  • 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.

    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.

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.

  • The Last Guy Didn’t Write Me Up On That!

    Gigs and dings and bones to pick…oh my! We at AASHTO re:source refer to these things by their proper name… “nonconformities.” So what’s the story behind why the last assessor didn’t “write you up” on something? That depends on lots of things – the test methods, the laboratory’s personnel, random sampling, our learning curve, miscommunication, and just plain human behavior. Let’s dig a little deeper into why two assessments of the same laboratory most likely will never be identical.

  • Reality Calibration

    I have a confession to make. Although I’ve been an outspoken critic of “Reality TV,” there is one show that I sometimes watch with my wife. It’s called “Married at First Sight” and in each season six people agree to participate in an extreme experiment: Each pledges to legally marry a complete stranger. No dating, no talking, no getting-to-know-you period. It’s not just that they have never met; they don’t know a thing about their future spouse, haven’t even seen a glimpse of them, until the actual marriage ceremony. (I’m not sure how this actually resembles reality, although my wife sometimes thinks that I’m an alien.) You can probably guess how these marriages work out: they usually don’t. The couples struggle because they don’t know how each other will respond to certain situations. How many of us would agree to that type of arrangement?
