Certified — and clear about what that means.
The rubber mulch we supply is third-party certified to the playground-safety standards that schools, parks, and inspectors look for. Here's what each one actually means, in plain English.
Every ounce we sell is IPEMA-certified and ASTM-tested.
The same certification covers every color and every pallet — the blue a daycare orders is tested to the identical standard as the black.
IPEMA Certified
IPEMA is the International Play Equipment Manufacturers Association. It runs an independent, third-party certification program. A manufacturer can't just claim a product is safe — an outside validator reviews the test data and confirms it meets the relevant ASTM standards before it earns the IPEMA seal.
The rubber mulch we supply for playground use carries IPEMA certification to the standards below. Look up any IPEMA-certified product below:

ASTM F1292 is the Standard Specification for Impact Attenuation of Surface Systems Under and Around Playground Equipment. In plain terms, it's the test that measures how well a surface cushions a fall.
A sample of the surface is tested by dropping a weighted instrumented headform onto it from increasing heights. The test measures the force of each impact and establishes a "critical fall height" — the maximum height from which a fall is cushioned within safe limits. A surface passes for a given playground only if its critical fall height meets or exceeds the height of the equipment kids can fall from.
The test measures two numbers, and both must pass: G-max (peak deceleration — under 200) and HIC, the Head Injury Criterion (under 1,000) — the same family of measurement used in automotive crash testing. The recycled-rubber nugget mulch we ship stays under both thresholds at the certified depths below, so you can match your equipment's fall height straight to a depth.
Certified depth by equipment fall heightUpdated July 2026
| Equipment fall height | Rubber mulch depth | Certified rating |
|---|---|---|
| Up to 10 ft | 4″ | Certified critical fall height: 10 ft |
| Up to 12 ft | 5″ | Certified critical fall height: 12 ft |
| Up to 16 ftCovers the tallest commercial play towers. | 6″ | Certified critical fall height: 16 ft |
| Home & backyard playsetsNot government-regulated. | 3–4″ | Standard residential recommendation |
Certified thickness-to-fall-height ratios for the IPEMA-certified recycled-rubber nugget mulch we ship, tested to ASTM F1292-22 and F3012-22 (listed in IPEMA’s public database). Public playgrounds follow the U.S. CPSC Public Playground Safety Handbook (Pub. 325); home playgrounds, its voluntary Home handbook (Pub. 324). Loose fill settles when rolled, so spread about an inch over the target depth. Figures reviewed July 2026.
ASTM F1951 — Accessibility, and the ADA
ASTM F1951 is the Standard Specification for Determination of Accessibility of Surface Systems Under and Around Playground Equipment. A public playground falls under the ADA, and F1951 is the test that says whether a surface lets a wheelchair travel across it.
Our nuggets are ASTM F1951-21 certified at two depths: 4 inches compacted to 3.5, and 7 inches compacted to 6.
Also tested: ASTM F3351 and ASTM D2859, the fire-test-response method for flooring materials.
ASTM F3012 — Loose-Fill Rubber Surfacing
ASTM F3012 is the Standard Specification for Loose-Fill Rubber for Use as a Playground Safety Surface Under and Around Playground Equipment. Where F1292 tests how a surface performs, F3012 specifies what the loose-fill rubber material itself must be — its consistency, particle characteristics, and the requirements to qualify as a certified playground surface.

Certified by IPEMA — listed in their public database.
Our rubber mulch is IPEMA-certified to ASTM F1292 and F3012. IPEMA is the independent body that certifies playground surfacing — an outside validator, not a self-declared label. Every certified product is listed in their public database at ipema.org.
For a school, park, or commercial order, ask us — we'll get you the specific certification documentation for the product on your order.
