Nondestructive Test

PTS Testing Service is one of leading NDT labs equipped with the latest technology. We perform all NDT methods on various materials and components for Nuclear, Aerospace, Maritime, Manufacturing, Automotive, Petrochemical, and Construction Industries. Some of the daily inspections we perform are radiography for welder qualification and liquid penetrant/magnetic particle on first article items. We also develop new techniques for testing a wide variety of materials, including plastics, composites, steels, aluminum, copper, and titanium alloys.

PMI ANALYSIS AND CERTIFICATION SERVICES

PTS Testing Service offers positive material identification and certification services also known as PMI Analysis and Certification Services. This Certification Service is critical to industries that are required to use high quality materials for manufactured products and components.
Material Qualification
The aerospace and nuclear industries are examples of enterprises that are often required to have product certification ensuring critical components are manufactured with the most reliable materials for durability, longevity, and safety.
Failure Analysis and Material Sorting
Often during the failure analysis process, it is necessary to positively identify the materials used during manufacturing to verify their conformance to specifications. If inferior materials are used, products may fail and cause personal injury or asset losses. To avoid potential forensic investigation or litigation, it is incumbent to verify your materials and/or manufacturing processes.
As it is a nondestructive test method and can be conducted on site, PMI is also a very convenient way of conducting verification and sorting of materials in case of mix-ups.
Improper Material Use Can Result In:
Thermal Damage
Corrosion
Fatigue Fractures
Overload Failures
Applied Technical Services PMI Analysis and Certification Services Applications Include:
X-Ray Fluorescence (XRF)
Optical Emission Spectroscopy (OES)
Inductively Coupled Plasma (ICP)
Energy Dispersive Spectroscopy (SEM/EDS)
X-Ray Diffraction (XRD)
Wet Chemistry
Ion Chromatography (IC)
 
PMI testing (Positive Material Identification) is a verification process of accurately identifying metals by determining their chemical composition.
Depending on the situation, various analytical instrumentation and testing method maybe used to accurately determine metal composition. For quick alloy identification of materials our handheld XRF unit is used. In other situations, especially when assessing composition of lighter elements, the OES or ICP units are used to evaluate samples. Often times, for a comprehensive material property identification, other characteristics of the metals are evaluated, which include tensile strength, yield strength, elongation, hardness, etc. Our team of chemists, metallurgists and engineers work together to ensure all your testing needs are met in a timely manner. From the aerospace to the nuclear industry, PTS Testing Service has assisted a wide array of clients with their PMI needs.
Common Material Types for PMI Testing Include:
Alloy Steels
Aluminum Alloys
Stainless Steels
Nickel Alloys
Titanium Alloys
Copper Alloys
Cobalt
