Dear All.

I have question about the Standard of NFPA 13, 2016 edition. I'm not sure the numbers of density. Is it correct ? Please see the attached information. Please recheck and let me know.

Technically 1.1 mm/min/m² is correct. If 12.2 mm/min is multiplied by the conversion from 1 ft² to 1 m² (0.092903) the result is 1.1 mm/min/m².

Hi.
I'm not sure the numbers of density. Please see the attached information. I think the density should be 12.22 mm/min.
And, I've compared density values with graphs in standard. It has a density as 12.22 mm/min. Please recheck and let me know.
