The literature on polyamides was reviewed to determine the nature and extent of information available on these materials which are commonly used in consumer and industrial applications. This review was limited to aliphatic polyamides normally called nylon
Two heat pump cycles operating with halogenated hydrocarbon mixtures are considered. Each Coefficient of Performance (COP) increases up to 50% under extreme temperature lifts when reciprocating compressors are employed. This is due to a reduction of the
The net production and destruction rates for acetylene, diacetylene, butadiene, and benzene have been determined from measurements of species concentration, temperature, and velocity in a methane/air diffusion flame. In addition, profile measurements of
The object of this study was to detennine if the use of a cycling controller would improve the efficiency of a residential air conditioner or heat pump. Cyclic tests were perfonned on a capillary tube heat pump in three configurations: as manufactured, as
A series of 60 fire tests have been conducted in an enclosure consisting of a corridor and three attached rooms, one of which served as a burn room. The purpose was to establish validation data for theoretical fire models of multi-room fire situations with
The literature on polyethylenes has been reviewed with an emphasis on the identification of gaseous products generated under various thermal decomposition conditions and the toxicity of those products. This review is limited to publications in English
The Veterans Administration (VA) has sponsored a project at the Center for Fire Research of the National Bureau of Standards to study smoke control in VA hospitals and evaluate design system approaches and methods of acceptance testing. This report
Methyl radicals have been detected in an atmospheric pressure, methane/air diffusion flame by three-photon ionization. The origin band of the transition between the X^2A2ground electronic state and the 3p2A2 Rydberg state is observed at 333.5 nm via two
A review of the literature was undertaken to ascertain the current knowledge of the nature of the thermal decomposition products generated from ABS and the toxicity of these evolved products intoto. The literature review encompasses English language
The literature on rigid polyurethane foam has been reviewed with an emphasis on the gaseous products generated under various thermal decomposition conditions and the toxicity of those products. This review is limited to publications in English through 1984
A systematic review is made of engineering data on the major aspects of upholstered furniture flammability: cigarette ignition, small open flame ignition, radiant ignition, transition from smoldering to flaming, flame spread rates, and heat release and
