/0/0 DELOYMENT IN STANDARIZATION Why do we need new ISO-Standards for RPD? because there are no International Standards for RPD existing worldwide because there is a need to define and establish equal protection levels for wearers in any workplace regardless of world s location because gaps of existing standards have to be closed The protection of the wearers is in the focus of ISO RPD and that is called: Human Factors driven standardization! Why does the world need new ISO-Standards? because ISO Standards have a good chance to remove barriers to world trade! I S O R P D for a better protection
