Products that are certified to the ANSI standard is much different than products that meets or exceed ANSI standard. Certified to ANSI means that the product has been tested and certified by a third party testing facility that have meet all the requirements of ISO 17025. The products undergo all the testing that is set forth by the ANSI standard to qualify as certified product. This gives the user an extra level of assurance that the product will perform as designed. On the other hand, if a product has the term ”Meets or exceeds” on the labeling or instruction manual, it simply means that the manufacturer has tested the products internally usually without a 3rd party verification. It’s important that you as the user of the equipment understand these difference so that you can make an informed decision on the products you are using or specifying to use in the field.
