ISO 10295-1:2007

Overview

ISO 10295-1:2007 - Fire tests for building elements and components: Fire testing of service installations - Part 1: Penetration seals specifies a standardized furnace test method to evaluate the performance of penetration sealing systems where services (pipes, cables, conduits, etc.) pass through fire separating elements (walls, floors). The standard defines heating conditions, test construction, instrumentation and pass/fail criteria to assess whether a penetration seal maintains integrity and insulation of the separating element during a fire.

Key topics and technical requirements

• Scope & limitations
  • Assesses effects of penetrations on element integrity and insulation, and on the sealing system and services.
  • Does not address load‑bearing capacity, quantitative smoke/gas leakage rates, or seal performance under service movement/stress.
• Test setup
  • Furnace minimum internal size: 1 m × 1 m × 1 m with at least 200 mm clearance between seal perimeter and furnace wall.
  • Test specimens use full‑size penetrations; minimum 200 mm distance from penetration perimeter to heated element edge.
• Orientation and pressure
  • Both wall and floor orientations covered; vertical assemblies require a pressure of (20 ± 2) Pa at the bottom penetration; horizontal elements require (20 ± 2) Pa at 100 ± 10 mm below underside.
• Specimen construction
  • Fire separating elements should be representative of in‑service construction (examples: wall thickness ≥ 70 mm, floor thickness ≥ 100 mm, typical material densities specified).
• Services and service support
  • Services selected to represent intended application; uninsulated exposed length minimum 300 mm, unexposed length maximum 500 mm.
  • Multiple penetrations require ≥ 200 mm separation to avoid interaction.
• Pipe end options
  • Permitted end conditions include capped/uncapped combinations; capping may be mineral wool/ceramic fibre disc (50 ± 10 mm thick, density 150 ± 50 kg/m³) or welded discs.
• Procedures and reporting
  • Pre‑test conditioning and instrumentation follow ISO 834‑1; full test report requirements and direct field of application rules are specified.

Applications and who uses it

• Fire testing laboratories performing ISO 10295-1:2007 fire resistance tests on penetration seals.
• Manufacturers of penetration sealing systems, fire collars, intumescent seals and passive fire protection products for product development and certification.
• Building designers, fire safety engineers and specifiers who need validated fire performance data for service penetrations.
• Regulatory bodies and certification organizations that reference standardized fire test results for approvals and classifications.
