    The Principle of Reciprocity – Its Value as a Tool in Weathering

    January 24, 2022 | Oscar Cordo

    In our niche weathering industry, there are some who believe that reciprocity is a misguided notion. Well, the principle of reciprocity is a valid scientific premise, that when observed, allows researchers to reduce test times by increasing the irradiance of the accelerated weathering test method used. If one wishes to reduce their test time, testing if reciprocity is observed must be performed before making predictions about test duration at higher irradiances.

    The Truth About Rack Back Spray and Its Use in SAE J1960/SAE J2527

    August 2, 2021 | Oscar Cordo

    It is no secret that moisture is a major degradation mechanism for many materials. Relative humidity, rainfall, and one-off applications of water to a material’s surface all contribute to degradation in their own ways. This was recognized by Bill Lane, a member of the founding family of Atlas, through the works of Fred Stieg Jr., a paint and coatings researcher, that were published throughout the 1960’s. Stieg’s paper titled “Accelerating the Accelerated Weathering Test” from 1966 and his subsequent paper “The Dew Cycle Weather-Ometer® Re-evaluated - A Literature Review” in 1975 led to the development of the Atlas Dew Cycle Weather-Ometer®, a modified Sunshine Carbon Arc instrument with rack spray that was equipped with a chiller to enhance the formation of dew on the surface of samples under test.
