ISO 4920
ISO 4920:2021 is an internationally recognized standard that specifies the spray rating test method used to determine the water repellency of textile fabrics, especially for those treated with water-resistant finishes. This test plays a crucial role in evaluating how effectively a fabric resists surface wetting by water. For businesses involved in textile production or product development, ISO 4920 is an essential quality assurance tool for meeting global performance expectations.
At Quality Asia Certification, we help organizations demonstrate product reliability and commitment to textile durability by evaluating and certifying products in accordance with ISO 4920:2021.

What is ISO 4920?
ISO 4920:2021 – Textiles — Determination of resistance to surface wetting (spray test) – is the latest version of the standard that provides a laboratory test method to measure the resistance of textile fabrics to surface wetting by water. It uses a specific apparatus that sprays water onto the fabric sample to assign a spray rating based on visible wetting.
This standard is applicable to all types of textiles, especially those used in:
- Outdoor garments
- Technical textiles
- Medical protective fabrics
- Military clothing
- Upholstery and furnishing materials
Why is ISO 4920 important?
In today’s competitive textile and apparel industry, demonstrating water-repellent properties is a key differentiator. ISO 4920:2021 certification not only confirms product quality but also ensures that your materials meet international benchmarks for water resistance.
Buyers, brands, and international markets increasingly demand certified data on textile performance. Having ISO 4920 certification boosts credibility, supports export compliance, and improves customer confidence in your product lines.
What are the benefits of ISO 4920?
- Verified Performance: Ensures that your fabrics meet specified water-repellent performance standards under controlled testing conditions.
- Updated Testing Parameters: Aligns with modern advancements in textile finishing, including newer nano-coating technologies and eco-friendly finishes.
- Widely Accepted: Recognized across global supply chains, including European, American, and Asian markets.
