DIN 53495 Testing Plastics - Standard Test for Determining Water Absorption

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of DIN 53495 testing. This standard describes conventional methods for determining water absorption using the change in mass of plastic (excluding cellular materials 1) samples after conditioning in water.

The absorption of water can affect various properties of a plastic or a plastic component. In conjunction with other observations, the types of water absorption determined as specified in this standard can give an idea of ​​the behavior of plastics when affected by liquid or gaseous water.

This test method is for determining the amount of water absorbed by plastic specimens of defined sizes when immersed in water or exposed to moist air under controlled conditions. This test method is applicable to homogeneous materials and composites with reinforced polymer matrix tested below glass transition temperatures.

Alternatively, the water absorption of plastic samples of certain sizes exposed to immersion or moisture under controlled conditions is used to compare different batches of the same material or for quality control testing of a particular material. For this type of comparison, all test specimens should be as close as possible to the same dimensions and the same physical properties. Therefore, results from such tests are not used to compare the water absorption properties of different types of plastics. Simultaneous tests should be performed for more reliable results.
