It is suggested that the component be tested at the system have full automotive IATF16949 certification. The PM part number dimensions are level, to verify the temperature rise of the component during system operation. 100% tested in production but do not necessarily meet a product capability index 4. The part temperature (ambient+temp rise) should not exceed 125C under worst (Cpk)> 1.33 and therefore may not strictly conform to PPAP. case operating conditions.
