1、Designation:F49405(Reapproved 2011)An American National StandardStandard Test Methods forEvaluating Primary Disposable Bag Integrity for VacuumCleaners1This standard is issued under the fixed designation F494;the number immediately following the designation indicates the year of originaladoption or,
2、in the case of revision,the year of last revision.Anumber in parentheses indicates the year of last reapproval.Asuperscriptepsilon()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 use
3、d 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 Removal3Workmanship4Durability5Seams and Joints61.4 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 thesafe
5、ty 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 control,de
6、signof 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 METHODS3.Install
7、ation and Removal3.1 ScopeThese test methods provide guidelines for theinstallation and removal of the primary disposable bag.3.2 ApparatusThe vacuum cleaner model for which theprimary disposable bag is intended.3.3 Test Specimens Test specimens shall be representativeof the primary disposable bag s
8、ystem being tested.3.4 ProcedureThe primary disposable bag shall be in-stalled in accordance with the instructions of the vacuumcleaner manufacturer.3.4.1 Construction of the primary disposable bag shall besuch that no holes or tears will be made when it is prepared forinstallation.3.4.2 When instal
9、led or removed,in accordance withinstructions,the primary disposable bag shall not be damagedor its function impaired.3.5 ReportThe report shall include any problems encoun-tered during installation and removal of the primary disposablebag.4.Workmanship4.1 ScopeThis test method provides a means of e
10、valuatingworkmanship of the primary disposable bag.4.2 Test Specimens Test specimens shall be representativeof the primary disposable bag system being tested.4.3 ProcedureInspect primary disposable bag for confor-mance to the following:4.3.1 Complete sealing or fastening of all seams,tucks,joints,an
11、d attachments,4.3.2 No tears,rips,holes,or other manufacturing typefaults,4.3.3 Printed instructions,when they appear,shall be clearand legible,4.3.4 Dimensions shall agree with drawing specifications,orthe primary disposable bag as defined by the vacuum cleanermanufacturer,and4.3.5 If adhesives are
12、 used for seams and joints,there shallbe no bleed through to adjacent plys or misplacements.4.4 ReportThe report shall include any defects in work-manship noted in the inspection in 4.3.1These test methods are under the jurisdiction of ASTM Committee F11 onVacuum Cleaners and are the direct responsi

14、ed States1 5.Durability5.1 ScopeThe durability of the primary disposable bag isdetermined by a life test within the vacuum cleaner for whichthe bag is intended.5.2 Apparatus:5.2.1 Vacuum Cleaner.5.2.2 Conditioning Chamber or Cabinet,in which speci-mens may individually be exposed to circulating air
15、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 a spring-loadedplate.5.2.6 Timer,
16、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 s.Motion of the plate must not be a sliding action.5.2.7.1 Canister CleanersThe plate seals the nozzle endof the hose normally supplied with the vacuum cleaner.Thehose is attached to the vacuum cleaner in the normal mannerwith no attempt
