Positive Material Identification (PMI) is a non-destructive testing (NDT) technique used to determine the chemical composition of materials, particularly metals and alloys. PMI is crucial in various industries, including oil and gas, aerospace, manufacturing, and construction, where knowing the exact material composition is essential for safety, compliance, quality control, and maintenance purposes.
