1、Designation: F 494 05An American National StandardStandard Test Methods forEvaluating Primary Disposable Bag Integrity for VacuumCleaners1This standard is issued under the fixed designation F 494; the number immediately following the designation indicates the year oforiginal adoption or, in the case
2、 of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 These test methods cover the evaluation of the integrityof the primary disposable bag used
3、for vacuum cleaners.1.2 The intent of these test methods is to verify that thedesign of the primary disposable bag will perform satisfactorilyfor the consumer in a wide range of normal use conditions. Thefiltering capability of the disposable bag is not evaluated withthe use of these test methods.1.
4、3 The following tests are included:SectionInstallation and Removal 3Workmanship 4Durability 5Seams and Joints 61.4 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.1.5 This standard does not purport to address all of the
5、safety problems, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Significance and Use2.1 These test methods are useful for routine co
6、ntrol, designof end-use products, and acceptance testing for conformance tospecifications. Good workmanship, seams, and joints thatremain strong over a wide range of atmospheric conditions andhave the ability to withstand repeated cycles are necessary forsatisfactory end use to the consumer.TEST MET

15、 exposed to circulating air andconditioning relative humidity and temperature within thelimits specified in 5.5.5.2.3 Temperature-Measuring Equipment, accurate towithin 61F (60.5C).5.2.4 Humidity-Measuring Equipment, accurate to within62 % relative humidity.5.2.5 Solenoid, to control the movement of
16、 a spring-loadedplate.5.2.6 Timer, to control the activation of the solenoid on thebasis of time.5.2.7 Plate, to seal the intake of the test cleaner. This plate,connected directly to the solenoid shaft, must open sufficientlyso as not to restrict air flow and must open and close the intakewithin 0.1
