1. Minimum allowable temperature for PN series flanges is -10_C (14_F). See requirements of EN 13445‐2 Annex B for applications below -10_C (14_F) with PN series flanges.
2. For applications exceeding 316_C (600_F), consult your Emerson Process Management sales office for appropriate disk material selection.

1. This material is not listed in EN 12516‐1 or ASME B16.34. Also see the Installation section.
2. The designations PN or 150 and 300 are used only to indicate relative pressure‐retaining capabilities and are not EN or ASME pressure‐temperature rating class designations.
