Abstract

This paper presents experimental verification of the analytical results set forth in Part 1. It contains condensed descriptions of the experimental procedure, results, and conclusions. Four different tests were conducted. All of the tests involved observations of various exit signs by five volunteer observers. The signs involved were a radioactive isotope self-powered sign, an unlit electric sign, nd an energized electric sign. The general nature of the tests consisted of determining the maximum distance at which each observer could perceive, identify, and read the signs under various conditions of hallway illumination, electric sign brightness, and presence or absence of smoke. The tests confirm the theoretical predictions. Nevertheless there remain some difficult decisions relative to exit sign specifications, especially to provide for smoke conditions.
