章节6里面A simplified test method is permitted for equipment that undergoes minor changes or updates,
" I' q0 K# D) B0 |provided that, in previous full compliance tests, it has been shown to have current emissions

$ k% B* I9 R! o5 f$ I4 l- M  wsimplified test method consists of verifying that the updated equipment has an active input
power within ±20 % of that of the originally tested product, and that the THD of the supply
current is less than 15 %. Products that fulfill these requirements are deemed to comply with

( D; O/ v0 p2 Y$ o. r  |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。
我之前完成测试时满足谐波低于60%，THD低于15%。
( {! ?* I( u8 D: o! K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？
