Photoluminescent Product Standards: IBC, IFC, ASTM, UL & APTA Compliance
Photoluminescent egress products must meet a range of national and industry-specific standards to ensure safety, visibility, and durability in emergency situations. Below is a summary of the key requirements under the International Building Code (IBC), International Fire Code (IFC), ASTM, UL, and APTA standards.
IBC & IFC (International Building and Fire Codes)
The IBC (for new construction) and IFC (for existing buildings) require luminous egress path markings in high-rise buildings (typically over 75 feet) for occupancies such as Group A, B, E, I-1, M, and R-1
Key requirements include:
- Photoluminescent or self-luminous materials must be used in stair enclosures, landings, handrails, and door frames.
- Materials must be non-electrical and remain visible during power outages.
- Must be charged by at least 1 footcandle (11 lux) of fluorescent lighting for 60 minutes.
- Minimum luminance: 30 mcd/m² at 10 minutes, 5 mcd/m² at 90 minutes
- Products must comply with UL 1994 or ASTM E2072.
ASTM Standards
ASTM provides the technical specifications and test methods for photoluminescent materials:
- ASTM E2072: Standard Specification for Photoluminescent Safety Markings
- ASTM E2073: Test Method for Photopic Luminance of Photoluminescent Markings
- ASTM E2030: Guide for Recommended Uses of Photoluminescent Safety Markings
These standards define:
- Luminance decay rates
- Durability and visibility
- Material performance under various lighting and environmental conditions
UL Standards
UL standards are essential for product listing and certification:
UL 924: Applies to emergency lighting and exit signs. Requires:
- 90-minute visibility after power loss
- Visibility from 100 feet in total darkness
UL 1994: Applies to luminous egress path marking systems, including:
- Floor markings
- Stair nosings
- Door hardware and frames
- Directional signage
UL 1994-listed products must undergo annual retesting and meet strict criteria for brightness, longevity, and safety.
APTA (American Public Transportation Association)
For passenger rail equipment, APTA’s PR-PS-S-006-23 standard (2023) defines:
- Low-Location Exit Path Marking (LLEPM) systems for railcars
- Requirements for interior and exterior emergency signage
- Photoluminescent and retroreflective materials for visibility in smoke or low-light conditions
- Placement, durability, and informational content of markings and signs
APTA (American Public Transportation Association)
For passenger rail equipment, APTA’s PR-PS-S-006-23 standard (2023) defines:
- Low-Location Exit Path Marking (LLEPM) systems for railcars
- Requirements for interior and exterior emergency signage
- Photoluminescent and retroreflective materials for visibility in smoke or low-light conditions
- Placement, durability, and informational content of markings and signs
This standard ensures that passengers and crew can safely locate and operate emergency exits during evacuations.
