Research and Development

A division of Imperial Ductwork Services Limited (IDSL), Imperial Fire Solutions (IFS) has developed a high-performance fire resistant service enclosure system (IFS-ES) and fire resistant ductwork system (IFS-DS).  Both systems have been rigorously tested in accordance with their relevant fire test standards.

IFS-ES

Our journey started in 2019 with thoughts on designing a BS EN 1366-5:2021 service enclosure, which must also be capable of meeting the T3 Thermocouple requirements detailed in the BS EN 1366-5:2003 edition. It is a requirement of the BS 8519:2020 code of practice that cable enclosures incorporate these T3 Thermocouples.

After reviewing several different materials and completing multiple ad-hoc tests to determine the performance of each material, we decided on a multi-layered system.

Full-scale testing exceeded our expectations, with results at 120 minutes indicating around 50°C below the T3 Thermocouple fail criteria.

After testing vertical, horizontal, fire inside and fire outside, we now have a system that surpasses everything our clients need.

Our system also has:

VOC emission testing

IPX6 powerful water jet without ingression

IP5X protection against the ingression of dust

Warringtonfire’s FIRAS installer accreditation

Ad-hoc full-scale test for 3-sided horizontal & vertical installation

Testing

When it comes to the products and systems we produce, the only way to ensure we meet industry standards of safety, quality, compliance and performance is through rigorous testing. That is why we use independent assessors like Efectis and PAVUS, who share over 100 years’ experience assessing the fire performance of products, systems and constructions.

Since April 2023, IFS has carried out 31 tests in conjunction with Efectis and PAVUS in testing houses located in Czech Republic, France and Turkey.

Overview of Tests

  • Single compartment smoke control ducts & multi-compartment duct systems
  • Single ducts tested to BS EN 1366-9:2008 passed the test at pressure level 3, achieving classification for 2 hours (E600 120)
  • Multi-compartment ducts provide the same level of performance but are tested to BS EN 1366-8, achieving EI 120 classification

Systems have been tested within a range of components to complete the system, and offer a complete direct field size range up to 1250mm x 1000mm or Ø1000m.
