6.6 The size of the fire safety signs shall be determined according to the maximum
viewing distance D. Determine the size of the sign according to Appendix A of GB
13495 after the required maximum viewing distance is measured.
The determination of the viewing distance D shall be in accordance with Appendix A
(informative) of this standard.
6.7 Displacement X of the sign shall be reduced as much as possible. For the
observer observing the maximum viewing distance D, the angle of displacement θ
should not be larger than 5° as a general rule, and shall not be larger than 15° for the
maximum extent. If the requirements cannot be met because of conditions, the size of
the sign shall be enlarged properly to meet the requirements of conspicuity.
