章节6里面A simplified test method is permitted for equipment that undergoes minor changes or updates,

below 60 % of the applicable limits and the THD of the supply current is less than 15 %. The

Clauses 6 and 7 takes precedence over this simplified method.这里是指测试产品之前经过完整的测试，假如对产品进行了细微的升级。, \! N4 g. D( L. ^) t( T
我之前完成测试时满足谐波低于60%，THD低于15%。+ m5 @' j" A$ k$ k4 k( A1 t
那么我升级之后的产品如果功率在原来的±20%之间，THD测试值仍低于15%。我就认为是符合要求的？
