Generic Spec - “Penetrations and joints in fire rated elements
should assure same fire rating as the element they go through.”
At the same time, if the project specifications are comprehensive and
well-studied, it not only provides a good clarity to the contractor, but
also helps the right budgeting and compliance with national building
codes and standards. The comprehensive specification text such
as the one mentioned below can be referred to as an example.
Comprehensive Specification - “For large openings and complex
penetrations made to accommodate cable trays and bundles,
multiple steel and copper pipes, Pre-formed block CFS BL made
from intumescent polyurethane material for temporary or permanent
firestop sealing around cables, cable bundles and conduits.
Surface burning characteristics according UL 723 (ASTM E84-
01): Flame spread index 10 and smoke development index 15. The
density is 0.27 g/cm³ and the expansion temperature (intumescent
activation) is around 392 °F (200°C). Seismic tested on mechanical
performance, smoke and fire-ratings. Application to be done by
HAFSC (_____ accredited firestop specialty contractor) and
applicator needs to submit Documanager generated report with all
application photos and relevant UL 1479 certificates or EJ solution
given by manufacturer.
For the information of readers, this book also contain the annexure
A, which highlights few firestop test reports from UL or Intertek
laboratories. This is provided to the reader for reference purposes
only as there are many such systems available among many
manufacturers and these are only some examples.
