- 1930, Technical Association of the Pulp and Paper Industry, Technical Association Papers - Volume 13, page 75:

- 1936, The Journal of the American Leather Chemists Association:
- The use of a fadometer is to be recommended, but because of its limited use in the average leather laboratory the adoption of the ordinary exposure test is considered best.
- 1940 August 19, “River Rouge”, in LIFE, volume 9, number 8, page 45:
- A hundred hours in the fadometer equals half a year in Florida sunshine.
- 1957, Milton Jacobs, Fabrics and Fibers for Passenger Cars:
- Essentially, these consisted of placing fabric swatches under the light of the Florida sun or of a fadometer, and then examining them to determine the degree of fade.
