To round numbers according to ASTM E29-02 (incorporated by reference in § 94.5), unless otherwise specified.\n\n3. To round numbers as specified in 40 CFR 1065.1001.\n\n4. Meaning given in 40 CFR 1065.1001, unless otherwise specified. [40 CFR 1051.801 (CFR 2013)]\n\n5. Unless otherwise specified, that numbers will be rounded according to ASTM-E29-93a, which is incorporated by reference in this part pursuant to § 90.7.\n\n6. Meaning given in § 1065.1001 of this chapter, unless specified otherwise. [40 CFR 600.002 (CFR 2013)]40 CFR 86.402-78 (CFR 2018)][40 CFR 86.082-2 (CFR 2018)]\n\n7. Meaning given in 40 CFR 1065.1001.

To apply the rounding convention specified in 40 CFR1065.20(e), unless otherwise specified.\n\n9. You are required to round certain final values, such as final emission values. You may round intermediate values when transferring data as long as you maintain at least six significant digits (which requires more than six decimal places for values less than 0.1), or all significant digits if fewer than six digits are available. Unless the standard-setting part specifies otherwise, do not round other intermediate values. Round values to the number of significant digits necessary to match the number of decimal places of the applicable standard or specification as described in this paragraph (e). Note that specifications expressed as percentages have infinite precision (as described in paragraph (e)(7) of this section). Use the following rounding convention, which is consistent with ASTM E29 and NIST SP 811:\n\n10. Defined in 40 CFR 1065.1001.",
