scope:
Specifies a method of chemically determining free formaldehyde in phenolic resins by potentiometric titration, in aqueous or organic solution. The method is applicable to resins with free formaldehyde contents up to and including 15 % m/m). For free formaldehyde contents between 15% m/m) and 30% m/m, it may be necessary to adjust the concentrations of the standard volumetric solutions used accordingly.
