Abstract
Experiments were carried out at the University of Tokyo, Building Research Institute and Fire Prevention Board Laboratories in accordance with Japanese Industrial Standards and Fire Prevention Board Laboratory Standards on properties and flammability cotton broadcloth treated with various proprietary flame retarding chemicals as part of research on flame retardation of interior finishing materials in building work. Study of data from various measurements, testing methods and properties of chemicals used for treatment show that results of measurement obtained at the various testing institutions are much the same, that there is a need to unify testing methods and that there is no question about the various chemicals imparting flame retarding qualities, but there is a problem of durability against weathering, a property possessed by only one of the products.
