How Much Should Laboratories Spend on ISO 17025 Accreditation?

Scene inside a laboratoryLaboratories in mainland U.S. that require accreditation from the American Association of State Highway and Transportation Officials (AASHTO) would need to spend $2,500 for a full assessment.

Accreditation would be necessary in some states such as Illinois, due to an enhancement program that will require equipment to be compliant with the standards of ISO 17025. In Chicago and other cities, accredited labs like Acme Scale Technologies would have an advantage since the ISO standard reflects their competence.

Cost of Compliance

AASHTO said that upon a successful accreditation, labs would need another surveillance after around one year from being certified. This costs an additional $1,800. Succeeding assessments would need to be done alternately between full and surveillance tests, which occur at an interval of 27 months.

Labs that are also certified with the AASHTO Accreditation Program (AAP) can pursue an ISO 17025 assessment. While AAP shares similarities with the ISO standard, the latter provides additional requirements such as uncertainty of measurement, purchasing, contract review and client feedback.

Why It Matters More

In Illinois, the state transportation department’s Illinois Transportation Enhancement Program plans to invest around $36 million for bike and pedestrian projects. Hence, equipment testing would be necessary to carry out these development plans as part of the

Some of the projects include the Hillside bike trail and pedestrian bridge; a new pedestrian bridge at 43rd Street over Lake Shore Drive; a new multipurpose trail for the Mississippi River-Rock River area; and a Clarendon Hills downtown renovation. Each of these projects will receive a $2 million budget for construction.


Labs need accreditation to reflect their competency in their respective industry or field. From weighing equipment to precise measurement, an ISO 17025 accreditation proves that you comply not only with global regulations and standards, but also have the ability to provide accurate testing and calibration data.
