引用第9楼baifenbai于2010-06-20 11:36发表的:
美国能源之星关于EPS的要求中明确说了是送检三个样品,每个样品必须符合能源之星的要求,但是能源认证的清单上只列三个样品的平均值。详细请看下面的原文。
Number of Units Required for Test: Testing shall be conducted by the manufacturer or its? authorized representative on three randomly chosen units of the same model. Manufacturers shall? measure and maintain the Active Mode, No-Load Mode, and power factor values (if applicable) for all three units as well as the average values. To qualify as ENERGY STAR, all three units must meet the ENERGY STAR specification; only the average values will be displayed on ENERGY STAR’s qualifying product list (see Section 4.E below).
学习了 ,谢谢
