ASTM C740 Standard Practice for Evacuated Reflective Insulation In Cryogenic Service
ASTM C740低温作业中真空反射隔热标准规范
This practice covers the use of thermal insulations formed by a number of thermal radiation shields positioned perpendicular to the direction of heat flow. These radiation shields consist of alternate layers of a low-emittance metal and an insulating layer combined such that metal-to-metal contact in the heat flow direction is avoided and direct heat conduction is minimize
