To standardize the atmosphere (temperature and humidity) to which plastics are subjected before and during testing.

That night she dreamed in numbers: 23 ± 2°C, 50 ± 5% relative humidity, twelve hours, twenty-four hours — the standard’s rhythm. When she woke, she wrote them on index cards and pinned them above the bench like prayer flags. Practicality and reverence twined: she would run a series of validation runs to match these provisional conditions to her instruments. Unauthorized PDFs are often watermarked or missing pages

Conditioning at high humidity (e.g., ) to simulate tropical environments. Where to Find the ASTM D618-21 PDF

Details the required equipment:

One afternoon an inspector from the certification body arrived. Lina met him with a binder, not a PDF. Inside were the index cards, the validation runs, calibration certificates, and clear notes explaining the source of each assumption. She explained how she had derived the conditioning protocol, why each parameter mattered, and how her results proved consistency across repeated trials.

To comply with ASTM D618-21, laboratories must utilize specialized environmental chambers.
