The inner tank flame-retardant performance test for urban outdoor trash cans is a critical safety evaluation conducted under specific environmental conditions to ensure reliable fire resistance. According to standard testing protocols such as ASTM E84 and UL 94, the testing environment must maintain a stable temperature of 23°C ± 2°C and relative humidity of 50% ± 5% to eliminate external variables that could affect results. The test involves exposing the inner tank material to a controlled flame source for a designated period while measuring flame spread, smoke density, and after-flame time. Airflow within the test chamber must be minimized to prevent unnatural flame behavior, and all samples should be conditioned in the standardized environment for at least 24 hours prior to testing. These strict conditions ensure that municipal trash cans can effectively resist ignition from common urban fire hazards such as discarded cigarettes or small flammable materials, thereby enhancing public safety in cities worldwide.
