Testing Standards for Home Furnishing Sponge Fillings
Mar 15, 2026| General Standards for Polyurethane Sponge
GB/T 10802-2006 - General Flexible Polyether Polyurethane Foams
Applicable to general-purpose flexible polyurethane sponges, this standard specifies the test methods and requirements for various parameters, including density, tensile strength, elongation at break, tear strength, compression set, resilience, and flame retardancy (where required).
QB/T 4463-2013 - Flexible Polyurethane Foam for Furniture
Specifically addressing foam materials used in furniture (such as sofas and mattresses), this standard emphasizes durability-specifically dynamic fatigue performance (stipulating a thickness loss rate of ≤ 25% after a specified number of compression cycles)-as well as environmental indicators such as formaldehyde emission levels (≤ 0.1 mg/m³) and heavy metal content.
Safety and Environmental Standards
GB 18580-2017: Indoor Decorating and Refurbishing Materials-Limit of Formaldehyde Emission from Man-made Boards and Their Products
If the sponge is intended for use in interior decoration, it must comply with a formaldehyde emission limit of ≤ 0.124 mg/m³ (determined via the 1 m³ climate chamber method).
Major International and Foreign Standards
ISO 845-2006: Cellular Plastics and Rubbers - Determination of Apparent Density
A globally recognized method for density testing, applicable to all types of sponges.
