Destructive Physical Analysis

Destructive analysis of a part can be used to identify its baseline construction and constituents, as well as to determine variations in the manufacturing process which may affect quality and reliability. DPA can be implemented as an on-going program to assess samples of incoming part lots prior to release in manufacturing. Supplier follow-up may be recommended.

Are you certain that the materials and components that you purchase are genuine and really meet your needs? In today's rapidly changing world of suppliers and middlemen can you really afford to "trust the provenance and datasheet"? Datasheets often do not provide construction details that you need to know to ensure you are meeting your customer requirements. Is it prudent to assume that the materials and components that you buy this year will perform exactly like those you bought last year?

The only way to be certain of what you are buying is to analyze it! At the RAL® we can use our full range of analytical capabilities and areas of expertise to determine the exact construction, composition, and quality of almost any materials or components. As always, the RAL® can tailor an analysis and response format to suit your needs.



Destructive Physical Analysis can be performed on a component as an initial evaluation. Such an analysis is performed to:

  • Establish a construction baseline for component qualification or future analysis.
  • Design or Supplier evaluation.
  • Select vendors and components.
  • Evaluate new technologies and custom parts for integrity of construction, quality, and reliability
  • Identify counterfeit components.

A DPA can also be used as a routine recurring analysis of a previously analyzed part type to:

  • Identify deviations in supplier process or design of component
  • Recommend lot disposition and corrective action
  • Independently check the quality of the supplier process
