ii Certain commercial entities, equipment, or materials may be identified in this document in order to describe an experimental procedure or concept adequately. Such identification is not intended to imply recommendation or endorsement by the National Institute of Standards and Technology, nor is it intended to imply that the entities, materials, or equipment are necessarily the best available for the purpose. Abstract Overall uncertainties are evaluated for the certification of transmittance density (absorbance referred to air) and regular spectral transmittance for solid neutral density filter Standard Reference Materials by means of a transfer spectrophotometer. Traceability is asserted by means of comparison measurements to a recognized reference spectrophotometer. The uncertainties are evaluated without bias correction, using the combination of the legacy combined standard uncertainty values with uncertainty components for the measured bias, the standard uncertainty of this measured bias, and the standard uncertainty characteristic of simple replication for a single measurement using the transfer spectrophotometer. Numerical results are given, and are anticipated to be the values initially quoted on certificates and in reports of recertification. However, these values are subject to change upon future adjustment of estimated uncertainty components for the filters or changes in the observed bias with future determinations.
