| ===Standardized test methods used by construction and engineering laboratories===
| |
| Like other materials testing labs, well-run construction and engineering labs are dependent on standard-based analytical methods developed with the input of the international community. The use of those standardized test methods may be mandated as part of the lab maintaining accreditation to a laboratory-based standard such as ISO/IEC 17025 or ISO 9000, or voluntarily adopted by the lab as part of an organization-driven set of industry best practices.

|
| |
| Interestingly, it appears that labs performing construction and geotechnical testing have roughly a 50 percent chance of being ISO/IEC 17025- or ISO 9000-certified, with those not having this certification opting for more industry-relevant or localized certifications with, for example, American Association of State Highway and Transportation Officials (AASHTO) or a state-level department of transportation (DoT). (Source: personal research.) If the lab is limiting its clientele to within the state, it may make more sense to simply focus on something like AASHTO accreditation for the lab's specific set of tests, as the costs of getting accredited to ISO/IEC 17025 for local work may not make sense. This gets even more complicated as accreditation standards can vary across cities and states, as well as across more national and internationally focused accreditation bodies. This variance can be slight, but just enough to force these types of labs to certify with multiple entities in order to expand business, increasing costs further. All this heterogeneity in the materials testing accreditation landscape—and thus in determining which standard test method to use—has led to calls for a more uniform federal-level recognition program for these and other materials testing labs, one that relies on a more unified, industry-backed set of test methods that will remain applicable across most local, state, and federal borders.<ref name="NRCStand95">{{Cite book |date=1995-03-15 |title=Standards, Conformity Assessment, and Trade: Into the 21st Century |author=National Research Council |url=http://www.nap.edu/catalog/4921 |chapter=Chapter 3: Conformity Assessment |publisher=National Academies Press |place=Washington, D.C. |pages=65–102 |doi=10.17226/4921 |isbn=978-0-309-05236-8}}</ref><ref name="ArnholdConfom">{{cite web |url=https://ex-magazine.r-stahl.com/article/detail/konformitaetsbewertung-in-den-vereinigten-staaten |title=Conformity Assessment in the USA |author=Arnhold, T.; Berner, W. |work=Ex-Magazine |publisher=R.
