Significance and Use | ||||||||||||||||
The procedure described in this practice is designed to provide guidance for evaluating the effects of outdoor exposure on varnishes applied to wooden substrates. For many products, fixed angle exposures will produce higher degradation rates than the normal end use of the material. The degradation rate produced by this procedure depends on the season of the exposure and geographical location. Because outdoor weather conditions vary from season to season and year to year, this practice is not reliable for establishing absolute performance ratings for varnishes. The practice should be used only for comparing the relative performance of varnishes exposed at the same time and same location. |
