la norma te habla de:
Plugs, Receptacles, and Cable Connectors of the Pin and Sleeve Type
en la sección 5 te habla de los métodos de test de estos:
5.20 Endurance with load
5.20.1 Devices intended for current interrupting shall withstand, without harmful effects as described in Clause 5.20.8, the mechanical, electrical, and thermal stresses occurring in normal use.
5.20.2 Devices under test shall be operated manually or mechanically at rated voltage and current at a rate no greater than 10 cycles per minute.
5.20.3 The test shall either be conducted using direct current or be conducted using alternating current if the device is marked in accordance with Clause 7.1.6.1. When alternating current is used, the power factor of the load shall be from 0.75 – 0.80.
5.20.4 For dual-rated devices, a test on ac may be waived if acceptable results have been obtained from an equivalent or higher volt-ampere test at a dc potential that is equal to or greater than the ac potential rating.
5.20.5 If the test is run mechanically, the rate of operation shall not be greater than 10 cycles per minute, with an average velocity of 760 ±80 mm (30 ±3 inches) per second in each direction.
5.20.6 A rate of operation having a lower average velocity may be used if agreeable to all parties concerned.
5.20.7 The total number of operating cycles shall be in accordance with Table 16.
5.20.8 During the test, sustained arcing shall not occur. After the test, the devices shall not show:
a) Wear impairing the further use of the device;
b) Deterioration of enclosures or barriers;
c) Damage to the entry holes for the contacts that impairs proper working; and
d) Loosening of electrical or mechanical connections.
Creo que la cosa esta clara y no tiene siquiera que ver con el factor de potencia pero si con sus consecuencias. Repasa la norma, no me apetece leer el tocho y expon realmente tus conocimientos para no solo darte la respuesta sino saber cual es tu pregunta exacta.
