CS-2000 Floor Stain | Floor coloring meets A (A2-s1) fire rating requirements
In factory floors, underground garages, and public building projects, fire resistance ratings are a mandatory requirement for engineering approval. Most floor coloring products focus solely on color and application performance, often overlooking fire safety metrics. CS-2000 Floor Coloring Agent has passed third-party authoritative testing, achieving combustion performance compliant with ** GB 8624-2012 A (A2-s1) grade**, providing a coloring solution for flooring projects with fire safety requirements.
## Why Is Combustion Performance Important for Floor Coloring Materials?
When discussing floor fire resistance, many focus on the substrate and topcoat, often overlooking pigments. @Li Wenzhang
Pigments are a critical color-matching component in flooring systems. If their fire performance fails to meet standards, it directly compromises the fire rating of the entire flooring assembly, potentially causing the project's fire safety approval to be rejected. Underground spaces, large industrial facilities, and public areas in malls have strict mandatory fire resistance requirements for building materials; the performance of every layer must not be overlooked.
Standard colorants typically prioritize tinting strength and dispersion, often lacking third-party fire performance certification. To balance aesthetic customization with fire code compliance, the colorant itself must undergo standardized flammability testing.
CS-2000 Floor Coating | Certified A (A2-s1) Low-Smoke Fire Resistance
CS-2000 floor coating samples submitted to CTI Farjian for combustion performance testing in accordance with the national standard system for flooring materials.
✅ Compliance Criteria:
- GB/T 14402-2007 "Determination of heat of combustion for building materials and products"
- GB/T 11785-2005 "Determination of Burning Behavior of Floor Coverings — Radiant Heat Source Method"
✅ Classification: GB 8624‑2012 "Classification of Combustion Performance for Building Materials and Products"
** Test sample inspection conclusion: Combustion performance meets Class A (A2‑s1). **
### Core Metrics Explained
1. Critical Heat Flux CHF ≥ 11kW/m²
Class A2 floor materials require ≥8.0kW/m². The measured values exceed the standard limits, demonstrating strong resistance to flame radiation.
2. Smoke generation level: S1, Smoke output 79%×min
S1 is the optimal smoke emission grade, releasing minimal smoke during a fire to reduce secondary harm.
3. Heat of combustion meets the Class A2 limit.
The pigment layer and the total heat of combustion for the entire test specimen both meet the A2 flooring material criteria.

## Final Thoughts
Flooring projects: aesthetics and compliance are both essential.
Color aesthetics address the surface needs of flooring, while fire safety is an uncompromising baseline for any project. CS-2000 Floor Colorant not only enables precise color customization but also passes authoritative third-party fire testing, providing robust support for fire safety documentation and regulatory approval.
