Product No: SMT-SM207
UL 1278 Figure 10.2 Bar Probe is a specialized safety tool for testing movable, wall-hung, and ceiling-hung electric room heaters. It features a hardened steel “bar” for durable, consistent access simulation—critical for checking if hazardous parts (like hot elements or mechanical components) are out of reach. Paired with a lightweight nylon handle for safe, easy grip during testing, it aligns strictly with UL’s safety standards. Compact and easy to maneuver, it’s essential for verifying heater compliance, ensuring end-users are protected from burns or mechanical injuries.
Specifications:
• Probe Type: Bar Probe (compliant with UL 1278 Figure 10.2 for electric room heater testing)
• Probe Material: Hardened steel (resists wear, maintains shape for repeated testing)
• Handle Material: Nylon (insulating, non-slip, and heat-resistant for safe operation)
• Key Dimensions:
– Probe Section 1: 1/16 inch (1.6 mm) diameter
– Probe Section 2: 1/2 inch (12.7 mm) diameter
(precision-machined to match UL 1278 Figure 10.2 requirements)
• Core Function: Verifies inaccessibility of hazardous parts (hot elements, moving components) in electric room heaters
• Applied Force: No appreciable force (mimics accidental, light contact by users)
Test Procedures:
• Inspect the probe for damage (e.g., bent steel bar, cracked nylon handle).
• Power on the electric room heater and let it reach normal operating temperature.
• Hold the nylon handle and align the hardened steel bar with potential access points (e.g., heater grilles, gaps).
• Gently guide the bar toward hazardous parts (e.g., glowing elements, fans).
• Check if the bar touches any dangerous components.
• Record whether the heater meets safety requirements (pass/fail).
Applications:
• Safety testing of movable electric space heaters (per UL 1278 Figure 10.2).
• Compliance checks for wall-hung electric room heaters to block access to hot elements.
• Verification of ceiling-hung electric heaters (e.g., office or workshop models) for mechanical hazard protection.
• Quality control for small commercial electric heaters (e.g., restaurant patio heaters) during manufacturing.
• Post-production safety audits of residential electric room heaters to ensure UL 1278 compliance.
