## Mill test pressure

2006/05/09Mill test pressure is a pressure test conducted by the mill which supplied the pipe. I would assume that it is the pressure actually used for testing the pipe in the manufacturing process, and bears no relation to your design pressure. Presumably the design pressure would be lower, particularly if used at higher temperatures.

## Mill Levy/Rate

2020/06/10The mill levy/rate is a form of a property tax that is based on a property's assessed value. The mill levy's traditionally been, and continues to be, expressed in "mills.". A mill is equal to $1 for each $1,000 in assessed property value (derived from the Latin word "mil," meaning 1,000). The mill levy is calculated by determining
