8 E! a1 { w/ I$ \" s( z7 eProduct: a table-topped blender incorporated a self-resetting thermal cut-out. Standards: clause 20.2 IEC60335-1:1976 & IEC 60335-2-14:1984 including all amendments Situation 1. test finger having a stop plate with a diameter of 50mm according to Part 1 General requirements COULD touch the blade. Situation 2. test finger having a stop plate with a diameter of 125mm according to Part 2 Particular requirements could NOT touch the blade. Different opinions: 1. Part 2 is addition to Part 1, so the test finger of Part 1 should be done as well as the test finger of Part 2. The result is Fail because of the above-mentioned situation. 2. Though Part 2 is addition to Part 1, it is more reasonable to just use the test finger of part 2 to inspect the appliance. The result is OK. Most of our engineers agree with the above-mentioned No. 2 opinion. What about other openings? If there is a hole with the diameter of 90mm on the base of this sample (such as a hole in the base) and part 1 test finger could touch moving part while part 2 test finger is not able, most of our engineers will issue a PASS result for clause 20.2. Is it right?

# u$ t- [; x F; UOpinion 2 is correct. Concerning other openings it is correct to apply the test finger of part 1, but the standard is not clear in this matter. : e: Z. z) V( B7 I' K6 y% ]
