Simply put, the water repellency test is like "simulating a light rain" to see whether the fabric or material surface can quickly shed water droplets rather than absorb them.

100 points (ISO Level 5): The surface remains completely dry, with water droplets rolling off entirely.

90 points (ISO Level 4): The surface shows slight dampness.

0 points (ISO Level 1): The surface is completely soaked.

Generally, achieving 90 points (ISO Level 4) or above is considered to meet the qualified standard for water repellency performance.

Performance indicators: They are important quality labels for outdoor clothing, footwear, headwear, bags, and other products.
