prEN 1366-14 – Fire Resistance Tests for Service Installations: Partial Penetration Seals

Fire resistance tests for service installations – Part 14: Partial penetration seals

This standard is a critical resource in fire safety engineering, addressing how partial penetration seals—those used for single-sided penetrations like sockets, downlighters, media devices, or cables—maintain the fire resistance of walls, floors, and ceilings. The methodologies outlined enable manufacturers, fit-out contractors, and fire engineers to evaluate whether such seals restore or retain the fire-rated integrity of the construction where an opening exists on only one side.

It specifies the test specimen configuration (accounting for loads where seals are installed in floors/ceilings), the primary performance criteria (integrity and insulation), and the boundaries of field application. The interplay between the seal, the penetrating device, and the supporting element is rigorously assessed under fire exposure, with special notes on what is not addressed (e.g., stress from mechanical movement, smoke or toxic gas leakage, or downward fire spread).

Particularly relevant to fit-outs in commercial and residential buildings, prEN 1366-14 integrates seamlessly with European codes and guides, referencing EN 1363-1 for general fire testing and EN ISO 13943 for fire safety vocabulary. It supports enhanced safety by ensuring that even small or occasional penetrations do not compromise a fire-rated assembly.

Key highlights:

• Applies to seals for single-face penetrations (e.g., electrical outlets, downlighters)
• Evaluates both seal and surrounding construction for fire integrity and insulation
• Clarifies limitations, focusing test outputs on primary fire resistance rather than smoke/gas performance
