Chlorinated organic compoundsNot more than 0,06 % expressed as chloride, corresponding to 0,25 % expressed as monochlorobenzoic acid
Readily oxidisable substancesAdd 1,5 ml of sulphuric acid to 100 ml of water, heat to boiling point and add 0,1 N KMnO4 in drops, until the pink colour persists for 30 seconds.

Polycyclic acidsOn fractional acidification of a (neutralised) solution of calcium benzoate, the first precipitate must not be a different melting range from that of benzoic acid
Acidity or alkalinityNeutralisation of 1 g of calcium benzoate, in the presence of phenolphthalein, must not require more than 0,25 ml of 0,1 N NaOH or 0,1 N HCl
FluorideNot more than 10 mg/kg
ArsenicNot more than 3 mg/kg
LeadNot more than 2 mg/kg
MercuryNot more than 1 mg/kg
