The International Organization for Standardization (ISO) also offers relevant standards for assessing textile wetting properties. ISO 4920 is a water repellency test that can be used to evaluate how magnesium nitrate treatment affects the fabric's resistance to surface wetting. This test involves spraying water onto the fabric surface and assessing the degree of wetting visually.

For more specific evaluation of surface wettability, contact angle measurements are often employed. While not a standardized test method, the technique is widely accepted in the scientific community. It involves measuring the angle formed between a liquid droplet and the textile surface, providing quantitative data on the hydrophobicity or hydrophilicity of the treated fabric.

Performance testing also extends to durability aspects, as it is crucial to assess how long the modified wetting properties persist after repeated washing and wear. AATCC Test Method 61 simulates accelerated laundering conditions and can be used to evaluate the durability of the magnesium nitrate treatment. This test helps determine whether the modified wetting properties are maintained over the expected lifetime of the textile product.

In addition to these specific tests, broader performance standards such as those related to comfort and breathability should be considered. The use of magnesium nitrate to modify wetting properties may impact these characteristics, necessitating comprehensive testing to ensure that overall fabric performance is not compromised.
