ASTM D618-21 features four main conditioning methods, each designed for different situations:
– Subscription access for institutions.
Nylons (polyamides) absorb water, which acts as a plasticizer, decreasing tensile strength but increasing impact resistance. astm d618-21 pdf
ASTM D618-21 outlines that specimen conditioning is typically conducted for one of three primary reasons, as defined in section 4.1 of the standard:
The standard outlines specific procedures and conditions (Procedure A, B, C, etc.). 1. Standard Laboratory Atmosphere The primary standard laboratory atmosphere is defined as and relative humidity (RH) . 2. Conditioning Procedures Procedure A (Standard Conditioning): Conditioning at RH for a specified time (usually hours) to ensure moisture equilibrium. Procedure B (Dry Conditioning): Heating in an oven (e.g., ) to remove absorbed moisture.
is the definitive standard governing how plastic specimens are prepared, managed, and conditioned before undergoing testing. What are you evaluating
