Rizhao Dongsheng Carpet Co., Ltd. has completed European reaction-to-fire testing on a submitted printed tufted carpet sample. According to test report SHFTS26000750R01_EN, issued by SGS-CSTC Standards Technical Services (Shanghai) Co., Ltd. on July 20, 2026, the sample was classified Bfl-s1 in accordance with EN 13501-1:2018. The result supports a practical idea that matters to today's commercial interiors: strong visual design and clearly documented fire-performance data can be developed together rather than treated as competing priorities.

TEST SNAPSHOT Classification Bfl-s1 under EN 13501-1:2018 Critical heat flux 8.9 kW/m² Smoke result158 %·min Small-flame test 15 s exposure; Fs ≤ 150 mm within 20 s |
The assessment combined two test methods used for flooring products. EN ISO 9239-1:2025 evaluates burning behavior using a radiant heat source, while EN ISO 11925-2:2026 evaluates ignitability when a product is exposed to a small, directly applied flame. Together, these methods provide evidence for classification within the European reaction-to-fire system for flooring.
The report records a critical heat flux of 8.9 kW/m² and a smoke result of 158 %·min. During the single-flame-source test, with a 15-second exposure, the flame front did not exceed 150 mm within 20 seconds. Under the classification criteria reproduced in the report, Bfl requires a critical heat flux of at least 8.0 kW/m² together with the specified small-flame performance, while the s1 additional classification applies when the smoke result is no more than 750 %·min. On that basis, the submitted sample received the combined classification Bfl-s1.
The letters and numbers have an important, specific meaning. Bfl indicates a comparatively high reaction-to-fire class for flooring products within the EN 13501-1 system. The suffix s1 identifies the lower-smoke category used for flooring in this classification framework. It should not be interpreted as a claim that the carpet is non-combustible, fireproof, or suitable for every building without further review. Instead, it provides architects, interior designers, contractors, distributors and project owners with a standardized way to compare performance under defined laboratory conditions.
For specification teams, the most useful next step is to connect the classification to the exact product and proposed build-up. Buyers should request the current report, compare the sample description and thickness with the offered construction, and confirm the substrate, fixing method and joint condition before approval. Design samples, production samples and final supply should remain traceable to the same controlled specification. This disciplined process is especially important when colors, yarn systems, backing components or installation details are customized for a project. It helps preserve the value of the test evidence while allowing designers to explore scale and color with confidence. Clear technical documentation also makes tender review, submittal preparation and communication with local consultants more efficient.
For Rizhao Dongsheng Carpet, the Bfl-s1 result reflects an ongoing focus on transparent performance information for international projects. We will continue connecting original surface design, controlled manufacturing and verifiable technical data to support hotels, offices and public commercial spaces. The goal is straightforward: help customers create memorable floors while giving specification teams the information they need to make responsible, project-specific decisions.
