Positive Material Identification

Increased emphasis on safety and reliability requires a more stringent program of material verification to eliminate human error and ensure that materials meet design specifications. To meet this demand, Spectrum uses Positive Material Identification (PMI) as a means of determining the elemental composition of test materials.

Depending on the requirements, our PMI utilizes either a portable X-Ray fluorescent analyzer or Spark Emission Spectrography to ascertain the different alloys that comprise a particular metal. PMI can be performed on site for almost any size or shape of ferrous and non-ferrous metallic materials, such as welds, castings, forgings, valves, machined parts, pressure vessels, plate material, structural steel or pipe. Both new equipment and equipment already in service are candidates for PMI.
