In this paper, we provide templates of measurement uncertainty sources expected to appear for average prompt- and total-fission neutron multiplicities, $$ \overline\nu_p $$ and $$ \overline\nu_t $$, for the following measurement types: absolute manganese-bath experiments for $$ \overline\nu_t $$, absolute and ratio liquid-scintillator measurements for $$ \overline\nu_p $$. These templates also suggest a typical range of these uncertainties and their correlations based on a survey of available experimental data, associated literature, and feedback from experimentalists. In addition, the information needed to faithfully include the associated experimental data into the nuclear-data evaluation process is provided.
