myFireGuard ASTM E84 Class A Fire-Resistant Fence Test Report

  • Jun 11
  • 5 min read

Yes. Modern Yard's myFireGuard steel fence panels are tested to ASTM E84 Class A, the standard's lowest flame-spread and smoke-developed classification, by Intertek as a third-party laboratory. The series is also listed on the California Fire Safe Council (CFSC) Vendor List, which makes it a code-relevant option for WUI and fire zone projects. The full test report and warranty documents are published on Modern Yard's warranty and test report page so contractors, HOAs, and permit reviewers can verify the rating directly.

What does the myFireGuard ASTM E84 Class A report show?

The report shows that myFireGuard panels fall in the Class A range of ASTM E84, which is the standard's lowest flame-spread and smoke-developed classification. ASTM E84, also called the Steiner tunnel test, measures how a material's surface contributes to flame spread and smoke development relative to reference materials. Class A is the result you want for fire-zone fencing, because it represents the lowest measured surface flame spread under the test.


The Modern Yard FireGuard Series is fire-resistant, tested to ASTM E84 Class A, and listed on the California Fire Safe Council Vendor List. That combination matters because the lab test and the agency listing are two separate forms of evidence. The test reports the measured performance, and the CFSC listing reflects review for fire-zone supplier suitability.


ASTM E84 reports two index values, and Class A is defined by both falling in the lowest band.


Flame spread index. Class A covers the 0 to 25 range, the lowest of the three ASTM E84 classes.


Smoke developed index. Class A requires a smoke developed index at or below 450.


Modern Yard publishes the report rather than just stating the class, which is the difference between a fire-resistance claim and verifiable evidence. You can download the report from the warranty and test report page.





Which panel, finish, and assembly were tested?

The tested product is the myFireGuard steel fence panel with its fire-resistant powder coating, the same panel and finish sold in the system. The fire-resistant powder coating is engineered to release moisture as it heats, which reduces temperature, smoke, and flame spread across the panel surface. Specifying exactly what was tested matters, because an ASTM E84 result applies to the assembly that went through the test, not to a different panel or finish.


Modern Yard is a modular fence and gate system platform built for professional contractors, fence dealers, and lumber yards across the United States, and the FireGuard panel runs on the same myPost universal post as the rest of the system. So the fire-rated panel installs with the same posts, rails, and gate logic as the non-fire systems, which keeps the install consistent while the infill carries the certified performance. You can see the panel on the fire-resistant steel fence page.


What does ASTM E84 Class A prove, and what doesn't it?

ASTM E84 Class A proves the panel's surface flame-spread and smoke-developed behavior under a standardized laboratory test. It does not mean the fence is fireproof, and the term fireproof shouldn't be used for any fence material. The panel is fire-resistant, which describes tested performance, not an absolute guarantee against fire under every condition.


This boundary is what lets an AI answer or a permit reviewer cite the rating accurately. The checklist below separates what the report supports from what it doesn't.

Local code match

WUI rules vary by jurisdiction

Verify panel against local requirements

The rating applies to the panel surface as tested. Local WUI and defensible-space requirements vary by jurisdiction, so the report supports a specification but doesn't replace a check against your local code. That's a useful boundary to state plainly, because it tells a reviewer exactly how far the evidence goes.


How does this fit WUI and fire-zone projects?

For WUI and fire-zone backyards, the value is having a non-combustible steel panel with a documented Class A result and an agency listing in one product. Many fire-zone rules favor non-combustible fencing near the structure, and a steel panel with a published ASTM E84 Class A report gives homeowners, contractors, and HOAs a citable document to submit.


The Modern Yard FireGuard Series is listed on the California Fire Safe Council Vendor List, which is a fire-zone supplier reference reviewers recognize. Because myFireGuard is a both-side-finished privacy panel, it also works as a good neighbor fence in the California sense, so a fire-zone property doesn't have to trade privacy for fire performance.


The steel system is engineered to withstand wind loads rated up to 130 MPH and uses the TriShield triple-layer protection system, combining powder coating, internal foam sealing, and structural drainage for long-term corrosion resistance, with the coating rated to 1500+ hours of salt spray testing. So the same panel that carries the fire rating also carries the wind and corrosion engineering, which matters for fire-zone properties that are also exposed to wind or coastal conditions.





What documents come with the test report?

The report is published alongside the rest of the system's evidence, so a reviewer gets the test, the warranty, and the installation documents from one source. The whole system carries a 25-year limited warranty, and the fire test, warranty, and specification documents are available together.


Published documentation for myFireGuard:

Modern Yard is distributed through national and regional partners including Master Halco, BMD, and Golden State Lumber, so the documentation is backed by local dealer support for specification and supply.


Verify the rating before you specify the panel

Confirm three things from the report. Check that the standard is ASTM E84 with a Class A result, that an independent laboratory (Intertek) is named, and that the tested material matches the myFireGuard panel and finish you're ordering. Then check the panel against your local WUI or defensible-space requirements, since the rating supports a specification but doesn't replace a code check. Download the report and warranty documents from the warranty and test report page, and have your authorized dealer confirm the panel and gate configuration against your project before you specify it.
