Recommendations for the detection and estimation of nitrogenous treating agents in paper Ingestion-build-82061 — permeability of the aquiferWhat is BS 4497 Detection of nitrogenous treating agents in paper about? The most useful sorting test for nitrogenous treating agents is the dye staining test, although it does not give specific identification of melamine formaldehyde resin. The dye staining method is based on the fact that, although acid dyestuffs will not dye cellulose unless mordanted, they combine readily with proteins, such as casein and gelatin. BS 4497 provides guidance on the
