DIN EN ISO 20863 Footwear Water absorption and desorption test
The DIN EN ISO 20863 standard is designed to evaluate the water resistance, repellency, and absorbency properties of footwear. This crucial test assesses how effectively a shoe or boot can withstand moisture penetration while also measuring its ability to retain moisture within its structure. The test is particularly important for footwear manufacturers who aim to ensure their products meet international standards and consumer expectations regarding durability and comfort.
The primary focus of this standard lies in determining the water absorption capacity as well as the rate at which water can be removed from the material after immersion. This helps in understanding how the footwear behaves under varying conditions, such as during heavy rainfall or prolonged exposure to humid environments. The test provides a scientific basis for comparing different materials and designs, aiding quality assurance processes.
The methodology involves immersing footwear samples in water at specific temperatures (typically 23°C) for predetermined durations. After soaking, the samples are removed from the water bath and allowed to dry according to prescribed protocols. During this drying process, the amount of absorbed water is measured periodically until it reaches an equilibrium state.
Understanding these parameters is essential for several reasons. For instance, they influence not only the comfort level experienced by users but also the longevity of the product itself. Moisture retention can lead to discomfort due to perspiration accumulation inside the footwear, whereas excessive water absorption without proper desorption could compromise the structural integrity over time.
The importance of this test extends beyond just compliance with regulations; it plays a vital role in enhancing customer satisfaction by ensuring products perform well across diverse climatic conditions. By adhering strictly to international standards like DIN EN ISO 20863, manufacturers can gain competitive advantages while maintaining high-quality benchmarks.
| Test Parameter | Description |
|---|---|
| Water Absorption Capacity | The quantity of water that can be absorbed by the material without causing damage. |
| Desorption Rate | The speed at which moisture is released from the material post-absorption. |
Scope and Methodology
This section outlines the detailed procedures involved in conducting the DIN EN ISO 20863 test for footwear water absorption and desorption. The scope encompasses all aspects from sample preparation to final measurement.
- Sample Preparation: Samples must be cut into standardized shapes and sizes, ensuring homogeneity across samples within a batch.
- Immersion: Specimens are placed in a water bath maintained at 23°C ± 1°C for the specified duration.
- Drying Process: After soaking, samples undergo controlled drying to observe changes in mass over time.
| Test Step | Details |
|---|---|
| Initial Measurement | Determine the mass of each specimen before immersion. |
| Post-Immersion Mass | Measure the wet mass after exposure to water for the required time. |
