IBC: 703.2, 703.4

Proponent : Jeffrey Shapiro, representing Tyco Fire Products (jeff.shapiro@)

2018 Int ernat ional Building Code

Revise as f ollows:

703.2 Fire-resist ance rat ings. The fire-resistance rating of building elements, components or assemblies shall be determined in accordance with the test procedures set forth in ASTM E119 or UL 263, without the use of automatic sprinklers or any other fire suppression system being incorporated as part of the test, or in accordance with Section 703.3. The fire-resistance rating of penetrations and fire-resistant joint systems shall be determined in accordance Sections 714 and 715, respectively.

703.3 Met hods f or det ermining f ire resist ance. The application of any of the methods listed in this section shall be based on the fire exposure and acceptance criteria specified in ASTM E119 or UL 263. The required fire resistance of a building element, component or assembly shall be permitted to be established by any of the following methods or procedures:

1.

Fire-resistance designs documented in approved sources.

2.

Prescriptive designs of fire-resistance-rated building elements, components or assemblies as

prescribed in Section 721.

3.

Calculations in accordance with Section 722.

4.

Engineering analysis based on a comparison of building element, component or assemblies designs

having fire-resistance ratings as determined by the test procedures set forth in ASTM E119 or UL

263.

5.

Alternative protection methods as allowed by Section 104.11.

6.

Fire-resistance designs certified by an approved agency.

Delet e wit hout subst it ut ion:

703.4 Aut omat ic sprinklers. Under the prescriptive fire-resistance requirements of this code, the fire-resistance rating of a building element, component or assembly shall be established without the use of automatic sprinklers or any other fire suppression system being incorporated as part of the assembly tested in accordance with the fire exposure, procedures and acceptance criteria specified in ASTM E119 or UL 263. However, this section shall not prohibit or limit the duties and powers of the building official allowed by Sections 104.10 and 104.11.

Re a s o n : This proposal captures discussion points from previous cycles and provides a simpler approach to dealing with limiting the E119 test protocol to not include fire suppression systems. Although E119 doesn't allow this, it is understood that some interest groups have wanted the point emphasized in the IBC. In this proposal, the technical restrictions in 703.4 have been relocated to Section 703.2, since this is where compliance with E119 is established in the IBC. It's a more suitable place for the fire-suppression system limitation to reside. Alternatives to E119, including the reference to alternative methods per Section 104.11, will once again be consolidated in 703.3 without having to rely on a separate section (703.4) that is redundant with respect to performance-based alternatives. If you compare the text of this proposal with the current text in 703.4, you will see that it is closely aligned so as to maintain the intent of current provisions while eliminating confusion and concern associated with Section 703.4. Note that existing subsections of Section 703.2 are to be retained without change and are shown for clarity to see how the provisions fit together.

Cost Impact The code change proposal will not increase or decrease the cost of construction .

The proposal is a clarification of how the code applies.

IBC: 703.5, 703.5.1, 703.5.2 Proponent : Tim Earl, GBH International, representing self (tearl@) 2018 Int ernat ional Building Code Revise as f ollows: 703.5 Noncombust ibilit y t est s. The tests indicated in Sections Section 703.5.1 and 703.5.2 shall serve as criteria for acceptance of building materials as set forth in Sections 602.2, 602.3 and 602.4 in Types I, II, III and IV construction. The term "noncombustible" does not apply to the flame spread characteristics of interior finish or trim materials. A material shall not be classified as a noncombustible building construction material if it is subject to an increase in combustibility or flame spread beyond the limitations herein established through the effects of age, moisture or other atmospheric conditions. 703.5.1 Element ary Non-combust ible mat erials. Materials required to be noncombustible shall be tested in accordance with ASTM E136.

Except ion: Materials having a structural base of noncombustible material as determined in accordance with this section with a surfacing of not more than 0.125 inch (3.18 mm) thick that has a flame spread index not greater than 50 when tested in accordance with ASTM E84 or UL 723 shall be acceptable as non-combustible.

Delet e wit hout subst it ut ion: 703.5.2 Composit e mat erials. Materials having a structural base of noncombustible material as determined in accordance with Section 703.5.1 with a surfacing not more than 0.125 inch (3.18 mm) thick that has a flame spread index not greater than 50 when tested in accordance with ASTM E84 or UL 723 shall be acceptable as noncombustible materials.

Re a s o n : This current language is technically incorrect. The intent of the section title of Section 703.5.1 is to describe materials which are not layered and have a uniform structure throughout. This is complicated by the fact that the title is not reflected in the text of the section, so there is a disconnect. With Section 703.5.2, the problem is similar. While the title 'composite materials' isn't specifically used in the text, the text does describe a 'composite' of materials. In our efforts to correct the titles and have the titles clearly reflected in the text, we realized that a big part of the problem was the organization of these 3 sections. We believe our proposed solution results in clearer code and simpler code. This proposal does not result in any technical change to the code requirements. Cost Impact The code change proposal will not increase or decrease the cost of construction . This proposal cleans up incorrect language and will have no impact on construction costs. It is essentially editorial.

St andard Test Met hod f or Behavior of Mat erials in a Tube Furnace wit h a Cone-shaped Airflow St abilizer at 750oC

Re a s o n : Several of the I-Codes have varying definitions of the term "non-combustible material", each based upon the way in which the concept of "non-combustible" is used within that Code. Throughout the ICC code system, the concept of "noncombustible material" is based on the idea that the material should not ignite or burn when subjected to fire or heat. Our intent is to require the same pass/fail criteria as currently exists in ASTM E136, using all fo the thermocouples required by ASTM E136, but using the ASTM E2652 apparatus. When ASTM E2652 is used, the pass/fail criteria and methodology are those required by ASTM E136.

The concept of "noncombustible materials" and "noncombustibility" in terms of types of construction is widely used throughout the International Codes. The IBC, IFC, IEBC and IFGC do not contain a separate definition of "noncombustible", even though they use the terminology "non-combustible materials".

In common usage, the term "noncombustible" is used to denote materials which do not ignite or are not capable of sustaining combustion. The common Dictionary definitions for "noncombustible" are typically as follows:

Noncombust ible, adj ? incapable of being burned

(Merriam -Webster's International Dictionary of the English Language, Unabridged, 2013)

In the traditional use of the terminology and concept of "non-combustible" in the Codes has been based on acceptable performance when tested in accordance with ASTM E136, Test Method for Behavior of Materials in a Vertical Tube Furnace at 750 Degrees C . Materials passing the test are permitted limited flaming and other indications of combustion. However, these have traditionally been acceptable. Understandably, ASTM E136 does not replicate the full spectrum of actual building fire exposure conditions. However, this test method does provide an assessment indicating those materials which do not act to aid combustion or add appreciable heat to an ambient fire.

ASTM has published another standard ASTM E2652-16, entitled Standard Test Method for Behavior of Materials in a Tube Furnace with a Cone-shaped Airflow Stabilizer, at 750?C . This test method is similar to ASTM E136, but based on the international standard for Noncombustibility. The key difference between the two standards is in the equipment. The apparatuses in this test method and in Test Method E 136 is that the furnace tube in this test method has a conical air-flow stabilizer section attached at its bottom. Both test methods use cylindrical furnace tubes. Like ASTM E136, the test Standard does not include mandatory pass/fail criterion. It allows those criteria to be determined by the Codes or other users. Appendix X3 also contains a comparison of results obtained from this apparatus versus ASTM E136. ASTM E136 has already been revised to include ASTM E2652 as an alternate methodology.

Cost Impact The code change proposal will not increase or decrease the cost of construction .
