520	|a"This report summarizes MxV Rail (formerly TTCI) findings on the ultrasonic testing (UT) parameters with an emphasis on the impact of cold temperatures related to non-stop ultrasonic rail flaw testing. To assess and quantify the performance of the UT nondestructive evaluation (NDE) method in extreme cold temperatures, ultrasonic velocity and density in rail steel and different fluids (couplants) were first determined by conducting experiments in the laboratory. Changes in refraction angle (shear waves) were also measured during the experiments"--Executive Summary, page iii.
