AD 272: Guidance on fire protection available

The report entitled Interim Guidance on the use of intumescent coatings for the fire protection of beams with web openings is now available on Steelbiz.

This publication provides background information to AD 269, which appeared in the November/December issue of NSC (Vol. 11, No. 6). The document also contains more comprehensive guidance on determining an appropriate thickness of fire protection for beams with web openings. The document gives the background to the structural and thermal models used to generate the design tables and information on the test evidence that supports this advice. A design example demonstrating the application of the design tables is also included. To locate the report, go to Steelbiz ( and click on ‘What’s New’
