Medical Laboratory Testing: Compression
Compression testing measures how foams, cushions, and elastomeric materials respond to compressive loads, including deflection, compression set, and recovery. The test applies controlled force and evaluates support characteristics and resilience after loading. For medical manufacturers, compression properties are essential for mattresses, OR pads, wheelchair cushions, and positioning aids to provide proper pressure redistribution and patient comfort while preventing pressure injuries.
Proper compression performance helps distribute pressure evenly and allows materials to recover shape after use. In healthcare, this reduces the risk of pressure ulcers and improves patient outcomes. Applus+ Reliable Analysis already maintains accredited compression and foam testing capabilities, integrated with our load deflection, resilience, and durability programs.
These evaluations support key standards for hospital mattresses and pressure-relief surfaces. Manufacturers use compression data to qualify foams that deliver consistent support and long-term performance. Applus+ Reliable Analysis delivers consistent, reproducible results using equipment already operating daily under our ISO/IEC 17025 accreditation.
Common Compression Medical Testing Standards
ASTM D3574 Flexible Cellular Materials Slab, Bonded, and Molded Urethane Foams
ASTM D3574 includes multiple procedures for evaluating compression properties of flexible cellular urethane foams, such as compression force deflection, compression set, and recovery after compression. The standard provides standardized methods for measuring how foams respond to compressive loads. It is essential for medical mattresses, OR pads, wheelchair cushions, and positioning aids to ensure proper support, pressure redistribution, and recovery characteristics that help prevent pressure injuries.
ISO 3386-1 Flexible Cellular Polymeric Materials Low-Density Materials
ISO 3386-1 determines the stress-strain characteristics of low-density flexible cellular polymeric materials under compression. The standard measures the force required to achieve specified compression percentages and evaluates recovery. It is particularly relevant for medical foams and cushions used in patient positioning and pressure-relief applications to characterize their support and comfort properties.
ASTM F1566 Hospital Mattresses Compression Requirements
ASTM F1566 specifies performance requirements for hospital mattresses, including compression and firmness characteristics that affect pressure redistribution. The standard includes tests for compression deflection and durability under repeated loading. It serves as the primary reference for medical mattresses, OR table pads, and pressure-relief surfaces designed to reduce the risk of pressure ulcers in clinical settings.
ISO 10993-18 Biological Evaluation of Medical Devices
ISO 10993-18 includes compression testing as a conditioning step to evaluate how mechanical compression affects material properties and extractables. The standard helps assess potential changes in foams and cushions used in patient-contact applications. It is critical for ensuring that compressive forces do not lead to degradation or increased leachables in long-term use devices.
ASTM D3575 Flexible Cellular Materials Made From Olefin Polymers
ASTM D3575 evaluates compression properties of flexible cellular materials made from olefin polymers, including compression set and deflection characteristics. The standard provides methods for assessing how these foams respond to compressive loads and recover. It is valuable for medical padding, cushions, and components where olefin-based foams are used for their durability and resilience under repeated compression.
