At IPMA, our role is to provide meaningful, reliable certification for pickleball paddles intended for recreational play and unsanctioned competition. That means our testing standards must be stable, repeatable, and fair—especially for small and independent manufacturers.
At this time, IPMA is not testing or certifying foam core paddles. This decision is intentional, temporary, and rooted in technical and practical realities—not resistance to innovation.
1. Industry Testing Standards Are Still in Flux
Foam core paddles are a rapidly evolving category, and existing test protocols—particularly those being developed or modified by governing bodies—are still changing.
Certifying products against standards that are actively shifting creates confusion for manufacturers and players alike. IPMA believes certification should be based on settled, well-understood criteria, not moving targets.
2. Foam Is Inherently Unstable Over Time
Unlike traditional honeycomb or layered composite cores, foam materials are viscoelastic by nature. This means they are prone to:
- Compression set
- Softening with use
- Changes in rebound and feel over time
- Internal breakdown that may not be externally visible
Certification implies consistent performance, not just a one-time pass. At present, foam cores do not yet demonstrate the long-term stability required for responsible certification.
3. Wide Variability Across Foam Formulations
“Foam core” is not a single material category. Performance can vary dramatically based on:
- Density and cell structure
- Chemical formulation
- Manufacturing temperature and pressure
- Expansion and curing methods
Two paddles labeled as foam core can behave very differently, making standardized testing less meaningful until the category matures.
4. Failure Modes Are Often Hidden
Foam core failures tend to be internal and progressive, often going unnoticed until performance drops suddenly or structural failure occurs. This makes post-certification compliance and quality assurance far more difficult than with more established core architectures.
5. Current Testing Was Not Designed for Foam Behavior
Most paddle testing methods assume relatively elastic, predictable core behavior. Foam systems introduce damping and deformation characteristics that existing tests were not designed to measure accurately.
Proper foam testing would require purpose-built equipment and revised methodologies, not minor adjustments.
6. Cost and Access Matter
Developing and maintaining specialized foam testing equipment would significantly increase certification costs. IPMA exists to support small and independent manufacturers—not to create financial barriers that favor only large brands with deep R&D budgets.
7. Certification Should Follow Innovation—Not Chase It
Innovation thrives in experimental and recreational spaces. Certification, however, should come later—after performance characteristics, durability, and safety are well understood.
Choosing not to certify too early is a form of responsible restraint, not opposition.
Our Position Going Forward
IPMA’s decision is not a permanent one. As foam core technology stabilizes, testing standards mature, and reliable methods become available, we are open to revisiting foam paddle certification.
Until then, our focus remains on providing clear, fair, and credible certification for paddle technologies that are proven, stable, and appropriate for the players and manufacturers we serve.
