Opacity of paper or board

The ISO 2471 standard is followed to determine the opacity (paper backing) of paper by diffuse reflectance.

The test is suitable for papers and boards that contain fluorescent whitening agents, as long as the UV content of the radiation incident on the test piece has been adjusted using a fluorescent reference standard as described in ISO 2470‑1.

The method is not suitable for colored paper or cardboard that contains fluorescent dyes or pigments.
