A “wet out” can ruin your day. Under some circumstances, water-resistant apparel can protect your health and even save your life. Water resistance is the fabric’s resistance to water penetration in both rain and storm. It is often used in outerwear and heavy duty-use items, e.g. bags, tarpaulins and tents.
Nowadays, the water-resistant performance is a commonly used feature in outerwear and sportwear in the textile market.
How can you add value to your products by providing evidence of good water-resistant features?
Intertek Hong Kong supports water-resistant testing in both rain tests and hydrostatic pressure tests for clients with various requirements using different methods.

The Benefit You Should Know
As the US Customs uses the Rain Test to determine the import duty rate for coated fabrics, all manufacturers, suppliers and retailers can benefit from the lower duty rate if the product is proven to be water resistant using the rain test. This is good news for accessing the US market with a better-quality water-resistant or even waterproof product.
In general, waterproofing, water resistance and water repellency tests are usually carried out at the same time as breathability. Waterproof, water-resistant and water-repellent products may have a film or membrane as its watertight feature, which may affect the breathability. Therefore, these tests are usually bundled together for a comprehensive high-quality product.
