ASTM WK33655

    Work Item: ASTM WK33655 - New Practice for Determining the Effect of Sample Conditioning on Test Results

    (What is a Work Item?)

    Developed by Subcommittee: D04.94 | Committee D04 | Contact Staff Manager



    1. Scope

    1.1 Sample conditioning changes the measured response during testing. The purpose of this practice is to provide a method to determine the effects of conditioning and nonconditioning of samples before testing and determine if the length of conditioning influences the test result. This practice makes use of the paired-t test and measured precision and bias to determine statistical differences between data populations. 1.2 Units--The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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 practice will be used by researchers, government agencies, and in quality control testing to determine the effect of sample conditioning.
