ASTM D618-21 defines the procedures for conditioning plastic specimens to bring them into equilibrium with "normal" room conditions, ensure reproducibility, or simulate abnormal conditions to predict service performance. It is essential for eliminating the variable effects of previous exposure to humidity and temperature.

Once you have the , reading it is not enough. Here is a practical checklist for implementation: astm d618-21 pdf

Plastics are hygroscopic (they absorb moisture from the air) and thermally sensitive. The physical properties of polymers—such as tensile strength, impact resistance, and electrical conductivity—can fluctuate significantly based on: ASTM D618-21 defines the procedures for conditioning plastic

The ASTM D618-21 document outlines specific procedures, times, and tolerances. It establishes a baseline environmental history for all plastic test specimens. 1. Standard Laboratory Atmosphere astm d618-21 pdf
