(1) Process temperatures above 185 °F (85 °C) require derating the
ambient limits by a 1.5:1 ratio. For example, for process
temperature of 195 °F (91 °C), new ambient temperature limit is
equal to 170 °F (77 °C). This can be determined as follows:
(195 °F - 185 °F) x 1.5 = 15 °F,
185 °F - 15 °F = 170 °F
(2) 212 °F (100 °C) is the upper process temperature limit for DP
Range 0.
with Coplanar Flange -40 to 250 °F (-40 to 121 °C)

(3) 220 °F (104 °C) limit in vacuum service; 130 °F (54 °C) for
pressures below 0.5 psia.
with Traditional Flange -40 to 300 °F (-40 to 149 °C)

(4) -20 °F (-29 °C) is the lower process temperature limit with option
code P0.
with Level Flange -40 to 300 °F (-40 to 149 °C)
