Book excerpt: Excerpt from The Relative Safety of Brass, Copper, and Steel Gauzes in Miners' Flame Safety-Lamps Frequently the use of brass or copper as a gauze fabric for a flame lamp was advocated, and one company, thinking that the kind of material had no bearing on safety, substituted brass for steel in lamps stamped with the bureau's approval, without notifying the bureau of the change. The specifications relative to material and construction of gauzes were in the main based on European practice and investigations. The purpose of the investigation described in this paper was to conduct a limited number of check tests in order to determine to what extent European results Should apply to American types Of flame lamps, and consequently whether or not the Specifications of schedule 7 for gauzes required revision.
