Tolerances

I seem to remember a long time ago that the tolerance on a DC10 Alt in STBY mode was checked on the daily and had to be plus/minus 30 Feet with QFE selected.

The first document above says at zero altitude tolerance is plus/minus 20 Feet. I'm not sure which aviation authority it comes from.
