1 National Training Society LPI Recertification Written Instruction Guidelines Fill in ALL reports and diagrams clearly with all information attached. Make sure that everything is neat and legible. These instructions below are from the NRCan recertification study guide for recertification examinations: NDT Written Instruction Write a detailed instruction for one of the tested specimens. The written instruction must be completed in a manner that will permit another inspector to follow your steps and duplicate your results. It should include: a) Scope of the inspection. b) Personnel qualifications requirements. c) A description of the exam specimen. d) A list of equipment, reference standards, and accessories used. e) A description of the calibration procedures specific for the test specimen. f) A description of the inspection procedures specific for the test specimen. g) The instrument settings at the time of inspection. h) Reporting of the results. Note: Although to write instructions a candidate may obtain inspiration from the general information accompanying the test specimen, he or she should remember that the NDT Certifying Agency requires a specific instruction to inspect a specific specimen. Please make sure to read the test booklet that comes along with your test specimen. Some details and inspirations can be taken directly from this.
