Scope
This standard specifies the method for determining the free formaldehyde content in household paper and paper products through water extraction and partial hydrolysis. This standard is applicable to the determination of formaldehyde content in household paper and paper products (tissue paper, toilet paper, wet wipes, diapers, sanitary napkins, etc.). The detection limit of the acetophenone spectrophotometry method in this standard is 10 mg/kg, and the detection limit of the high-performance liquid chromatography method is 6.0 mg/kg.
