Xinrun Stone Soft Porcelain Products Earn International Authoritative Certifications, Multiple Performance Indicators Reach Industry-Leading Levels

July 18, 2026 — The soft porcelain products independently developed by Guangdong Xinrun Stone New Materials Co., Ltd. (hereinafter "Xinrun Stone") have recently passed a series of rigorous tests conducted by SGS, an internationally authoritative testing organization, earning authoritative recognition including GB 8624 A(A2-s1, d0) fire classification certification, CE certification, and multiple physical and environmental performance certifications. This signifies that the product has reached the forefront of the industry in core indicators such as safety, environmental protection, and durability, setting a new benchmark for the development of China's green building materials industry.

Core Strength: A2 Fire Classification and CE Certification, Building a Solid Safety Defense

The fire performance of building materials is the primary guarantee of life and property safety. Xinrun Stone's soft porcelain products performed excellently in testing according to GB 8624-2012 "Classification for Burning Behavior of Building Materials and Products," achieving a combustion performance rating of GB 8624 A(A2-s1, d0). The test report shows that its gross calorific potential (PCS) is 32.5 MJ/kg, the fire growth rate index (FIGRA₀.₂MJ) is 356.8 W/s, the smoke production characteristic rating reaches s1 level, and the flaming droplets/particles rating is d0 level, meaning no flaming droplets during testing. These data fully demonstrate that the material is non-combustible when exposed to fire, produces low smoke, and can effectively control fire spread, making it suitable for high-rise buildings and public spaces with stringent fire safety requirements.

Furthermore, the product has also passed CE certification under the EU EN 15102:2007+A1:2011 standard. The certificate of conformity, numbered IN-GZ-CP-5627-25094, confirms that Xinrun Stone's soft porcelain meets the requirements of the EU Construction Products Regulation (Regulation 305/2011/EU), providing a strong quality endorsement for its entry into the European and global markets.

All-Round Performance: Multi-Dimensional Certification from Physical Properties to Green Environmental Protection

In addition to the core fire safety certification, a series of reports issued by SGS also verify the outstanding performance of Xinrun Stone's soft porcelain across multiple dimensions:

• Durability and Stability: After 1,500 hours of artificial weathering test, the sample showed no cracking, blistering, or peeling, with a chalking rating of only Grade 2, demonstrating excellent weather resistance that ensures long-term aesthetics of building exteriors. Meanwhile, its dimensional change upon heating in the X and Y directions was only 0.06% and 0.03% respectively, far better than the national standard requirement of ≤0.25%, guaranteeing dimensional stability under various climatic conditions.
• Physical and Aesthetic Properties: The product performs excellently in balancing aesthetics and functionality. Its flexibility allows it to bend around a 200 mm-diameter cylinder without cracking, easily meeting the decorative requirements of various curved, cylindrical, and irregular-shaped building surfaces. Its surface density is only 3.96 kg/m², with a water absorption rate of 11.3%, and its lightweight characteristics effectively reduce building load.
• Health and Environmental Protection: The product also performs outstandingly in terms of environmental health. The internal exposure index (Iᵣₐ) and external exposure index (Iᵣ) of radionuclide testing are both less than 0.1, far superior to the national Class A decorative material standard, with no restrictions on scope of use. Additionally, its antiviral activity rate reaches up to 99.93% (against Influenza A virus H1N1), and its antibacterial rate exceeds 99.9% (against Escherichia coli and Staphylococcus aureus), providing a new material choice for creating healthy and safe indoor environments.
