Initial TUS

       For the continuous furnace, if want to improve the highest speed, is initial TUS needed?

      No other changes for the furnace.

      Thanks!

Dear Lucysun
If you use Plane method,change highest speed should need initial.
Or Volumetric method,you not.
See AMS2750E 3.5.14

I think you should do the TUS test.

I don't think AMS2750E 3.5.14 is useful for his question.

For my opinion, initial TUS is needed for this case.
Because your furnace is continuous, the speed is important factor for the uniformity of air temperature and material temperature.

According to the specification as reference,
1. AMS2750 3.5.8  During TUS, all paramaters shall reflect the normal operation of the equipment in production. But now you speed up it, and the initial TUS paramater is different from now.
2. AMS2750 3.5.15.2.1 Continuous furnace throughput shall be that normally used for processing. But now you speed up it, and the initial TUS paramater is different from now.
