Temperature at which an inflammable liquid produces a vapor which, when mixed with air, becomes an explosive mixture.
Industry:Construction
An extension of the sheet flooring up the wall a few inches to form a wall base integral with the flooring.
Industry:Construction
The propagation of a flame away from the source of ignition across the surface of a liquid or solid, or through the volume of a gaseous mixture.
'''Note:''' Most wood species are Class C Flame Spread unless the wood floor has been treated and marked.

Also called cratering, crawling, holes, spots or flow marks. When caused by surface contaminants the finish is applied over areas in which the wetting agents cannot perform their function. The finish then recedes away from this area reforming into the film. This "crawling" creates round or elliptical areas lacking adequate finish. May also be caused by failing to properly agitate a finish prior to application. Without proper agitation, properties within the finish may separate. The flattening and wetting agents will therefore not be in proper concentration and cause this appearance.

Resilient floor coverings are usually exempt from model building code flammability requirements. However, some building code officials, government agencies and other regulatory authorities require test information on the fire performance of resilient flooring. The most widely used test for flammability is based on the Flooring Radiant Panel Test. The current editions of the B.O.C.A., Standard Building Code, and the NFPA 101 Life Safety Code reference the Flooring Radiant Panel Test.
'''Note:''' Numerical flammability ratings alone may not define the performance of a product under actual fire conditions. Ratings are provided only for use in the selection of products to meet the specified limits. Flooring Radiant Panel Test - ASTM E 648 (NFPA Standard 253 and Federal Standard #372) - In this test, a horizontally mounted floor covering system is exposed to radiant energy from a gas/air fuel radiant panel mounted above one end of the sample and inclined at a 30 degree angle.
