    There currently is no mention of the type and accuracy of the barometer in the methods D2699. These parameters were once found in the old methods D357 and D908 but were removed some time in the 90s and the great mercury purge of a few years ago. There are over 70 references to barometric pressure in the methods but no minimum specifications that would satisfy the methods requirements.
