How do manufacturers test the fade resistance of logos on outdoor trash cans?

Manufacturers employ rigorous testing protocols to ensure logos on outdoor trash cans maintain their visual appeal and branding integrity despite constant exposure to harsh environmental elements. The primary method involves accelerated weathering testing, where samples are placed in specialized chambers that simulate years of sun exposure, rain, and temperature fluctuations in a condensed timeframe. These chambers use powerful xenon-arc lamps that replicate full-spectrum sunlight, including damaging UV rays which are the primary cause of color fading.

Additionally, manufacturers conduct specific UV exposure tests that focus exclusively on ultraviolet light degradation. Samples undergo precise color measurement using spectrophotometers before and after testing to quantify color change in numerical values (Delta E values). This data-driven approach allows for objective assessment of fade resistance rather than relying on subjective visual inspection alone.

Real-world testing is equally crucial, with manufacturers placing trash cans in various geographic locations with different climate conditions – from intense desert sun to coastal salt environments. These field tests provide valuable long-term data that complements laboratory results. The combination of accelerated laboratory testing and real-world exposure ensures that logos on outdoor trash cans maintain their color integrity and legibility for years, preserving brand identity in public spaces.
