Imaging materials. Processed vesicular photographic film. Specifications for stability1 Scope This International Standard establishes specifications for the stability of polyester base safety film which has a heat processed vesicular photographic image formed by nitrogen bubbles. It is applicable only to vesicular photographic film intended and used as LE 10 and LE 100 storage copies, which shall be stored in accordance with ISO 18902 and ISO 18911. This document characterizes only the inherent keeping behaviour of the film. However,

Photocatalysis is an advanced oxidation technology for the removal of persistent organic compounds and microorganisms from water and provides high-quality water purification
