The interpretation 19-40 (see attached link) says that the design temperature need not be used for computing the displacement strains.
Consider the following cases
Case 1 - A piping system requiring a steam with the Steam out temperature of 200 deg C and a design temperature of 85 deg C from solar heating that a black body is likely to have.
Case 2 - A ambient temperature piping of 50 deg C without any requirement for steam out and a design temperature of 85 deg C from solar heating.
According to the interpretation, does case 2 not require to use the design temperature for computing the displacement strains?
