Abstract
Participating in the attempt by IEC (International Electrotechnical Commission) to establish the international standards of domestic washing machine which has been made since 1965, comparison tests were administered to see if the IEC cloths proposed for artificial soiling can be employed in the JIS method.
Three kinds of cloths (IEC, JIS-A and JIS-B) were artificially soiled in accordance with standard specifications and underwent washing tests by Tergotometer. The following results were obtained.
(1) General tendency of washability characteristics of the cloths from both origins is satisfactorily similar.
(2) Washability of the IEC cloths is higher than the JIS cloths.
(3) Range (R) of washability of the former is larger than the latter.
(4) The JIS standard cloth is more heavily soiled than the IEC cloth.
Effects of the size of test load on washability of the cloths were also investigated by JIS standard washing machine.
