What are the fire rating certifications for marble outdoor trash cans?

When selecting marble outdoor trash cans for public or commercial spaces, understanding fire rating certifications is crucial for safety compliance. Marble, being a natural stone, is inherently non-combustible and typically achieves Class A fire ratings, but specific certifications verify this performance. The primary standard is ASTM E84, which measures surface burning characteristics, assessing flame spread and smoke density. Products with a low flame spread index (0-25) qualify as Class A, indicating high fire resistance. Additionally, certifications like UL (Underwriters Laboratories) or local building codes may require testing to ensure the trash cans do not contribute to fire propagation. For outdoor use, it's vital to confirm that the marble trash cans meet these standards, as they are often placed in high-risk areas. Always check for manufacturer documentation stating compliance with ASTM E84 or equivalent tests to ensure safety and regulatory adherence.
