IEC 61270-1:1996

Applies to capacitors for microwave ovens operating at rated a.c.
voltages of up to 3 000 V and a superimposed d.c. voltage of up to
1.13 times the value of rated a.c. voltage.  Relates specifically
to capacitors with a metal case and an upper rated maximum
temperature of up to 100 °C, non-self-healing, with metal foil
electrodes and dielectrics of paper and/or plastic, impregnated
with a suitable oil.  This part contains uniform rules regarding
performance, testing and rating and specific safety rules.
