Hydrocarbon Propellants in Self-Pressurized Containers
View through CrossRef
Abstract
A study was undertaken to determine whether the present official flammability tests for self-pressurized containers or aerosols are suitable for those containing hydrocarbon propellants. Fifty aerosols, five containing hydrocarbon propellants, were examined by the official methods for flammability (flame projection and flash point tests), and by other tests. Official tests detected the extremely flammable component in only one of the five highly flammable samples, a paint preparation. Of 24 samples examined for propellant identity, 5 contained hydrocarbon propellants, 10 contained hydrocarbon and fluorocarbon mixtures, and the remaining 9 contained fluorocarbons only. The present official flammability tests are not entirely suitable for self-pressurized containers with flammable propellants, and studies on flammable substances in pressurized containers should be continued.
