ASTM D618 outlines the standard practices for conditioning plastics for testing. Why is this necessary? Plastic materials are hygroscopic (they absorb moisture from the air) and sensitive to temperature. A nylon part tested at 20% relative humidity (RH) will yield vastly different mechanical strength results than the same part tested at 80% RH.

is the current standard practice for conditioning plastics for testing , establishing uniform temperature and humidity protocols to ensure reliable data comparison across laboratories. Purpose and Significance The addition of "21" at the end often

The practice defines specific procedures for conditioning plastics, crucially noting that this is . While bringing a material to full equilibrium with its environment is the theoretical ideal, the standard acknowledges that for many plastics, achieving true equilibrium can take an impractical amount of time—sometimes up to 20 to 100 days or more depending on the material's thickness and history.
