Analysis of ASTM D 1037 accelerated-aging test
The ASTM D 1037 six-cycle accelerated-aging test for wood-based panel products was analyzed to determine how each successive aging cycle and selected steps in each cycle contribute to panel deterioration. Hardboard, particleboard, flakeboard, waferboard, and oriented strandboard were evaluated. The rate of panel deterioration generally decreased with each successive aging cycle. Four cycles of ...
متن کاملAccelerated Heat Aging Study of Phenolic/Basalt Fiber Reinforced Composites
One of the greatest impediments to use polymer-matrix composites is their susceptibility to degradation when exposed to the elevated temperatures and the limited knowledge on the thermal and mechanical properties of these composites at such temperatures. The objective of this study is to evaluate the effects of accelerated heat aging on the tensile properties of the Woven Basalt/Phenolic (WBP) ...
متن کاملEvaluation of the effect of maternal Soybean (Glycine max) nutrition on seed quality traits under accelerated aging test
Extended Abstract Introduction: Structural and physiological delicacy of soybean seeds is known as an important quality indicator in the cultivation of this plant, but at the same time, the most chronic problems of soybean seed quality are the reduction of seed quality during storage and before sowing. The effect of some nutrients on the quality of soybean seeds under accelerated aging stress ...
متن کاملPTSD and Accelerated Aging
For hundreds of years, scientists have recognized that the human body is highly sensitive to the external environment. In the mid-1800s, Claude Bernard, who is credited with being among the first to develop and apply scientific methods of experimentation to the study of physiology, suggested that the external environment could alter the “milieu intérieur” (interior environment; Bernard, 1974), ...
متن کاملAccelerated Aging Test Methods for Predicting the Long Term Thermal Resistance of Closed-Cell Foam Insulation
The accurate estimation of the thermal performance of insulation products used in buildings over their expected lifetime has been a recognized challenge for over 25 years. This is because the lifetime of such products is long, thermal aging is caused by the diffusion of a multitude of gases, and the insulation product is not homogeneous. The task of developing a standard test method for predict...
