Abstract:
A gasket according to the present invention is for sealing a valve or pipe used in a high-pressure gas supplying equipment, which is comprised of a polymer material containing magnetic particles. Also, in a determination method of deterioration and damages of a gasket according to the present invention, the aforementioned gasket is used as the gasket for sealing a valve or pipe in a high-pressure gas supplying equipment, and the magnetic force of the gasket is measured to determine the deterioration and the damages of the gasket.
