The analytical balance used to determine the filter weight shall meet the linearity verification criteria of Table A5/1 applying a linear regression. This implies a precision of at least ± 2 μg and a resolution of at least 1 μg (1 digit = 1 μg). At least 4 equally-spaced reference weights shall be tested. The zero value shall be within ± 1 μg.
