METHOD OF ACCELERATED AGEING TEST OF POLYMERIC MATERIAL Russian patent published in 2004 - IPC

Abstract RU 2243538 C2

FIELD: test engineering.

SUBSTANCE: invention refers to methods of testing of polymeric material to simultaneous thermal and UV-radiation influences. Samples of materials are subject to UV-radiation within 300-400 nm wavelength range. Radiation dose is 20-60 W·c/m² at temperature of 10-20 degrees C lower than temperature of at what structural transition of polymeric material starts and visual change in color characteristics is observed clearly.

EFFECT: reduced test time; improved efficiency of test method.
