1、Designation:D3715/D3715M98(Reapproved 2011)Standard Practice forQuality Assurance of Pressure-Sensitive Tapes1This standard is issued under the fixed designation D3715/D3715M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year o
2、f last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1 This practice contains uniform quality a
3、ssurance provi-sions for pressure-sensitive tapes and establishes samplingplans and procedures for acceptance inspection.1.2 Limitations:1.2.1 This practice only includes procedures for when anupper or a lower specification limit is given.It does not providefor double,both minimum and maximum,specif
4、ication limits.NOTE1When double specification limits are given(applies tovariables testing only),use may be made of Table C-3 and Example C-3of ANSI/ASQC Z1.9.1.2.2 The variables sampling plans apply to a single qualitycharacteristic.Having obtained the sample and the responses tothe physical proper
5、ty tests,acceptance is determined on onequality characteristic at a time.The process is repeated for eachadditional characteristic.1.2.3 The variables sampling plans require that the responseto each quality characteristic is normally distributed eitherdirectly or by transformation.If this is not kno

7、equivalents;therefore,each systemmust be used independently,without combining values in anyway.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health pract
