BS 3641 is a British standard that discusses the symbols for machine tools. BS 3641-1 is the first part of the multi-part series that outlines the basic designs for symbols intended for use on machine tools.
Drawings in BS 3641-1 relate to the form of symbols only and are not absolute dimensional representations.
BS 3641-1 makes recommendations for proportions to be used in the design of symbols, independent of actual dimensions.
BS 3641-1 also provides for the grouping together of symbols selected from the same or different sections of the standard according to individual requirements.
BS 3641-1 on general symbols for machine tools is useful for:
General symbols are the basis of all human understanding and serve as vehicles of conception for all human knowledge. Symbols facilitate understanding of the world in which we live and thus serve as the ground upon which we make judgments.
BS 3641-1 assist you with sizes, proportions, the use of the arrow, directional information arrows, relative motion information, dimension arrows, functional arrows, and the grouping of symbols to ensure proper understanding of symbols and prevent misinterpretations between entities in the industry.
In compliance with BS 3641-1, you can uniform the vocabulary related to symbols for machine tools for risk/hazard mitigation.
