I am not sure if you are discussing UL962 Standard,which is effective only in recent years.If you have any evidence about violating the standard,you can provide it to UL China for appeal.I also can assist you.

Standard is: UL 1310
Product is: linear transformer/adaptors
Our competitor applied UL certificate through Taiwan UL, its test report is much simple than Hong Kong UL, and shows no construction. Its end product exceeded the standard allowed temperature rise.
My questions are:
1. Is it good to apply through China UL?
2. What action China UL would take, if we provide samples which violated the standard?

sure,different engineer have different understanding on standard.
More experience engineer have more flexiable report, it happen in every certification body

I can not agree with you.There is no construction discription and temperature exceeded allowed T rise.It failed T test. UL Listing Mark shall not be authorized to use.
