Plastic Smoke Density Tester /ASTM E662/ ISO 5659.2
The Plastic Smoke Density Tester is a specialized instrument designed to evaluate the smoke generation characteristics of plastics during combustion. By measuring the specific optical density of smoke, the device provides the maximum specific optical density as the test result, which is crucial for assessing the smoke performance of plastics under controlled conditions. This information is vital for safety assessment, material selection, and compliance with international fire safety standards, particularly in applications where smoke toxicity and visibility are critical.
