Better to spell out for clarity. 3 can be seen on drawing No. A system in place to ensure that quality of manufacture is produced and maintained; a system to prevent defective parts from being made, or, even if made, from getting into finished inventories. A prefix for standard hardware (catalog hardware) ID numbers. May be added to a drawing in a note form or inserted into the title block. The diameter is double the radius and is the longest possible chord you can draw in a circle. Features of size (FoSs) in reality always have actual sizes and forms that differ from their theoretical size and form; the purpose of tolerancing is to define whether the difference is acceptable or not. For example, ASME Y14.5 and Y14.100 are commonly used standards that define all of the symbols and drafting conventions used. See also. Symbol. A unit of measurement for pressure. An area of the drawing, almost always at the bottom right, that contains the title of the drawing and other key information.
