TER’s or Technical Evaluation Reports are evaluation of a product’s performance. They are not intended to approve product for a specific application, but rather provide limiting values based on installation options.
TER’s don’t provide the full assembly or installation of a product and should be used in conjunction with manufacturer specifications, building plans, and other limitations of specified components (such as anchor installation requirements).
TER’s also don’t have information about installation at a given address. That’s up to someone to interpret the information on the TER for use at a specific location. Engineering Express can also do that, but that’s outside the limits of published TER’s.
TER’s also don’t have a universal approval when published. Each document must be signed and sealed by the evaluating engineer to be valid for use per code. This mechanism helps limit misrepresentation of the information contained in the report.
Think of a TER as the approval rating for a ladder, like ‘300lb limit’. no matter where that latter goes on earth it is subject to break above 300lb (with a reasonable safety factor). The ladder rating doesn’t state the names of people or types of industries it’s approved for, just like the TER states a wind pressure performance limit and not the cities, houses, or types of structures it can be used with.
