EN TESTED FIRE RATED DUCTING SYSTEMS

Our understanding to the current status with regards to the supply of EN tested fire resisting ducting systems is summarised below.

The Construction Products Regulation (CPR) was implemented with effect from the 1 July 2013. This regulation requires the adoption of European Standards where a Harmonised Product standard exist. In the case of fire resistant ducting the product standards are BS EN 15871(we understand to be ratified in the next 12 months) and BS EN 12101-7 and the test standards are BS EN 1366 parts 1, 8 and 9.

Fire Protection Ltd have invested a substantial amount of time, effort and money in developing and testing a range of products to meet the new standards. To date we have carried out in excess of 30 duct fire tests in accordance with the BS EN 1366 standard. We are pleased to confirm that we can supply fire resistant duct tested in accordance with BS EN 1366 parts 1, 8 and 9. Our tests cover horizontal and vertical orientations, rectangular and circular profiles and for fire inside and fire outside exposures. The applications covered include ventilation, smoke control and kitchen extract ducts. These tests are additional to the comprehensive range of testing to BS476 Part 24 that we had previously carried out.

In the UK BS476 Part 24 has been superseded and replaced by BS EN test standards. There are transitional arrangements covering certain projects where work had started, or work is subject to an initial notice or building notice, or full plans application prior to 1 July 2013, works after this date require compliance with the CPR.

The selection and use of appropriate materials that are fit for purpose in terms of materials and workmanship is a requirement under Approved Document B. Regulation 7 is the element of building regulations relative to materials and workmanship and Approved Document 7 supports this regulation. The 2013 edition of Approved Document 7 recognizes the introduction of the CPR requiring the use of EN tested products.

Both the Association of Specialist Fire Protection (ASFP) and BESA (formerly HVCA) have issued documentation (DW144) confirming the requirement to the use of EN tested fire resistant duct systems.

As time goes on an ever increasing number of buildings will have to incorporate fire resistant ducts tested in accordance with BS EN 1366.
