What safety standards govern flame resistance in plastic outdoor bar stools?

When selecting plastic outdoor bar stools, ensuring flame resistance is crucial for safety. Several international and regional standards regulate flame resistance in these products. Key standards include:

1. UL 94 (Underwriters Laboratories): A widely recognized standard for flammability of plastic materials, classifying materials based on their burning behavior.

2. ASTM E84 (Standard Test Method for Surface Burning Characteristics): Measures flame spread and smoke density for building materials, including outdoor furniture.

3. California Technical Bulletin 117 (CAL 117): A stringent flammability standard for upholstered furniture, often referenced for outdoor seating.

4. EN 13501-1 (European Standard): Evaluates fire performance of construction products, including plastics used in outdoor furniture.

Compliance with these standards ensures that plastic outdoor bar stools meet safety requirements, reducing fire hazards in commercial and residential settings. Always verify certifications when purchasing to guarantee flame-resistant properties.
