Scope
This standard specifies the methods for determining the formaldehyde content in surfactants and detergents using spectrophotometry and liquid chromatography. This standard is applicable to the determination of formaldehyde content in surfactants and detergents. The spectrophotometry method in this standard is suitable for determining the total formaldehyde (including formaldehyde release agents) in the sample, while the liquid chromatography method is suitable for determining the free formaldehyde content in the sample.
