During a recent review of pellet heater compliance test reports, the Measurement Technology
Group has uncovered an error in determining the appropriate Medium Burn Rate Category when
using ASTM E-2779 for compliance pursuant to 40 CFR 60, subpart AAA. Specifically, the
method requirements in section 9.4.1.2 and Table 1 of that test method incorrectly require that
the Medium Burn Rate Category must fall below 50% of the maximum burn rate. This is not
correct as this requirement assumes then that zero is the other bound for determining half of the
maximum.
