About Carlson Testing Inc.
Carlson Testing, Inc. performs at a “world-class” level for our clientele. A major reason for this is our commitment to obtaining and operating under some of the strictest certifications and accreditations, in our industry.
Why is this important to you? This is important because it is common practice to question the competency of the inspection and testing agency and/or their inspectors and technicians when materials fail to meet the quality requirements of a project.
We, and our clients, must be confident that our results are an indication of a “true” material failure and not a result of poor quality control practices. One of the most important aspects of our job is to instill confidence in our clients. Our services and final results have to be detailed and accurate, as well as, reliable and repeatable.
To help achieve this level of confidence, we have sought out and obtained numerous national and local accreditation and certifications. These include:
