Introduction
1. Background of standard formulation and analysis of technological evolution
GB/T 35239-2017 "Test Method for Removal Ability of Formaldehyde Removers for Artificial Boards and Their Products" was issued in 2017, mainly targeting the treatment of formaldehyde release from artificial boards and their products. With the improvement of environmental awareness and the country's emphasis on indoor air quality, this standard was formulated to regulate the test method of formaldehyde removers to ensure their effectiveness and consistency.

3. Implementation suggestions
Case analysis: Formaldehyde scavenger test of a furniture company
A furniture manufacturing company used a new formaldehyde scavenger in the production process and tested it according to GB/T 35239-2017. The results showed that the formaldehyde emission of the sprayed sample decreased by 85% within 24 hours, and the attenuation rate remained above 78% after 6 days, far exceeding the industry average.
Suggestions:
- Enterprises should establish a complete formaldehyde scavenger testing system
- Strictly prepare test pieces and control the environment in accordance with the standards
- Regularly test the attenuation rate to ensure long-term effectiveness
