ActivePlastics—Phenol formaldehyde mouldings—Determination of free ammonia and ammonium compounds—Colorimetric comparison method
塑料 酚醛模塑制品 游离氨和铵化合物的测定 比色法
Application Summary AI generated
This standard specifies a colorimetric comparison method for determining the content of free ammonia and ammonium compounds in phenol-formaldehyde mouldings. It is applied in the quality control and testing of plastic materials, particularly for phenolic resin-based products used in electrical insulation, automotive components, and household appliances. The method helps manufacturers ensure product safety and performance by detecting potentially corrosive or odorous ammonia residues.
