TS ISO 9959-1

TS ISO 9959-1 defines a drawing test used to evaluate the performance of numerically controlled vector plotters. The standard focuses on graphical quality capabilities in a machine-type-independent way, with particular attention to dynamic accuracy and the time required to complete a drawing. In practical terms, it is concerned with how the plotter behaves while producing line work, not merely whether it can reach a position.

In general technical terms, vector plotters are electromechanical devices that create images by moving a pen or drawing tool along controlled axes. Their output quality depends on motion control, acceleration, direction changes, positioning stability, and the interaction between the control system and the marking tool. Dynamic accuracy describes how faithfully the machine follows the intended path during movement, while drawing time provides a useful indication of productivity and the system’s response to more complex graphics.

What the test covers and what it does not

The scope explicitly excludes evaluation of static drawing accuracy, which is normally assessed at the place where the drawing is made. This distinction matters because the drawing medium can change dimension under different climatic conditions, and such changes can affect results. The standard therefore addresses comparative performance of the machine in a drawing test environment rather than absolute geometric accuracy on a finished drawing.

• Applies to vector plotters, described here as electromechanical plotters.
• Addresses graphical quality capabilities, especially dynamic accuracy and required drawing time.
• Defines a drawing test that is independent of the machine type.
• Does not cover static drawing accuracy influenced by climatic changes in the drawing medium.
