Webinar recap: Why Test in Florida?

Outdoor weathering provides the most realistic way to evaluate how your materials perform in real-world environments. Because exposure conditions vary dramatically across the globe, selecting the ideal test site is critical to building an effective, reliable weathering program

In the first session of Q-Lab's Natural Outdoor Testing series, Q-Lab experts examined why South Florida has become a primary worldwide benchmark for outdoor weathering and how its climate can provide useful acceleration for materials used in temperate regions.

Why Florida?

Weathering is driven primarily by sunlight, temperature, and moisture. The balance of these factors varies from one climate to another, producing different material responses. Because testing every material in every global climate is impractical, industry leaders rely on proven benchmark locations. Florida has been the standard for outdoor testing since 1926 and remains embedded in countless international standards and specifications.

Florida and Temperate Climates

South Florida’s subtropical climate offers a powerful combination of environmental factors that directly apply to materials intended for temperate regions.

While temperate regions experience Florida-like weather during peak summer months, South Florida maintains those weathering conditions nearly year-round. In short: Florida delivers the same weather as much of the rest of the world, just more of it.

What Does Acceleration Mean?

The acceleration available in Florida depends on the climate to which it is being compared.

For example, if a temperate location experiences Florida-like conditions for four months of the year, the relationship between material response observed at the two sites could be 12 months divided by four months, which is three times the exposure rate. Actual acceleration will vary by location and material, but there are many reports of weathering rate being accelerated by two to four times when testing in Florida.

Laboratory Precision vs. Natural Realism

Faster test results are only valuable if they correlate to actual end-use performance. Pushing laboratory parameters beyond realistic limits can cause artificial material failures. Natural outdoor testing in Florida provides the crucial baseline needed to validate your laboratory accelerated test methods, ensuring your data is both fast and accurate.

Natural outdoor testing can therefore provide an important reference for laboratory accelerated testing.

Is Florida Right for Your Product?

Florida is not the appropriate exposure location for every application. Different climates produce different weathering conditions.

For hot, dry desert conditions, for example, Arizona may provide a more relevant exposure. Selecting the right location depends on the environment being simulated and the weathering factors that are most important to the product. Make sure to check out our webinar on Arizona testing as a complementary site for evaluating material performance in these climates.

Key Takeaways

The webinar highlighted several important points:

• Florida is a primary benchmark for outdoor weathering and has over a century of use in industry testing
• Sunlight, temperature, and moisture work together to produce material degradation
• Florida can provide natural acceleration for products intended to be used in temperate climates
• Acceleration depends on climate and location and should not be assumed to be the same for every product
• Outdoor and laboratory testing can complement each other, providing both realistic exposure and controlled test conditions
• The right exposure site depends on the intended environment and the type of weathering being evaluated

Frequently Asked Questions

Q: Why is Florida a benchmark for outdoor testing?

A: Florida has been a primary outdoor testing location since 1926 and is referenced by numerous industry standards and specifications.

Q: Why can Florida provide faster results?

A: South Florida experiences conditions similar to temperate summer weather for a greater portion of the year, providing more exposure to relevant weathering factors.

Q: Is Florida always two to four times faster?

A: No. Acceleration depends on how closely the comparison location matches Florida and how long similar conditions occur there.

Q: When should Arizona be considered?

A: Arizona is better suited to testing products where a hot, dry desert environment is more representative of the intended exposure.
