Official SGS Test Report: Flexible Stone Achieves 99.93% Antiviral Activity Rate

Meta Description :
Read the SGS antiviral test report for our Flexible Stone. Tested against Influenza A (H1N1) under ISO 21702:2019, our material achieved a 99.93% antiviral activity rate, ensuring a healthier and safer environment for public spaces.


1. Report Overview

This article presents the official SGS test report (Report No. GZIN2509003897PL12-1_EN) evaluating the antiviral properties of our Flexible Stone. Conducted by SGS-CSTC Standards Technical Services Co., Ltd., the test measures the material’s ability to inactivate the Influenza A virus (H1N1). The exceptional result confirms that our material provides active hygienic protection, making it a revolutionary choice for Flexible Stone Engineering in healthcare, educational, and high-traffic public Facade Retrofit or interior renovation projects.

2. Data Analysis: The Science of Active Protection

According to the test results, after 24 hours of contact with the virus, the treated Flexible Stone samples demonstrated an antiviral activity rate of 99.93%.

Engineering Value for Healthy Buildings:

  • Proactive Hygiene: Unlike standard wall materials that merely act as a surface where viruses can linger, our Flexible Stone actively inactivates up to 99.93% of the Influenza A virus within 24 hours. This significantly reduces the risk of cross-infection via surface contact.
  • Ideal for Sensitive Environments: Combined with our Class A non-radioactive certification, this antiviral feature makes the material perfect for hospitals, clinics, schools, kindergartens, and food processing facilities.
  • Supports Green Building Certifications: This data provides a massive boost for projects aiming for WELL Building Standard or LEED certification, demonstrating a strong commitment to occupant health and safety.

3. Test Methodology

The SGS evaluation was conducted strictly under the international standard ISO 21702:2019 (Measurement of antiviral activity on plastics and other non-porous surfaces).

  • Test Standard: ISO 21702:2019
  • Test Virus: Influenza A virus H1N1 (ATCC-VR-1469)
  • Contact Time: 24 hours
  • Test Result: Antiviral activity rate ≥ 99.93%
  • Calculation Formula: [(B-C)/B] × 100, where B is the infectivity titre of untreated specimens and C is the titre of treated specimens after 24h.

Note: The test report explicitly states that it is intended for internal quality control and R&D. For official bidding or compliance verification, the specific SGS report number (GZIN2509003897PL12-1_EN) should be referenced.

4. FAQ

Q1: What does a 99.93% antiviral activity rate mean?
A: It means that within 24 hours of the Influenza A virus (H1N1) coming into contact with the Flexible Stone surface, 99.93% of the virus is inactivated. This prevents the wall from becoming a medium for virus transmission.

Q2: Can this material be used in hospitals or schools?
A: Yes, absolutely. Because of its high antiviral activity, zero radiation (Class A), and non-toxic composition, Flexible Stone is highly recommended for hospitals, schools, and other public areas where hygiene and safety are paramount.

Q3: How does this test simulate real-world conditions?
A: The ISO 21702:2019 test simulates a scenario where virus-containing droplets land on the wall surface. The 24-hour contact time measures how effectively the material’s surface eliminates the virus under standard environmental conditions.

Q4: Does the antiviral property affect the appearance or durability of the material?
A: No. The antiviral properties are integrated into the material’s structure and surface. It does not compromise the aesthetic finish, flexibility, or the 1500-hour weather resistance of the Flexible Stone.
