Benzene is a solid below 42Â°F (5.6Â°C). DESCRIPTION: Benzene is used to make chemicals used in the manufacture of industrial products such as dyes, detergents, explosives, pesticides, synthetic rubber, plastics, and pharmaceuticals. Benzene is found in gasoline and trace amounts are found in cigarette smoke. Benzene has been banned as an ingredient in products intended for use in the home, including toys. Benzene has a sweet, aromatic, gasoline-like odor. Most individuals can begin to smell benzene in air at 1.5 to 4.7 ppm.
Hypervelocity refers to velocities in the range from a few kilometers per second to some tens of kilometers per second. This is especially relevant in the field of space exploration and military use of space, where hypervelocity impacts can result in anything from minor component degradation to the complete destruction of a spacecraft or missile.
Flash Point Determination. The flash point of a liquid is the lowest temperature at which sufficient vapor is evolved to form a flammable mixture in air at standard atmospheric pressure. The flash point provides a simple, convenient index for assessing the flammability of a wide variety of materials. Chilworth generally measures flash points in accordance with American Society for Testing and Materials (ASTM) Method D93-94 using the Pensky-Martens Closed Cup apparatus.
