HEAT RISE & DERATING CURVES GENERATED ACCORDING TO EIA-364-70D, METHOD 2
Heat Rise & Derating mated pair Single Phase 13-E4 equipped with Size 16 Power contacts This procedure establishes the test procedures for determining temperature rise versus current. Heat Rise explains how the current passing through generates heat at the contact point, causing the temperature to rise while derating tests explains how the maximum current rating of the contacts decreases as the ambient temperature increases. Overall, this gives a good overview of the connector performance. The mated samples are placed in an enclosure to reduce air disturbance. The connectors are powered with a serial circuit between several contacts, according to the arrangement. The current is applied by step of 5 A, starting from the current prescribed for the contact resistance measurements. During the current application, the heating of the sample is measured with thermocouples connected to an acquisition unit.
