The mention of “patent pending” indicated on the meter only means that the company that commercialized the meter has submitted a patent request for its technology and that it is waiting to receive the patent. This procedure is not under Hydro-Québec’s control and has nothing to do with the meter’s certification.
Hydro-Québec meters meet Measurement Canada certification standards. In addition, they go through testing to comply with the strictest international standards. These tests fall into three categories : electromagnetic compatibility testing, climate testing and mechanical testing. All telecommunications hardware undergoes thorough climate testing.
