What Do the UL Test Results Show?

UL document number EX27611 contains the following key information about the testing of PAF-222 [FK-5-1-12]:

• Class A: Reports a flame extinguishing concentration of 3.34% for surface burning fuels.

• Class B: Reports a flame extinguishing concentration of 4.5% for heptane fuel.

• Agent quality: Reports a purity of 99.9% and results for other properties based on the criteria stated in the document.

These results show that the FK-5-1-12 sample that was evaluated met the Class A and Class B fire extinguishing test requirements. However, the flame extinguishing concentration from testing is not the design concentration for an installed system. The design concentration must be calculated based on the standards and the conditions of use. Learn more at What is NFPA 2001?

Why Do Test Results Matter When Choosing a Fire Extinguishing Agent?

Checking test results helps users and system designers understand which fuel types an agent was evaluated against, and what scope of use is supported by data.

Frequently Asked Questions (FAQ)

1. What is UL 2166?

UL 2166 is a safety standard for Halocarbon Clean Agent Extinguishing System Units.

2. Does the UL document state that FK-5-1-12 can extinguish Class A and Class B fires?

The document reports Class A and Class B fire extinguishing tests, with flame extinguishing concentrations of 3.34% and 4.5% respectively, under the stated test conditions.

3. Can the 3.34% and 4.5% concentrations be used directly as system installation values?

Not directly. They are flame extinguishing concentrations from testing, not design concentrations for every area. Actual design must consider the relevant standards and factors.

4. Can FK-5-1-12 be used in server rooms and data centers?

A clean agent system can be considered for these areas, but you must check the product certification, the system design, and how well it fits the actual risks of the area before installation.
