Moisture Absorption Properties

Test Methodology

Test is prepared in reference to ISO 62:2008 Plastics - Determination of water absorption

Preparation

Three specimens are printed in each material:

• 2 rods 26mm in diameter and 25mm in length printed vertically and horizontally

• 100mmx100mm plate 2mm thick printed flat

Conditioning

Before testing, the specimens are allowed to cool to room temperature in a sealed container filled with desiccant maintaining a RH of <10% for 24h.

Initial Recording

The specimens are each weighed on a scale, recorded as m1. The lengths of the rods are recorded as l1.

Immersion

The specimens are completely immersed in room temperature tap water for 24 hours, taking care to separate the parts to prevent them from contacting each other.

Second Recording

The specimens are lightly dried with a cloth to remove any surface moisture, and weighed as m2. The lengths of the rods are recorded as l2.
