EN 50267-2-1 Halogen acid gas content test – Scope
EN 50267-2-1 Specifies the procedure for the determination of the amount of halogen acid gas, other than hydrofluoric acid, evolved during the combustion of compounds based on halogenated polymers, and compounds containing halogenated additives, taken from cable construction.
For reason of accuracy this method is not recommended for use where the amount of halogen acid evolved is less than 5mg/g of the sample taken. This method is not suitable for defining compounds or materials described as "zero-halogen" or "halogen-free". For such compounds or materials, and all compounds or materials contains less than 5mg/g halogen acid equivalent, it is recommended to use specified in EN50267-2-2.
