Persian cat since the early 1990s and the Persian lost its top spot to the British Shorthair in 2001. As of 2012, it was the 6th most popular breed, behind the British Shorthair, Ragdoll, Siamese, Maine Coon and Burmese. In France, the Persian is the only breed whose registration declined between 2003 and 2007, dropping by more than a quarter. The most color popular varieties according to CFA registration data are seal point, blue point, flame point and tortie point Himalayan, followed by black-white, shaded silvers and calico. The breed standards of various cat fancier organizations may treat the Himalayan and Exotic
Flash point liquid, and equilibrial, such as Small Scale (commonly known as Setaflash), where the vapours are deemed to be in temperature equilibrium with the liquid. In both these types, the cups are sealed with a lid through which the ignition source can be introduced. Closed cup testers normally give lower values for the flash point than open cup (typically lower) and are a better approximation to the temperature at which the vapour pressure reaches the lower flammable limit. The flash point is an empirical measurement rather than a fundamental physical parameter. The measured value will vary with equipment and test protocol
