Al. Bailey et Lj. Lamont, A STANDARD PROCEDURE FOR ACCELERATED TESTING AND MEASUREMENT OF YELLOWING BY LIGHT IN PAPERS CONTAINING LIGNIN, Tappi journal, 76(9), 1993, pp. 175-180
The results of a newly developed method for accelerated testing of yel
lowing by light with controlled irradiation, temperature, and humidity
are similar to those achieved by lengthy exposure to fluorescent ligh
ts under controlled conditions.
