How do manufacturers test the resistance of the trash can to chemical degradation?

Manufacturers rigorously test the chemical resistance of trash cans to ensure they withstand exposure to harsh cleaning agents, environmental factors, and everyday wear. Here’s a breakdown of common testing methods:

1. Material Selection Analysis

High-density polyethylene (HDPE) and stainless steel are popular due to their inherent chemical resistance. Manufacturers evaluate material composition before production to predict performance.

2. Controlled Chemical Exposure

Samples are subjected to common chemicals (bleach, acids, solvents) in lab settings. The trash can’s surface is monitored for discoloration, warping, or weakening over time.

3. ASTM Standard Compliance

Tests often follow ASTM D543 for plastic durability or ASTM G31 for metal corrosion. These simulate long-term exposure to validate real-world usability.

4. Accelerated Aging Tests

UV and temperature-controlled chambers mimic years of use in weeks, checking for brittleness or structural breakdown when exposed to chemicals.

5. Field Testing

Prototypes are placed in high-traffic areas (hospitals, labs) to observe real-time degradation from cleaning routines and environmental stressors.

By combining these methods, manufacturers ensure trash cans remain durable, safe, and visually intact despite frequent chemical contact.
