4.2 te Variable PTRO expressed in “kPag” unit According to the item 3.2.1 of the ISO 31-0 no measure condition (std, gauge etc) is allowed to be expressed together with its respective unit. We suggest using “gauge kPa”. Also, since “kPa” involves large numbers, we suggest using “MPa” for a better unit representation.

Accepted in principal, changed to “gauge kPa” in all

places where appropriate
