Providing the Crucial Facts Behind Failed Products
As previously announced here, Diversified Product Inspections’ industry-leading database and extensive inventory of exemplars and testing equipment are now operated by Product Inspection and Investigation Center (PI2C), LLC.
PI2C is an independent Tennessee company led by senior engineer Christopher Graham, who has more than 15 years of experience in product inspection, investigation, and failure analysis. With the continued involvement of experienced DPI personnel, the same core services—including product inspection, investigation, manufacturer identification, and failure analysis—are now provided through PI2C’s facility in Knoxville, Tennessee, along with collaborative laboratory facilities in Wilmington, Delaware.
PI2C also works alongside engineering partners and its affiliate company, Evidence Management Center, LLC (EMC), providing integrated product investigation, testing, and secure evidence storage solutions.
Diversified Product Inspections specializes in failure analysis, forensic investigation of product failures, and manufacturer identification. Since 1991, DPI has provided the insurance industry with timely and cost-effective product investigations. Our extensive database of product failures and inventory of more than 15,000 exemplar products allow us to assist insurers in identifying manufacturers and determining the origin of product failures.
