The latest content of acoustic emission code GB/T18182-2012 are shown in this paper. The differences of GB/T18182-2012 and GB18182-2000 are summarized. Acoustic emission method was used to inspect the whole process of tensile specimen test under the temperature of 0°C, −20°C and −50°C. Based on the characteristics of the signal of different temperature condition, some difference of these signals was analyzed and discussed. By using the above result, acoustic emission was applied to inspect a drikold storage vessel.
