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.
