Conditioning fails most often when a technician removes a specimen from a 23°C chamber and carries it across a 35°C factory floor. The standard requires testing immediately or within a specified "grace period" (typically 1 minute for critical properties). Common Misconceptions About D618-21 Myth 1: "It only applies to mechanical testing." False. ASTM D618-21 explicitly covers electrical, optical, and even thermal testing. Scribd, Academia

A: Your test results are invalid per Section 4 of the standard. Recondition and retest after recalibration.
