    27、2017(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for w

    28、hich a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all

    29、 matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. Th

    30、is document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying an

    31、y or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www .iso .org/ patents).

This second edition cancels and replaces the first edition (ISO/TR 10064-1:1992), which has been technically revised. It also incorporates the Technical Corrigendum

    34、ISO/TR 10064-1:1992/Cor. 1:2006. The following changes have been made: the contents have been updated to correspond with ISO 1328-1:2013; additional material has been added on the proper setup and use of measuring machines, and how the measurement results can be used to determine the corrective step

    36、is document supplements ISO 1328-1:2013. It provides a code of practice dealing with measurements on flanks of individual cylindrical involute gears, i.e. with the measurement of pitch, profile, helix and tangential composite characteristics. It describes measuring equipment, provides advice for gea

    37、r measuring methods and for the analysis of measurement results, and discusses the interpretation of results. Measurements using a double flank tester are not included (see ISO/TR 10064-2). This document only applies to involute gears. 2 Normative references There are no normative references in this
