This standard specifies a standard method for determining the chlorine content in vinyl chloride homopolymers and copolymers without plasticizers and additives. It provides two main methods: Method A (Combustion Bomb Method) and Method B (Combustion Flask Method). Both methods involve the oxidative decomposition of the sample, converting organic chlorine into inorganic chloride ions, followed by titration using a potentiometric titrator or a standard silver nitrate solution. The chlorine content is determined by measuring the abrupt change in potential or the formation of a precipitate.
