Add, after the first paragraph: This Part 1 is intended to be used with a subsequent part that provides particular requirements based on the sensing technology. Where a part covering the sensing technology does not exist, this Part 1 can be used for guidance. Example: Part 1 and Part 2 are used for AOPDs, Part 1 and Part 3 are used for AOPDDRs. Add, before the last paragraph: This standard does not deal with requirements for ESPE functions not related to the protection of persons (e.g. using sensing unit data for navigation).
