It introduces the necessity and objective of the hydrostatic test. By comparative analyzing the RCC - M (2000 + 2002), RCC - M (2007), ASME 1 (2010) in hydrostatic test pressure, water temperature , pressure holding time and the acceptance criteria, the hydrostatic test pressure and water temperature for nuclear safety class 2,3 pressure vessel are given specific recommendations.%介绍了水压试验的必要性和目的性,通过对RCC -M(2000版+2002补遗),RCC -M(2007版),ASMEⅢ(2010版)中水压试验压力、水温、保压时间和验收准则相关规定的对比分析,对核安全2,3级压力容器水压试验压力、水温给出了具体建议.
