Trial operation test of the stirred-tank reactor

Recently, we delivered several reactors to a semiconductor company, and the client (a foreigner) raised a series of concerns regarding these reactors: 1. He questioned the fact that our equipment hadn’t been polished; he pointed to a mirror-polished device nearby and claimed that our matte finish meant no polishing had been done – it was like a scholar facing a soldier, with no way to justify his position. 2. During the trial run at the client’s site, we observed the equipment’s performance: it operated smoothly, without any vibration or noise, and the motor reducers were functioning properly. Due to the limitations of the site conditions, we couldn’t use any instruments for testing. The customer said that the free end of the mixer swings a lot, and asked us to measure the swing amount at the lower end. I asked in return, how do we measure it? He said to measure it inside the equipment? (That’s crazy; this is a mixing reactor, not a meat grinder.) No one in the entire industry does it this way. 3. After some discussion, I suggested following the standard criteria for acceptance, but the customer said, \"Don’t talk to me about any standards or regulations; what I see is that the degree of swing is quite large... What should I do in such a situation?\" Also, how is the swing amount of the free end of the stirrer in the reaction kettle measured?
