Abstract
International and Korean standard test methods for evaluating the performance of electrical washing machines for household use were compare. Among various performance criteria, various test methods for evaluating fabric damage suffered by washing agitation during laundering were screened and their reliability and accuracy were compared. In addition, the effect of washing conditions on the fabric damage during laundering was also evaluated. As a result, it was revealed that it is necessary to establish additional standard test methods for evaluating fabric damage, entanglement of washing load, and mechanical detergent loss in the sump of sump of washing machines in Korean industrial standard. Among various test methods for evaluating fabric damage suffered by washing agitation, the test reliability of ISO, and modified IEC methods are better than that of EMPA and AHAM methods. Fabric damage increased severely as washing time, washing load, and the number of rinsing and extraction cycles increased.
