5.4.4 Regeling luchtvaarteenheden BES

Attachment of letters to a unit symbol as a means of giving information about the nature of the quantity under consideration is incorrect. Thus MWe for ‘megawatts electrical (power)’, Vac for ‘volts ac’ and kJt for ‘kilojoules thermal (energy)’ are not acceptable. For this reason, no attempt should be made to construct SI equivalents of the abbreviations ‘psia’ and ‘psig’, so often used to distinguish between absolute and gauge pressure. If the context leaves any doubt as to which is meant, the vord pressure must be qualified appropriately.

For example:

”. . . at a gauge pressure of 13 kPa’.

Or ?. . . at an absolute pressure of 13 kPa’.
