ASTM D3393 is the ASTM standard most closely associated with waterproofness requirements for coated fabrics, helping define how this material category is evaluated for water resistance. As the official Standard Specification for Coated Fabrics—Waterproofness, it supports consistent product expectations and clearer technical communication between suppliers, buyers, and test laboratories. For organizations working with coated textiles or similar protective materials, the standard can be an important reference for quality control and procurement decisions.

ASTM D3393 standard overview

The ASTM D3393 standard establishes a specification framework focused on waterproofness in coated fabrics. Based on its title, it is intended to guide how these materials are identified, described, or evaluated for their ability to resist water penetration. This makes the document useful when a coated fabric must meet a defined waterproof performance expectation rather than a general material description. ASTM D3393 helps align technical requirements with product selection, inspection, and acceptance processes.

Where is ASTM D3393 used?

ASTM D3393 is commonly used in settings where coated fabrics are selected for waterproof performance and must be specified with consistency. It is relevant in material sourcing, product qualification, and quality verification for coated textile goods that rely on water resistance. Because the standard centers on waterproofness, it is especially useful when comparing suppliers, confirming conformance, or documenting technical requirements for fabric-based products and assemblies.

Practical importance of ASTM D3393

In practice, ASTM D3393 helps reduce ambiguity around what it means for a coated fabric to be waterproof. That can support more reliable purchasing decisions, more consistent testing language, and better quality control across production and inspection workflows. Using a recognized ASTM specification also helps organizations document compliance expectations and manage product risk when waterproof performance is a key requirement.
