ISO 3952-1:1981/Amd 1:2002 is an international standard that specifies the recommended proportions for graphical symbols used in technical product documentation, specifically within kinematic diagrams. It provides guidelines for the dimensions of these symbols based on the line width and lettering heights, as mentioned in ISO 7083:2021. The amendment (Amd 1:2002) likely clarifies or expands upon the original standard, possibly by adding new symbols or refining existing ones.
