1、Designation:D660000(Reapproved 2013)Standard Practice forEvaluating Test Sensitivity for Rubber Test Methods1This standard is issued under the fixed designation D6600;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last r

3、nded and cured rubbers,which mayfrequently be conducted by one or more test methods.Whenmore than one test method is available,two questions arise:Which test method has the better(or best)response to ordiscrimination for the underlying fundamental property beingevaluated?and Which test method has th

4、e least error?Thesetwo characteristics collectively determine one type of technicalmerit of test methods that may be designated as test sensitivity.1.2 Although a comprehensive and detailed treatment,asgiven by this practice,is required for a full appreciation of testsensitivity,a simplified concept

5、ual definition may be givenhere.Test sensitivity is the ratio of discrimination power for thefundamental property evaluated to the measurement error oruncertainty,expressed as a standard deviation.The greater thediscriminating power and the lower the test error,the better isthe test sensitivity.Borr

6、owing from the terminology inelectronics,this ratio has frequently been called the signal-to-noise ratio;the signal corresponding to the discriminationpower and the noise corresponding to the test measurementerror.Therefore,this practice describes how test sensitivity,generically defined as the sign

7、al-to-noise ratio,may be evalu-ated for test methods used in the rubber manufacturingindustry,which measure typical physical and chemicalproperties,with exceptions as noted in 1.3.1.3 This practice does not address the topic of sensitivity forthreshold limits or minimum detection limits(MDL)in sucha
