For fire safety review of flooring projects, the fire rating is a critical requirement. Most people focus on the base coating and topcoat, but one component often overlooked is the pigment.

Pigments are the color-matching component in flooring systems. At first glance, they seem to be just about adding color and have nothing to do with fire safety. However, if a pigment fails fire performance tests, it can significantly downgrade the fire rating of the entire flooring system. Even if you select A-class base materials and A-class topcoats, an untested or non-compliant pigment can cause the whole system to drop to B1 or lower.

Underground parking, large factories, and public retail areas require mandatory fire-resistance ratings for construction materials. Failure to pass fire safety review can halt project acceptance, delay schedules, and compromise performance at every level.

Standard colored products often focus on color strength and spreadability, while fire performance is frequently not fully tested by third parties. It's not that they can't pass; it's just that they haven't been tested. Without testing data, they cannot be submitted for approval.

CS-2000 Floor Coating: Class A Fire-Resistant with Certified Test Report

CS-2000 flooring stain was submitted to CTI Huace Yuanjian for testing. Complete combustion performance tests were conducted in accordance with the national standard system for floor materials.

Testing criteria based on three standards:

• 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 Using a Radiant Heat Source"

• GB 8624-2012 "Classification of Combustion Performance of Building Materials and Products"

Conclusion: Combustion performance meetsClass A (A2-s1)。

Three core metrics, translated one by one.

Critical Heat Flux CHF ≥ 11kW/m²

This metric measures a material's resistance to flame radiation. Higher values indicate greater resistance to ignition.

Class A2 floor material requires CHF ≥ 8.0kW/m². CS-2000 measured value is ≥ 11kW/m², which is 37% above the standard limit. This isn't just passing the threshold; it includes a safety margin.

Smoke production level S1, smoke output 79% × min

In a fire, the real danger isn't the flames—it's the smoke. Dense smoke reduces visibility, causes suffocation, and leads to stampedes; these secondary hazards are often more deadly than the fire itself.

Smoking level is rated in three tiers: S1 (best), S2 (medium), and S3 (worst). CS-2000 achieves the top S1 rating. Smoke emission at 79% × min indicates low smoke release during combustion, providing more evacuation time in the event of a fire.

Heat of combustion meets the A2 classification limit.

Calorific value measures the heat released when a material burns. Higher heat leads to faster fire spread. The coloring layer of CS-2000 and the total calorific value of the complete test sample both meet the A2 classification criteria for floor coverings.

It's not about passing at a single layer; the entire test specimen must be tested and pass together.

Test results apply only to the submitted sample.

Which projects require coatings to pass fire safety testing?

In short, for any flooring project requiring fire code approval, the colorant cannot be blank.

• Industrial factory flooringFire safety acceptance for industrial facilities mandates specific grade requirements for flooring materials.

• Underground Garage Floor SystemUnderground spaces pose evacuation challenges and require stricter fire protection standards.

• Supermarkets, public venues, and other public infrastructure projectsPublic building fire safety approval is a mandatory requirement.

• Any construction project with specific requirements for the combustion performance of flooring materials

During the review process, the fire department requires test reports for every material used across all levels of the complete system. Since there is no report for the colorant, a critical component is missing. Without it, approval cannot be granted.

Style and compliance aren't mutually exclusive.

Flooring systems: Aesthetics is the surface-level need; fire safety is the non-negotiable baseline.

Many projects stall at the fire safety review stage not due to poor materials, but because a specific layer was never tested or lacks a report. Colorants are often the overlooked layer.

CS-2000 Floor Stain: Achieve precise floor color matching while passing authoritative third-party fire safety tests. With an A-level fire rating report, you can complete fire code submissions without needing additional documentation.
