TR7 Test and evaluation method of systems to provide 60 minutes fire resistance for nailed gusset connections (1990)

Product Description

Technical Recommendation 7 outlines a comparative test and evaluation method using small-scale unloaded specimens, to demonstrate that a particular protective system can be used over nailed gusset connections to achieve a 60-minutes FRR.

This technical recommendation is suitable for assessing protection of nailed gusset connections in portal frames where the live load is less that 0.4 kPa, typical of those supporting a roof system.
