ES 96100 is another engineering standard of the same Korean group, issued in a subject range distinct from that of the other requirement listed on this site, which indicates that the two documents address different parts of the vehicle rather than successive versions of one requirement. Reading the numbering system of a manufacturer is worthwhile for a supplier because it shows which documents were written to be read together: numbers issued in the same range generally treat one subject area, and the trailing digits identify the revision. As with the group's other standards, the document states the intermediate requirements that apply to a component while the brand's own component specification determines which of them are invoked for a particular part, so both should be obtained before a test plan is prepared.
