ASTM D3574 is a testing standard developed by ASTM International (formerly the American Society for Testing and Materials). It specifies procedures for measuring the properties of flexible cellular materials, commonly polyurethane foam. These foams are widely used in applications such as cushions, mattresses, automotive interiors, and packaging.
The standard ensures consistent, reliable methods for assessing characteristics like indentation force deflection (IFD), tensile strength, elongation, and tear resistance. By following ASTM D3574, manufacturers can maintain product quality and meet industry specifications.
The standard includes a series of test methods, each focusing on a specific property of foam materials:
Density (Test A) – Determines the weight of the foam per unit volume, which impacts firmness and comfort.
Indentation Force Deflection (Test B) – Measures how much force is required to compress the foam by a certain percentage, indicating softness or firmness.
Compression Set (Test D) – Evaluates the foam’s ability to return to its original shape after being compressed for a set period.
Tensile Strength and Elongation (Test E) – Tests the foam’s ability to stretch and resist breaking.
Tear Resistance (Test F) – Measures how well the foam resists tearing under stress.
For manufacturers and suppliers, compliance with ASTM D3574 means:
Consistent product performance
Reduced risk of failure in real-world applications
Improved customer satisfaction and trust
Meeting OEM and industry requirements for quality assurance
Products that undergo ASTM D3574 testing are more likely to withstand everyday use and environmental stress, making this standard critical in the quality control process.
You’ll find ASTM D3574 testing applied in industries such as:
Automotive – Seats, headrests, and interior padding
Furniture – Cushions, sofas, and chairs
Bedding – Mattresses and mattress toppers
Packaging – Protective foam for delicate products

1. What is ASTM D3574?
ASTM D3574 is a standard test method for flexible cellular materials, primarily polyurethane foams. It measures properties such as indentation force deflection (IFD), compression set, and durability.
2. Why is ASTM D3574 important?
This standard ensures consistent quality and performance in foam products used for furniture, bedding, automotive seating, and other applications. It verifies comfort, resilience, and long-term durability.
3. What properties does ASTM D3574 measure?
Key properties include density, indentation force deflection (hardness), compression set, tensile strength, tear resistance, fatigue durability, and resiliency.
4. Who needs ASTM D3574 testing?
Manufacturers of foam products, automotive suppliers, furniture makers, and bedding companies often require this testing to meet industry standards and customer expectations.
5. Does ASTM D3574 apply to all foams?
It mainly applies to flexible polyurethane foam and similar cellular materials, not rigid foams or other unrelated polymers.
6. How long does ASTM D3574 testing take?
The time frame depends on the specific tests requested. Some tests can be completed within days, while fatigue or durability tests may take longer.
7. Is ASTM D3574 required for compliance?
It’s not always mandated by law, but many industries and customers require it as a benchmark for quality assurance.
