ETSP-PCT series are a Pressure Cooker Test (PCT) system also called an Autoclave Test or Pressure Pot Test (PPOT).

ETSP-PCT series assess the ability of a product to withstand severe temperature and humidity conditions.  It is used primarily to accelerate corrosion in the metal parts of the product, including the metallization areas on the surface of the die.

It also subjects the samples to the high vapor pressure generated inside the autoclave chamber.
