It's related to your specifications or code which you used for example if you work in power station, the used code is B31.1-2007 and you shall refer to 136.4.4 for the DPT acceptance criteria

Otherwise some cases order you to use the specifications of the client which has special acceptance criteria

HI, Temperature limit as per ASME Section SecV,shall be as follows. T-652 Techniques for Standard Temperatures As a standard technique, the temperature of the penetrant and the surface of the part to be processed shall not be below 40°F (5°C) nor above 125°F (52°C) throughout the examination period. Local heating or cooling is permitted provided the part temperature remains in the range of 40°F to 125°F (5°C to 52°C) during the examination. Where it is not practical to comply with these temperature limitations, other temperatures and times may be used, provided the procedures are qualified as specified in T-653. Acceptance criteria: It shall be as per ASME Section-VIII,Div1-Appendix-8.In no case temperture shall be less than 5 degree celsius for LPT.If the surface temp.is less than that it shall be heated to maintain the temp.limit as per code.
