Test method is applied for structural core materials such as honeycomb or foam and covers the determination of water absorption when immersed or in high relative humidity environments. ASTM C outlines three methods: At least five 3. The specimens are then dried, removed from the drying oven, and allowed to cool in a desiccator. The specimens are then weighed on an analytical balance to the nearest xstm. The specimens are then immersed in deionized water or placed in the appropriate conditioning environment.
The specimens are removed from the conditioning environment after 24 hours, 48 hours, or after thirty days, depending on c227 required conditioning. The increase in mass is calculated as follows: Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
