What fire resistance properties should composite material outdoor bar stools possess?

Composite material outdoor bar stools must possess specific fire resistance properties to ensure safety and durability in various environments. Key features include flame retardant additives that slow down combustion and prevent rapid fire spread. The material should meet industry safety standards, such as UL 94 or ASTM E84, which evaluate flammability and smoke production. Additionally, the composite should resist high temperatures without warping or releasing toxic fumes. Proper fire resistance not only enhances safety but also extends the stool's lifespan, making it ideal for commercial and residential outdoor use. Always verify certifications and material specifications before purchasing.
