Technical Assessment

A technical assessment is a fire-resistance evaluation of an onsite application without direct test evidence. It uses established empirical methods of estimation and experience of fire testing conducted on similar firestop systems. This extends the scope of application by determining the limits for the design based on the tested constructions and performances obtained. The assessment will evaluate the potential fire-resistance performance if the elements were tested per BS 476: Part 20: 1987.

The assessment must be prepared and checked by product assessors with the necessary competence, who subscribe to the principles outlined in the PFPF guidelines for undertaking assessments in lieu of fire tests. The PFPF guidelines aim to give end users confidence that assessments that exist in the UK are of a satisfactory standard to be used in lieu of fire tests for building control and other purposes.
