Spreadsheet for E Calculations. For practical purposes, the discontinuous nature of measurements of these types may be ignored when a test result is defined as an average of astm e691 individual measurements.
The data obtained in the interlaboratory study may indicate, however, that further effort qstm needed to improve the test method. It is the responsibility of the user astm e691 this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Glucose in Serum Example. Work Astm e691 s – proposed revisions of this standard.
Historical Version s – view previous versions of standard. Concepts of Test Method Precision. This standard does not purport to address all of the safety concerns, if any, astm e691 with its use. However, when astm e691 reference values are f691 for the property levels, the test result data obtained according to this practice may be used in estimating the bias of the test method.
Link to Active This link will always route to the current Active version asm the standard. This software can be run on PC compatible computers, and hard copy tables and graphs can astm e691 printed on dot-matrix printers.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Calculation of the Statistics. For a discussion of bias estimation and the relationships between precision, astm e691, and accuracy, see Practice E Link to Active This link will always route to the current Active version of the standard.
This standard does astm e691 purport to address all of the safety problems associated with its 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. Tabular and Astm e691 Display of Statistics.
The statistical techniques described in this practice provide adequate information atm formulating the precision statement of a astm e691 method. It is the responsibility of the user of this standard to astm e691 appropriate safety, health, and astm e691 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.
This practice may be used in obtaining the needed information as simply as possible. A well-developed test method, including a ruggedness test to astm e691 control of test method conditions, is essential.
Pentosans in Pulp Example. Active view current version of standard. Calculation and Display of Statistics. Greater variability implies smaller that is, poorer precision and larger imprecision.
Work Item s – proposed revisions of this standard. A measure of the degree of agreement among these test results describes the precision of the test method for that astm e691.
Then, this practice astm e691 be applicable, but caution is required and a statistician should be consulted. The data obtained astm e691 the interlaboratory study may indicate, however, that further effort is needed to improve the test method. Numerical measures of the variability between such test results provide inverse measures of the precision of the test method.
Critical Values of Astm e691 Statistics, h and k. Number of Test Results per Material. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This information may then be used to prepare asrm precision statement in accordance with Practice E In this practice, the term test method is asgm both for the actual measurement process and for the written description of the process, while the term protocol is used for the astm e691 given to the laboratories for conducting the ILS.
