What Is ASTM E814 Firestop Penetration Fire?
ASTM E814, titled Standard Test Method for Fire Tests of Penetration Firestop Systems, is the standard used to evaluate the fire-resistance performance of firestop systems: the materials, devices, and assemblies used to seal openings in fire-rated walls and floors where pipes, cables, cable trays, conduits, or ducts pass through. These penetrations are necessary for building mechanical, electrical, and plumbing systems, but if left unprotected, they create a path for fire, smoke, and heat to spread between fire-rated compartments. ASTM E814 provides a standardised, repeatable method for confirming that a specific firestop system, installed around a specific penetrating item configuration, will hold back fire for a defined period.
At a high level, the test involves building a specimen wall or floor assembly representative of field construction, installing the firestop system around the penetrating item(s) as they would be installed on site, and exposing one face of the assembly to a controlled fire inside a test furnace. The furnace follows a standard time-temperature curve, the same exposure curve referenced in ASTM E119, for a specified duration. Thermocouples on the unexposed side and on the penetrating items monitor temperature rise throughout, while observers watch for flame passage through the firestop. Immediately afterwards, a duplicate specimen undergoes a hose stream test, applying water under pressure to evaluate resistance to the physical impact and thermal shock of fire suppression.
From these observations, the standard establishes two ratings: the F Rating, based on how long the system prevents flame passage, and the T Rating, based on how long the system limits temperature rise on the unexposed side. Because firestop failures can compromise the fire compartmentation that life-safety and property-protection strategies depend on, ASTM E814 testing is central to code compliance, product listings, and engineering judgments throughout building construction.
Applications and Benefits of ASTM E814 Firestop Penetration Fire Testing
Scope
- Evaluates the performance of penetration firestop systems under a standard time-temperature fire test followed by a hose stream test.
- Establishes an F Rating, based on flame occurrence on the unexposed surface of the firestop system during the fire exposure period.
- Establishes a T Rating, based on the temperature rise (and any flame occurrence) recorded on the unexposed side of the firestop system and on the penetrating item.
- Requires a supporting construction, a fire-rated wall or floor assembly, fabricated to represent the building element the firestop system is intended to protect.
- Applies to firestop systems installed around actual or representative penetrating items, including pipes, cables, cable trays, conduits, and ducts, whether single penetrations or multiple penetrations through a common opening.
- Covers a wide range of firestop materials and configurations, including mineral wool, ceramic wool, sealants, caulks, putties, wraps, intumescent materials, and cast-in-place devices.
- Excludes membrane penetrations evaluated as part of floor-ceiling assemblies tested to ASTM E119 and does not apply to penetrations through load-bearing wall assemblies covered separately by that standard.
- Uses the same furnace exposure basis (standard time-temperature curve) referenced in ASTM E119 fire tests of building construction and materials.
- Is closely related to UL 1479, which uses a comparable methodology and adds optional L (air leakage) and W (water leakage) ratings.
- Supports the development and evaluation of firestop products and systems for building code compliance, third-party product listings, and engineering judgment documentation.
Applications
- Qualification testing of penetration firestop products and systems by manufacturers seeking code-compliant listings.
- Verification testing for electrical, mechanical, and plumbing contractors installing firestop systems in fire-rated wall and floor assemblies.
- Support for building code compliance and inspection requirements on new construction and renovation projects.
- Development of engineering judgments for field conditions that fall outside the exact scope of an existing tested system.
- Product comparison and selection by architects, engineers, and specifiers evaluating firestop systems for a project.
- Due diligence and documentation for fire-stopping subcontractors and general contractors on life-safety-critical projects.
- Supplemental data supporting related evaluations such as UL 1479 testing and third-party product certification programs.
Benefits
- Provides an independent, standardised basis for confirming that a firestop system performs as intended under real fire conditions.
- Distinguishes flame-blocking performance (F Rating) from heat-transfer performance (T Rating), giving specifiers the information needed for combustible-material and life-safety applications.
- Verifies that a firestop system can withstand the physical shock of a hose stream immediately following fire exposure, not just static fire exposure alone.
- Generates documented, third-party test data that supports code compliance submittals and building inspections.
- Helps manufacturers and contractors avoid costly field failures, callbacks, or compliance issues tied to unproven firestop configurations.
- Supports informed product selection among competing firestop materials and system designs.

ASTM E814 Firestop Penetration Fire FAQs
ASTM E814 and UL 1479 are equivalent firestop test standards evaluating penetration fire resistance. ASTM is a consensus standard, while UL 1479 is UL’s version. Both measure F and T ratings under similar fire exposure conditions.
In ASTM E814, the F rating indicates how long a firestop system prevents flame passage. The T rating measures time until the unexposed side temperature rises 325°F above ambient, indicating heat transfer resistance.
ASTM E814 testing duration depends on the required rating, typically 1 to 4 hours of fire exposure. Including setup, curing, instrumentation, and reporting, the full testing process may take several days to weeks.
Firestop products used for through-penetrations, such as sealants, collars, wraps, sleeves, and composite systems around pipes, cables, and ducts, require ASTM E814 testing to ensure compliance with fire-resistance-rated wall and floor assemblies.
The F rating measures resistance to flame passage through a firestop system, while the T rating measures resistance to heat transfer. F focuses on fire containment, whereas T evaluates insulation performance and temperature rise limitation.
ASTM E814 evaluates penetration firestop systems by exposing them to a standardized time-temperature fire test and hose-stream test. Performance is assessed using F and T ratings, based on flame passage and temperature rise on the unexposed side.
UL 1479 and ASTM E814 evaluate penetration firestop systems under standardized fire and hose-stream exposures. The tests assess the system's ability to prevent flame passage and limit temperature rise through protected penetrations.
