A manufacturing date code or four digit of number shall be marked on the protect coating.
See para.2. (3)
Rated dissipation is based on continuous full load operation at rated ambient temperature of 70deg C.
For resistors operated at ambient temperature in excess of 70deg C, the maximum load shall be derated
in accordance with the following curve.
The d.c. or a.c. r.m.s voltage shall be calculated from the following expression.
When the rated voltage exceeds the limiting element voltage, the limiting element voltage shall be the
rated voltage.
