ISO 14722 pdf download.Moped and moped-rider kinematics — Vocabulary 1 Scope 1.1 This International Standard defines terms, symbols and conventions related to moped and moped-rider motions and kinematics and to the modelling thereof. 1.2 It does not deal with methods of measurement, nor with the units used in reporting the results, nor with accuracy. 1.3 The definitions in this International Standard apply to two-wheeled mopeds as defined in ISO 3833. 1.4 This International Standard does not cover road mopeds which are controlled by a pedestrian or which are used for the carriage of goods to the exclusion of persons. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.
