PREFACE
TheAssociationofHomeApplianceManufacturers(AHAM)developsstandardsinaccordancewithAHAM's"PolicyandProceduresGoverningTechnicalStandards"whichstates:
"AHAMStandardsshallbeinthebestinterest,mutually,ofconsumerswhouseappliances,theindustrieswhichprovideandserviceappliances,andotherinterestedparties.Theyshallrelatetoactualuseconditions,betechnicallyandscientificallysound."
UseorobservanceofAHAMstandardsisvoluntary.
AHAMstandardsarepresentedtotheAmericanNationalStandardsInstitute(ANSI)forrecognitionasAmericanNationalStandards.ThisstandardwassorecognizedonApril9,2002andbearstheAmericanNationalStandarddesignationANSI/AHAMAC-1-2002.
