Often, PSI evaluates materials without destroying their usefulness. This testing approach, commonly known as nondestructive examination (NDE), incorporates a wide variety of technical methods. Regardless of the type of material tested or the techniques employed, the skill of the technician is the key to effective NDE.
PSI’s long history of conducting NDE began with the establishment of our Pittsburgh Testing Laboratory Division in 1881. The Pittsburgh laboratory inspected the original cables on the Brooklyn Bridge in 1881; a few years ago we inspected the replacement cables, a continuity no other testing firm can match.
PSI’s technicians undergo rigorous training and must demonstrate their proficiency before they are certified to perform these tasks. PSI experts have the knowledge and equipment to perform NDE in the field, on the project site, at the point of fabrication or manufacture, and in the laboratory.
