A discussion of some concepts in thermal aging test-thermal aging and thermal breakdown

ICSD'98. Proceedings of the 1998 IEEE 6th International Conference on Conduction and Breakdown in Solid Dielectrics (Cat. No.98CH36132), 2002
Based on the experimental and analytical research results, the thermal stress preprocess and its performance in a thermal aging test should be divided into two distinct physical phases: thermal aging (TA) and thermal breakdown (TB). This paper presents firstly the definitions of TA, TB, and some related concepts in a thermal aging test for winding ...

Thermal aging of polychloroprene

Journal of Polymer Science, 1961
AbstractThe aging of polychloroprene has been studied at normal and elevated temperatures in air, in oxygen, and in nitrogen. A comparison of the molecular weight distribution curves for fresh specimens and for specimens aged under various conditions showed that on aging the polymer becomes heterogeneous.

Impact of Ageing on Thermal Efficiency of Solar Thermal Collectors

2008
Today it is common practice to calculate the performance of solar thermal systems or solar collectors based on the results of a thermal performance test carried out with a new solar collector. However, for an integral assessment of solar thermal collectors and systems, it is necessary to consider the change of performance with time due to degradation ...

Thermal ageing of cellulose paper insulation

1976 IEEE International Conference on Electrical Insulation, 1976
Results are presented of investigations into the thermal ageing behavior of cellulose paper insulation in which tests have been carried out between 100C and 160C on well-dried samples of cellulose paper contained in sealed glass vessels in an atmosphere of initially dry nitrogen gas.

Thermally-Induced Cutaneous Vasodilatation in Aging

Journal of Gerontology, 1993
A decrease in heat-induced cutaneous vasodilatation has been implicated as the cause of increased heat stress in the elderly. We used laser Doppler techniques to study the skin blood flow response to local heat in 82 healthy volunteers. There were 39 young volunteers, mean age 29 +/- 1, and 43 elderly volunteers, mean age 76 +/- 1.

Thermal stability of substitutional Ag in CdTe

Journal of Crystal Growth, 1996
The thermal stability of substitutional Ag in CdTe was deduced from lattice location measurements at different temperatures. Substitutional Ag probe atoms were generated via transmutation doping from radioactive Cd isotopes. The lattice sites of Ag isotopes were determined by measuring the channeling effects of emitted conversion electrons.

The effect of the thermal aging on polycarbonate

Materials Today: Proceedings, 2021
Abstract Polycarbonate (PC) is a widely used amorphous polymer. Among its many interesting properties, we can mention, among others, transparency, impact resistance and low density. However, long exposure to temperature changes its physicochemical, thermal and mechanical properties.
