What term describes the phrase 'acceptable to the authority having jurisdiction'?

The phrase "acceptable to the authority having jurisdiction" refers directly to the term "approved." This means that whatever has been evaluated or reviewed by the authority meets all necessary codes, standards, or regulations set forth by that authority. This approval implies that the design, installation, or equipment has been found satisfactory and compliant with applicable laws and safety standards, ensuring it can be legally operated within the jurisdiction.

In regulatory contexts, having an item deemed approved can lead to its use in practice and can signify that it has passed inspections or has been validated through testing processes, aligning with the safety and performance expectations outlined by governing bodies or national standards. Hence, "approved" specifically captures this concept of official acceptance and validation by relevant authorities.
