Narrative:

During winter operations at lfpg; we were cleared to taxi to the northeast remote deicing pad for deicing. After more than a 30-minute wait; we were cleared in to the pad and switched radio frequencies from ground control to the deicing coordinator. We then configured for deicing. Both engines were kept running at idle per lfpg SOP. Prior to entering the pad; the captain was performing engine run-ups every 15 minutes per the flight manual. While in the pad; it became necessary to perform another run-up. We contacted the deicing coordinator and informed him of our requirement to run the engines up beyond idle and asked if we were clear to do that. The deicing coordinator at first did not understand the request. After at least 2 other transmissions; the coordinator told us he understood and that yes we were cleared to do our engine run-up. The #1 engine was run up first. Immediately after the #2 engine run-up; the coordinator asked us to return our engines to idle. He then asked why we had not remained at idle. We explained that we had asked and he had cleared us to conduct a run-up. He stated that he had not. At some point; our carrier's contract mechanic who supervises the process got on the radio. It became apparent that the coordinator had limited english and although authorizing our request; never fully understood it. We were informed that damage had been done to one of the deicing trucks. Deicing was completed and the remainder of the flight was uneventful.
