This European Standard specifies a method for the determination of the active content and molar mass of sodium dodecyl sulphate used as original titre for the titre determination of standard solutions for surface active agents titration.
NOTE These are used in the mixed indicator two-phase titration (e. g. ISO 2271) and in the potentiometric titration using a surface active agent sensitive electrode (e.g. EN 14480).
