Additional carbon based films are under development

specified in IEC 60404-8-4 and IEC 60404-8-7

This part of ISO 5630 specifies a method for accelerating the ageing of printing and writing papers through exposure to nitrogen dioxide gas and assessing the effect on mechanical and optical properties for the purpose of predicting stability to long-term natural ageing that occurs due to exposure to polluted air

— Conduct a gap analysis between the needs of the new charging policies and the existing standardized technologies for EFC
