Scope

Scope: This document specifies the test method for formaldehyde emission from non-metallic materials in automotive interiors. This document is applicable to interior components of passenger cars and after-market interior decoration products. Main technical content: Weigh the samples on an analytical balance (accuracy: 1 mg) and add 50 mL of distilled water to each of six polyethylene bottles. After hanging five samples on hooks, tighten the containers and conduct a blank test with another container without hanging samples. Place the containers in a 60°C circulating air incubator, incubate for 3 hours, remove the containers, and let them stand at room temperature for 60 minutes. Then, remove the samples from the test bottles. To determine the formaldehyde content in the solution, use a pipette to take 10 mL of water-based solution from each of the six polyethylene bottles and place them in six 50 mL bottles. Add 10 mL of acetophenone solution and 10 mL of acetamide solution to each bottle. Shake the solutions well, heat them in a 40°C water bath for 15 minutes, and cool them in the dark to room temperature (about 1 hour). Adjust the wavelength of the spectrophotometer to 412 nm, and add distilled water and the measured solution to the cuvettes. Use distilled water as the reference to determine the absorbance of these six groups of solutions.
