Abstract
Thermographic predictive maintenance is well established in industrial practice. However, thermographer qualifications vary in the extreme, causing severe problems for practitioners and users alike. The need for standardized experience and training criteria has been acutely felt in this application and in the aerospace industry application of materials non-destructive testing. A Personnel Qualification committee was formed by the American Society for Non-destructive Testing (ASNT) at the Fall 1989 conference in Valley Forge. A number of us from the thermographic community are directly involved. The committee's immediate purpose was to develop standards and test questions for inclusion in ASNT Standard Practice STC-TC-1A. The overall purpose is to arrive at a recognized thermographer certification program. George Baird was appointed chairman and Russ Mack of Dow Chemical was appointed vice chairman. They have since swapped jobs. An informal set of standards was generated shortly thereafter and circulated to the committee. Quite a bit of intensive discussion followed at committee meetings at the ASNT San Antonio conference and at Thermosense in Orlando, as well as by telephone. The main issues that developed were: 1. Experience requirements. 2. Training subjects and time. 3. Permitted activities for each leveL 4. Adherence to ASNT standard practice. A formal ballot on a standard went out to the committee in August 1990 and was approved. These draft requirements are now working their way through the various ASNT committee approvals. Examination questions are being solicited for approvaL We hope to have an approved set of training and qualification guidelines ready for use by this time next year.
