A New Requirement Is Coming. Make Sure Your Lab Is Ready.
AASHTO R18-26 is a significant revision, and it doesn't just tweak the wording. Section 6.9 introduces a completely new requirement: your lab must maintain a written policy for how you select and evaluate calibration service providers. Sections 6.2 through 6.5 also tighten what your calibration and maintenance records need to include, right down to matching test points to how equipment is actually used in practice.
This checklist was built for the people running accredited CMT labs who need a fast, reliable way to see where their calibration program stands against the new requirements, without reading through R18-26 section by section.
Inside you'll find:
- A plain-language walkthrough of the equipment calibration, standardization, check, and maintenance requirements in Sections 6.2–6.9
- The new Section 6.9 requirement to document how you select and evaluate your calibration service provider
- A quick glossary clarifying "calibrate," "standardize," and "check" so you can read your own procedures and records with confidence
- The January 2027 assessment timeline, including what to do if you're adopting the changes early
