Our standard of excellence works for you

"Nobody ever questions us when we submit our accreditations for a project based on procedures, proficiency sampling or lab audits. It gives us a good feeling that every time we do an audit, it will meet the minimum standards that are accepted in the Northeast."

  • A Day in the Life of a Quality Analyst

    In 2010, I wrote “A Day in the Life of an Assessor” about what it was like to be an AASHTO re:source Assessor on the road. Almost 4 years later, as a Quality Analyst (QA), I spend most of my time in the office working with laboratories in the AASHTO Accreditation Program (AAP).

  • AASHTO re:source ISO/IEC 17025 Assessment: What to Expect and Tips to Prepare

    A Quality Management System serves as an important driving force toward achieving quality of products and services. Including the ISO/IEC 17025 standard to your scope of accreditation is a formal recognition of the lab’s technical and organizational competence. The decision to pursue the ISO/IEC 17025 quality standard should not be made lightly or without complete clarity, as there is a cost to the business. Conforming to this rigorous standard demonstrates the lab’s willingness to go above and beyond the customer’s minimum requirements to provide quality service. Whether it’s your first time or something your lab has been through in the past, preparing for an ISO/IEC 17025 assessment can be overwhelming and nerve-racking. This is because there are many pieces to the ISO/IEC 17025 puzzle, and the fear of something not working seamlessly in real-time is quite tangible. Following the five tips presented in this article and addressing them ahead of time can make the lab assessment seamless, straightforward, and a vindication of the lab’s good practices.

  • Evaluating Competency: How do you measure up?

    Raise your hand if you’ve received a nonconformity related to training and competency evaluations. Good. The first step is admitting it. Whether the finding has been minor and easily resolved, or it has required you to revamp your entire training and competency evaluation program, just about everyone has been there before. When it comes to the array of requirements, options, and best practices, there can be a lot of confusion about what you are supposed to be doing. AASHTO R 18 and ASTM quality system standards such as, C1077, D3666, and E329 can all have differently worded requirements, which can add more confusion to the issue. This article will help hone your understanding of documenting competence and interpreting the requirements of quality system standards.

  • Get to the Root of the Problem: Root Cause Analysis (RCA) Explained

    Ever get tired of those pesky dandelions in your otherwise lush yard? The weeds are the obvious problem, but have you ever thought about the underlying, or “root,” cause? That might not be so obvious. In reality, there are usually multiple “roots” to most problems, even in the construction materials testing (CMT) industry.

  • How to Resolve AASHTO re:source and CCRL Report Findings

    While a laboratory may have effectively resolved a nonconformity internally, it is also important to understand what forms of evidence need to be submitted to the AASHTO Accreditation Program. In some cases, the laboratory’s proposed resolution does not address, or resolve the nonconformity, and further corrective action(s) will be required. These examples will provide you with guidance on how to best resolve the various types of nonconformities and provide you with more insight into why you may be asked for additional supporting information.

  • New Tools for Specifiers: the Missing Piece of the Accreditation Puzzle

    A specifier is any entity that requires laboratory testing to be performed by an agency that participates in one or more of AASHTO re:source’s programs. Specifiers can include departments of transportation, local municipalities, or even corporate offices that manage several branch laboratories. Some of AASHTO re:source’s current specifiers include the Federal Aviation Administration (FAA), the California Division of the State Architect (DSA), and the United States Army Corps of Engineers (USACE). Being a specifier can be challenging, and requires constant review of ever-changing laboratory information, such as proficiency sample ratings or accreditation status. In the past, tracking information for one hundred, ten, or even three laboratories was a daunting task.

  • Quality Corner: ISO/IEC 17025 Accreditation

    Did you know that AASHTO re:source offers on-site assessments and AASHTO offers accreditation for International Standard ISO/IEC 17025? You may have at least heard of this standard by now, but maybe you don't know much about it. The title of the standard is "General Requirements for the Competence of Testing and Calibration Laboratories." But how does that differ from AASHTO R 18, "Establishing and Implementing a Quality Management System for Construction Materials Testing Laboratories," which is the basis for accreditation through the AASHTO Accreditation Program (AAP)? How can a laboratory become accredited for ISO/IEC 17025? What are the benefits? Let's take a closer look.

  • Selecting Competent Subcontractors and Vendors: What to Consider and How to Document It

    You should be proud that your laboratory has been through an on-site assessment and has completed the requirements of the AASHTO Accreditation Program. Once accreditation is granted, your laboratory’s accreditation status is available on-line from the Directory of AASHTO Accredited Labs. Your customers can view this accreditation listing and will likely use it as a method of determining whether or not you are competent to perform a given task. So, it makes sense that your laboratory also has a policy for ensuring the competency of the subcontractors and vendors that you use.

  • Technician Certification Requirements in ASTM Standards

    It has been over a year since we started to request technician certification information during a laboratory’s annual review for AASHTO accreditation rather than during the on-site assessment if the laboratory is accredited for ASTM C1077, D3666, D3740, or E329. This change was made to improve the consistency of our assessment of laboratory conformance to the ASTM quality system standards that require technician certifications. A consistent evaluation ensures that all AASHTO-accredited laboratories throughout the country are treated fairly and that our program can better meet the needs of the agencies that specify accreditation for these standards.

  • The History of the AASHTO Accreditation Program

    The AASHTO Accreditation Program (AAP) was established in 1988 to provide a mechanism for formally recognizing the competency of testing laboratories to perform specific tests on construction materials. Some of you who know the history of the industry may be surprised that the AAP is so young because the AASHTO re:source and CCRL (Cement and Concrete Reference Laboratory) have been around much longer. In fact, the AASHTO re:source was founded in 1965 and the CCRL was established in 1929, as the Cement Reference Laboratory (CRL). The AASHTO re:source and CCRL are collectively known as the Construction Materials Reference Laboratories (CMRL).
