ISO 7816 consist of 6 parts and was originally developed for contact type
ISO 7816-1 Physical characteristics
ISO 7816-2 Dimensions and location of the contacts
ISO 7816-3 Electronic signals and transmission protocols
ISO 7816-4 Organization, security and commands for interchange.
ISO 7816-5 Number system and registration procedure for application identifiers
ISO 7816-6 Interindustry data elements
The e-passport uses elements of ISO 7816-4
