ISO Foreword
[International Organization for Standardization] is an industry-wide association established to promote the development of international standards (ISO member bodies). The work of formulating international standards is carried out by the technical committees of ISO. If a member body has already established a standard for a certain technical requirement, it has the right to participate in the work of the committee. International organizations that maintain contact with ISO departments, government and non-governmental organizations may also participate in related work. In the field of electronic technical standards, ISO maintains a close cooperative relationship with the International Committee for Standardization (IEC). The international standard proposals that have been formally approved by the technical committee are submitted to the member bodies for presentation. The international standard can only be published after obtaining the approval of at least 75 members of the voting bodies. TS07072 is a national standard. 1S47C72:133.1 (first edition replaces 1S07072:1982 first edition) is prepared by the Technical Committee for Working Devices at the meeting of the Technical Committee for Forestry and Foreslry Machinery. This edition adds some requirements for locking frequency and driving comfort in addition to the size of the elastic pin.
