EN ISO 24232:2025 (often written as EN24232:2025) has officially replaced EN 343:2019.

1、 Alternative relationship

New standard: EN ISO 24232:2025 (Protective clothing - Rain proof, equivalent to ISO 24232:2024).

Old standard: EN 343:2019 (Protective clothing - Rain proof).

Effective/Alternative Time: CEN was approved on October 17, 2024, and officially released in October 2025 to replace EN 343:2019; After various countries converted to national standards, they gradually abolished the old versions (such as Spain 2026-02-01).

Status: EN 343:2019 has been revoked, and the new certification should be based on EN ISO 24232:2025.

2、 Core changes (key points)

Standard number upgrade: from EN 343 to EN ISO 24232, becoming an ISO international standard (no longer just a European standard).

Scope of application: Covering rain, snow, fog, and ground moisture, consistent with the old version.

Grading system: retaining the dual levels of waterproof (WP) and breathable (Ret) (grades 1-3), but aligning the testing methods and limits with ISO, with more rigorous technical details.

DROTEX's quality control of flame retardant fabrics begins with stringent standards at the source. High-speed flame singeing technology precisely and instantly burns the fabric fibers at high temperatures.

Pre-treatment meticulously removes impurities and deeply optimizes the basic properties of the fibers; mercerizing revitalizes the fabric's luster and enhances wearing comfort, with each step adhering to stringent industry standards. The dyeing process strictly controls evenness and colorfastness, ensuring long-lasting, stable colors that are resistant to fading; core flame-retardant processes strictly adhere to both national and international standards, building a solid safety foundation.

Ultra-softening treatment delicately enhances the skin feel, achieving a balance between powerful flame retardancy and a gentle, skin-friendly experience; the stretching process precisely controls tension, ensuring uniform and consistent width; the pre-shrinking process stabilizes the finished product dimensions while optimizing the feel and subsequent processing precision.

Quality inspectors are present throughout the entire production process, strictly adhering to the US standard four-point system for real-time on-site sampling inspections. Each process is rigorously controlled, with meticulous craftsmanship ensuring the core quality of DROTEX's special FR fabrics.
