Polymers have low thermal conductivity. It takes time for the core of a thick plastic specimen to match the temperature of the testing room.
: If a specific material specification (e.g., from ASTM D4000) exists, it takes precedence over D618.
However, just as they thought they had solved the problem, they received another call from the production manager. This time, it was about a different product, a batch of PVC sheets that were reported to have excessive shrinkage. At its core, this standard defines two things:
: Subjecting specimens to extreme temperature or humidity to simulate real-world service environments. Key Conditioning Procedures
Outlines how to handle samples prior to the conditioning phase.
When compiling data sheets or academic papers, referencing the conditioning method precisely is vital for reproducibility. A standard conditioning note in a report typically uses a specific shorthand format: Alternatively, would you like a listed in the standard
Authorized resellers such as IHS Markit (S&P Global), Techstreet, or ANSI store also provide legal PDF downloads of the standard. Keeping Up with Revisions
The most common environment defined in ASTM D618-21 is the "Standard Laboratory Atmosphere." Unless otherwise specified, the parameters are: 23°C (73.4°F) Relative Humidity: 50% Tolerances: ±2°C and ±10% humidity for general use.
24 hours immersion in distilled water at 23°C. Critical for water-absorbent materials like Nylon (PA6/66).
