It would be nice since we all must use the same mixtures now per NFPA 13 that some data could be included in the next edition.

The viscosity range as a function of temperature would be a nice chart. I am sure the calculation procedure required is not followed or this information would be available. Olie Olson, P.E.

The manufacture we use for our pre-mixed solutions does not have much information on this and I finally need to do a calculation with this. I would assume the values should be close to the freezing point of the solution?
