The first one focuses on the aging mechanism, while the latter describes the available artificial aging procedures for bituminous binders and mixtures.
They analyzed the direct impact of microcracks on the module power and the consequences after artificial aging. The approach of artificial aging they adopt was 200 humidity freeze cycles.

For varnished, painted, or otherwise coated wood, it is difficult to compare color results described in the literature because of varying substrate (species), coatings, coating thickness, UV intensity, and the absence/presence of humidity/water with artificial aging or weathering.
Since 1996, the chemical/physical department at the laboratories in Ciyitanova Marche has also been conducting in-house artificial aging tests (QUV).
Wilful deception, stylistic mimicry, artificial aging, factious provenances, false signatures--all of these characterise forgery.
(14) Moreover, artificial aging methods allow for assessment of the degradation of materials in a short period that would otherwise take months or even years of use in the oral cavity.
