Accuracy of Thermal Expansion Properties in ASME B&PV Code

Introduction

Thermal strains listed in the ASME Boiler & Pressure Vessel Code are given in units of mm/m and to 1 decimal place accuracy. For small temperature rises, e.g., 20oC to 50oC, the thermal strain can be as low as 0.3mm/m. This implies an accuracy of +/- 16.6'% which seems rather large given that thermal strains can, presumably, be measured to much greater accuracy.
