts of Test Method Precision.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This practice may be used astm e691 obtaining the needed information as simply as possible. Pentosans in Pulp Example.
