It is annexed with the same document with edit/change marks so that the members can easily recognize how it was revised from the old document. The document was circulated among members of ISO/IEC JWG 11 in advance without document number. Now the document is in process of making French version to be forwarded as a bilingual document for consideration for FDIS circulation.

3 /FDIS ISO: 2000 iii INTERNATIONAL ORGANIZATION FOR STANDARDIZATION BASIC PRINCIPLES FOR GRAPHICAL SYMBOLS FOR USE ON EQUIPMENT Part 2: Form and use of arrows FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard ISO has been prepared by ISO technical committee 145: Graphical Symbols. The text of this standard is based on the following documents: FDIS TC 145 N xxx Report on voting TC 145 N yyy Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. In order to collect all requirements concerning relevant basic principles within one single numerical series, ISO technical committee 145: Graphical symbols and IEC technical committee 3 agreed to publish all parts of this International Standard within the series. The Technical Management Board of ISO and the Committee of Action of IEC have decided that, for each part of this series, one organisation shall be chosen responsible. The technical committees involved have agreed not to change any part of International Standard without mutual agreement.

4 /FDIS ISO: 2000 ii This publication has been drafted in accordance with the ISO/IEC Directives, Part 3. International Standard consists of the following parts, under the general title Basic principles for graphical symbols for use on equipment: Part 1: 200x, Part 2: 200x, Part 3: 200x, Part 4: 200x, Creation of graphical symbols (published by IEC) Form and use of arrows (published by ISO) Guidelines for the application of graphical symbols (published by IEC) Supplementary principles for the creation of graphical symbols for use on screen and displays (icons) (published by???) ISO replaces ISO It provides guidelines which are equally applicable to graphical symbols prepared within ISO and IEC.

5 /FDIS ISO: 2000 iii Introduction A graphical symbol is a visually perceptible figure used to transmit information independently of language. Graphical symbols are used on equipment for a wide range of purposes. For such symbols, consistency in the design of families of symbols used in one location or on similar equipment is an important issue, as is legibility when these symbols are reduced to small dimensions. Thus, there is a need to standardise the principles for creating graphical symbols for use on equipment to ensure visual clarity, to maintain consistency and thereby to improve recognition. This multi-part standard addresses the basic rules used to create graphical symbols for use on equipment, including line widths, form and use of arrows, negation elements, and use of the basic pattern which serves as a guideline for drawing equipment symbols. These design principles should be used for all graphical symbols for use on equipment: the standardised graphical symbols of which are found in ISO 7000 and IEC ISO has been produced to promote the use of a reduced number of arrow forms as symbol elements or graphical symbols.

6 /FDIS ISO: Scope International Standard series provides principles and guidelines for the creation and application of graphical symbols for use on equipment. This part of the standard lays down the basic principles and the proportions for arrows used to indicate various elements, forces, functions or dimensions. The arrows defined in this part of the standard are used as graphical symbols or graphical symbol elements. When new symbol originals are created or graphical symbols in current use are revised, the principles established in this part of ISO/IEC series are applied. 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 IEC and ISO maintain registers of currently valid International Standards.
