Massimo,
Just to underscore what others have stated, long ago in one
of the resistor mfr's catalogues, there was a discussion of
this topic. Essentially, do not violate the DC wattage
rating of the resistor based on a 1 second time period.
As an example, a 1W, 1 Ohm, carbon composition

Massimo,
All the tests that I've seen for evaluating the peak-pulse-power
handling capabilities
Massimo,
All the tests that I've seen for evaluating the peak-pulse-power
handling capabilities of resistors are based on charging a bank of
capacitors to a high voltage, then applying this energy (E = 1/2 * c * V
* V) to the part/equipment-under-test through a low-resistance
low-inductance

Does anybody out of there know what are the methods to evaluate
resistors pulse loading capabilities (maximum peak pulse voltage without
failing to open circuit)? Is there any standard models? This could be
very useful to design the power supply
