Washing Machines
Under the existing grading standard, horizontal axis and vertical axis washing machines which obtain Grade 1 under the existing grading standard are about 38% and 24% more efficient than those under the past standard respectively. Grade 1 of the past standard is reclassified into Grade 1 to Grade5.

Comparison of the past and existing grading standards of vertical axis washing machines
Lower specified energy consumption (Esp) indicates a washing machine with higher energy efficiency.
