If you’re adding artificial grass to a playground, making sure it meets ASTM F1951 standards is key to keeping the space accessible for everyone, including individuals using wheelchairs and other mobility devices. While artificial grass can be designed to meet these standards, the whole installation—including the base, infill, and transitions—needs to be done right to ensure compliance.
What is ASTM F1951 and Why Does It Matter?
ASTM F1951 measures how easy it is for wheelchairs to move across a surface. Just having ASTM F1951-certified artificial grass isn’t enough—the entire system, from the base to the edges, plays a role in making sure the surface is safe and accessible.
Key Factors for Compliance
1. Stability and Firmness
- The surface needs to be solid and supportive, so mobility devices don’t sink or get stuck.
- A well-compacted base and evenly applied infill help maintain stability over time.
2. Pile Height and Infill Choices
- Shorter pile heights (typically 1.25 inches or less) make it easier to move across the surface.
- Infills, such as sand or coated rubber granules, should be evenly spread to prevent uneven areas.
- If infill is too loose or deep, it can make movement difficult.
