The test should be conducted on a window of the maximum
size (in terms of both the height and the width) and the type of the
glass pane and/or the minimum thickness of the glass pane or panes
and gaps, if appropriate, for which approval is sought. Test results
obtained on this configuration should, by analogy, allow approval
of windows of the same type, with lesser dimensions in terms of the
height and width and with the same or greater thickness.
