5. Appearance & Construction
Item Rated value Explanation
Appearance &
Construction
1. The resistive element should be covered with protective coating
that don’t fade easily. The surface of coating should avoid
unevenness, flaw, pinhole and discoloration.
2. The electrode should be printed uniformly, as shown in the
dimensions. The plating should not fade easily, and should avoid
unevenness, flaw, pinhole, projection and discoloration.
3. The electrode should be connected electrically, mechanically to
resistive element.
As far as there shall not designation especially, the following test and measurement
shall be operated under normal temperature (15~35°C), normal humidity(25~75%),
normal atmospheric pressure(
