If the pattern under [§ 157.100(a)(4)](/cfr/33/157.100.md?p=a-4) or [§ 157.102(d)](/cfr/33/157.102.md?p=d) cannot be shown on a plan, a scale model of each tank must be built for Coast Guard inspection to simulate, by a pinpoint of light, the projected direct impingement pattern on the surfaces of the tank.
