This International Standard specifies two methods for the determination of the total chlorine content of unsaturated Polyesters and epoxide resins, namely : - method A : combustion in a bomb; - method B : combustion in a flask. NOTES 1 Determination of combined chlorine and bromine content or bromine content only, is also possible by these methods. The appropriate procedure shall be agreed upon by the purchaser and the supplier. 2 These methods are not applicable to the determination of total chlorine in epoxy resins containing chlorine as an impurity.
