to Remove Hose Stream Requirements Fail During Yesterday's Hearings
Numerous proposed changes to the International Fire Code (IFC)
relating to whether glazing products used in fire-rated applications
should be required to pass the hose stream test were heard and ultimately
disapproved by the code committee during Tuesday's hearings. Presented
on behalf of SAFTI FIRST, those disapproved included FS122, 123,
124, 126, 127, 128, 129.
FS122 proposed that in lieu of meeting hose stream requirements,
glazing material used in door assembly parts, such as transoms and
sidelites, be tested in accordance with a heat flux that would not
exceed 12 Kw/m2 for 20 minutes.
Thomas Zaremba on behalf of Pilkington spoke in opposition. He
said there were no substantial reasons to add a heat flux requirement,
and that UL does not test to a heat flux because no jurisdiction
Also disapproved, FS123 proposed that 20-minute door assembly glazing
material, other than that used in the door itself (i.e. transom
lites and sidelites), be tested in accordance with NFPA 252 or UL10,
and be exempt from the hose stream test. The code change committee
voted to disapprove the proposal, saying there was no technical
justification to do so.
Relating to the marking of safety glazing in hazardous locations,
FS124 proposed that certain sections of the code be changed to include
"fire-protection and fire-resistance-rated glazing complying with
the safety glazing requirements of Chapter 24 shall bear a label
or other identification issued by an approved agency showing the
information required in Section 2406.2, and shall bear the marking
Bill Koffel on behalf of the Glazing Industry Code Committee spoke
in opposition stating that the code already says glazing has to
comply with chapter 24 and that labeling is also already required.
Zaremba agreed and said the federal standard (CPSC 16 CFR) mandates
that manufacturers test and label their glass. He said there was
no justification as to why the code should change. The committee
agreed saying there was nothing wrong with the current code.
FS 126, 127, 128 and 129, which sought to exempt various glazing
materials from the hose stream test were also disapproved, as the
code committee saw no reason to remove the requirement.
In addition, SAFTI FIRST proposed FS 130, 131, 133 and 134 to "clarify
the code." The four proposals were disapproved by the committee.
Both FS130 and FS131, for example, proposed changes to "clarify
the reference to traditional wired glass as fire protection-rated
glazing," explaining "traditional wired glass should be designated
as fire protection-rated glazing to be consistent with how other
types of glazing products are described."
In regards to table 715.5, FS133 and 134 proposed changes to clarify
the code saying, "a fire window assembly with fire protection-rated
glazing is rated ¾ hour. Glazing material rated 1 hour or more needs
to be fire resistance-rated glazing to provide the required temperature
The day, however, wasn't a complete loss for SAFTI FIRST, as some
of its proposals, FS120, 135 and 136, were approved.
According to code documents, FS120 will make the code text consistent
with NFPA 80 (2006) provisions 126.96.36.199 and 188.8.131.52, which specify
the limitations on doorframes with transom and sidelites. This code
revision brings the NFPA 80 clarification of the limitations on
sidelite and transom doorframes into the IBC, where code enforcers
and other code users can identify the limits, rather than having
to refer to NFPA 80.
Also approved, FS135 is a clarification and addition to the code
that address the rating requirements for interior windows. The proposal
to 7184.108.40.206 addresses 20-minute windows tested to NFPA 257 that
are specified in table 715.5 for ½-hour fire partitions. According
to the proposal, "since a ½-hour fire resistance-rated fire partition
assembly is tested to ASTM E119 without the hose stream test, and
fire doors tested for 20-minutes as required in Table 715.4 are
not subject to the hose stream test, for consistency in the code,
the fire window component of a ½-hour fire partition should be likewise
exempt from the hose stream test under NFPA 257."
FS136 also relates to interior fire window assemblies. To clarify
the rating requirements of interior windows, the code change proposal
states "where ¾-hour fire protection window assemblies are permitted,
fire-protection-rated glazing requiring 45-minute opening protection
in accordance with Table 715.5 shall be limited to fire partitions
designed in accordance with Section 708 and fire barriers utilized
in the applications set forth in Sections 706.3.6 and 706.3.8 where
the fire resistance rating does not exceed one hour."
Code change hearings continue through Friday this week.
