Blog post — What ASTM D5705 Is and Why It Matters for Plastics Testing

ASTM D5705 is a standard test method that describes a procedure for determining the water absorption of plastics under specified conditions. For anyone working with polymer materials — product designers, materials engineers, quality managers, and manufacturers — understanding and using a reliable water‑absorption test like D5705 is important because moisture uptake can affect mechanical properties, dimensional stability, electrical behavior, and long‑term durability.

Requirements and Recommendations

The Apparatus

The core of the method involves a closed container, typically a glass jar or a specific test cylinder, equipped with a septum and a means to measure the vapor phase. astm d5705 pdf

The test is subjective—it relies on human sensory evaluation—but follows a strict protocol to ensure reproducibility across different laboratories.

Common Applications & Industry Requirements

1. Food Packaging

Major food brands (e.g., Nestlé, Unilever, PepsiCo) require their polyethylene suppliers to certify compliance with ASTM D5705. The specification often states: "Odor intensity shall not exceed 2.5 on a 1-6 scale when tested per ASTM D5705." Blog post — What ASTM D5705 Is and
