When we drive across bridges, enter buildings, or travel on highways, not many think about the extensive testing that ensures these structures are safe. Behind every structure stands a rigorous system of laboratory testing and quality assurance that has evolved over decades. In a recent podcast episode of AASHTO re:source Q&A, Peter Unger, a pioneer in laboratory accreditation, shared his extensive experience spanning nearly 50 years in developing the international framework for laboratory accreditation that helps keep our infrastructure safe.
Pete's journey began in 1976 when he joined as assistant coordinator of the National Voluntary Laboratory Accreditation Program. At that time, a critical issue facing international trade was the redundant testing of products. U.S. exporters were frustrated that products tested in America according to European standards would be tested again upon arrival in Europe, creating unnecessary costs and trade barriers. This challenge prompted the formation of the International Laboratory Accreditation Conference, which later evolved into the International Laboratory Accreditation Cooperation (ILAC).
The development of standardized accreditation criteria became paramount. Pete was instrumental in writing ISO Guide 25, which would eventually evolve into today's ISO/IEC 17025 standard for testing laboratories. This standard provides the framework for ensuring laboratory competence globally, allowing test results from accredited laboratories to be accepted across borders. The impact on international trade has been substantial, reducing costs and streamlining the export process for countless businesses.
Throughout the interview, Pete explained the complex evolution of mutual recognition agreements (MRAs) and multilateral agreements (MLAs) that allow accreditation bodies from different countries to recognize each other's accreditations. This recognition eliminates the need for multiple accreditations or retesting of products when crossing borders. These agreements haven't just happened spontaneously – they required years of negotiation, peer evaluation processes, and building trust among international partners.
Perhaps most compelling was Pete's discussion about the impact accreditation has on laboratory quality at the ground level. He shared concerning examples of laboratories cutting corners, such as testing only one concrete cylinder but reporting values for three, creating potential public safety hazards. Accreditation provides the necessary oversight to prevent such practices, ensuring laboratories follow proper procedures consistently. This oversight is especially critical for testing construction materials, where errors can lead to catastrophic structural failures.
The interview highlighted how accreditation "levels the playing field" for laboratories, ensuring fair competition based on quality rather than shortcuts. When all laboratories must adhere to the same standards, consumers can have confidence in test results regardless of which accredited laboratory performed the testing. This consistency is vital in industries where public safety depends on accurate testing, such as construction materials, environmental testing, and food safety.
Pete also discussed his current work with organizations like the Canadian Lumber Standards Accreditation Board, helping them achieve international recognition for their accreditation programs. This recognition allows lumber certified in Canada to be accepted in markets like Japan, Australia, and the United States without additional inspection, significantly reducing costs while maintaining quality assurance.
The podcast conversation emphasized that while accreditation may seem like bureaucratic overhead to some, its true value lies in protecting public safety and ensuring that construction materials and methods meet established standards. As Pete noted, accreditation isn't about making money – it's about preventing disasters and saving lives through consistent, high-quality testing.
As our infrastructure continues to evolve with new materials and construction methods, the role of accreditation will remain essential. The systems Pete helped establish decades ago continue to adapt and provide the foundation for quality assurance across borders and industries, making our built environment safer for everyone.
