PREFACE

TheAssociationofHomeApplianceManufacturers（AHAM）developsstandardsinaccordancewithAHAM's"PolicyandProceduresGoverningTechnicalStandards"whichstates:

"AHAMStandardsshallbeinthebestinterest,mutually,ofconsumerswhouseappliances,theindustrieswhichprovideandserviceappliances,andotherinterestedparties.Theyshallrelatetoactualuseconditions,betechnicallyandscientificallysound."

UseorobservanceofAHAMstandardsisvoluntary.
