MRT also conducts Nondestructive testing (NDT) testing to ensure quality and to detect possible defects using NDT methods of inspection. MRT also has a full-time Level II NDT Inspector on staff to limit down time. Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for various faults, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed, we’ll know if the part can still be used.

MRT applies testing criteria in accordance with applicable specifications or standards and valuate results by using Mag particle or Dye penetrant testing methods.
