NEW QUESTION # 40
Sealants used to resist passage of air in construction Type IV-A, shall be in accordance with which of the following standards?
Answer: A
NEW QUESTION # 41
Both surfaces of a two-hour-rated mass timber wall that serves as a required separation between a Group R and Group I-2 occupancy in a Type IV-C building must be protected by at least which of the following?
Answer: A
Explanation:
The minimum additional protection is 1/2-inch gypsum board or an approved equivalent thermal barrier
, making option C correct.
The wall in the question functions as an occupancy separation. Under IBC Section 508.4.4.1, mass timber elements serving as fire barriers or horizontal assemblies separating occupancies in Type IV-B or IV-C construction must be separated from the building interior by an approved thermal barrier consisting of gypsum board at least 1/2 inch thick , or a material satisfying both applicable NFPA 275 thermal-barrier tests.
Because the wall separates two interior occupancies, each face is exposed to interior space; consequently, the thermal-barrier requirement applies to both surfaces .
This requirement must not be confused with the wall ' s two-hour fire-resistance rating. The underlying mass timber wall must independently satisfy the required two-hour assembly performance. The 1/2-inch gypsum protection is an additional thermal-barrier condition imposed because the rated separation is constructed of mass timber in Type IV-C.
Option D would provide substantially more gypsum protection than the specific occupancy-separation provision requires.

NEW QUESTION # 42
For Type IV-A, IV-B, and IV-C construction, each of the following materials on the exterior side of mass timber exterior walls is required to be noncombustible except:
Answer: C
Explanation:
The code provides a specific combustible-material exception for qualifying water-resistive barriers , making option D correct. The exterior-protection provisions for Types IV-A, IV-B, and IV-C require the exterior side of mass timber walls to receive noncombustible protection with at least a 40-minute assigned protection time, and components of the exterior wall covering are generally required to be noncombustible.
A water-resistive barrier may be combustible only where it satisfies stringent fire-performance criteria.
Among those criteria, the 2021 IBC limits peak heat-release rate and total heat release under ASTM E1354 and establishes flame-spread and smoke-developed limits under ASTM E84 or UL 723. The provision therefore does not create a blanket exemption for arbitrary combustible membranes.
Insulation, exterior cladding, and architectural components forming part of the regulated exterior wall covering must comply with the applicable noncombustibility requirements unless some other express code allowance applies. The WRB is the specifically identified exception tested by this question.
During inspection, product identification and fire-test documentation should be checked rather than assuming that a membrane qualifies merely because it is marketed as a water-resistive barrier.

NEW QUESTION # 43
In mass timber construction of Type IV-C, the fire-resistance ratings of bearing walls are permitted to be reduced by _____ where supporting a roof only.
Answer: A
Explanation:
The permitted reduction is one hour. Table 601 assigns a two-hour base fire-resistance rating to exterior and interior bearing walls in Type IV-C construction. Footnote "a" to the table permits the ratings of the primary structural frame and bearing walls to be reduced by one hour where those elements support a roof only.
Accordingly, a Type IV-C bearing wall that supports only roof construction may be assigned a one-hour rating after application of the permitted reduction. The allowance recognizes that the element is not carrying occupied floor levels above and therefore presents a lower consequence of progressive structural failure than a wall supporting one or more floors.
The reduction is not automatic merely because a bearing wall is located at the upper story. The approved structural documents must establish that the wall supports only the roof and does not carry floor loads, transfer loads, elevated mechanical platforms, occupied rooftop structures, or other construction that invalidates the condition.
Options A and B are not reductions specified by Table 601. Option D would eliminate the entire two-hour rating and is not permitted. The inspector should verify the applicable rating and the precise load path before accepting reduced fire protection at the top story.
References/Topics: 2021 IBC Table 601, Footnote "a"; Type IV-C bearing walls and roof-support rating reduction.
NEW QUESTION # 44
The time, in minutes, contributed to the fire resistance rating by the noncombustible protection of mass timber building elements, components, or assemblies, shall be established through a comparison of assemblies tested using procedures set forth in ASTM Standard:
Answer: A
Explanation:
The applicable standard is ASTM E119 , making option B correct. IBC Section 703.6 establishes a performance method for determining the number of minutes contributed by noncombustible protection applied to mass timber.
The methodology requires two otherwise identical assemblies to be evaluated using the procedures of ASTM E119 or UL 263 . Test Assembly 1 is tested without the protective covering. Test Assembly 2 incorporates the representative noncombustible protection, including its actual configuration, attachment details, joint treatment, accessories, and other relevant installation conditions. The protection contribution is then calculated by subtracting the fire-resistance time of the unprotected assembly from that of the protected assembly.
ASTM E119 is specifically designed to evaluate fire endurance of building construction and structural assemblies under standardized fire exposure. ASTM D3498, by contrast, is an adhesive specification referenced by the IBC for sealing certain mass timber interfaces. The other standards listed are not the prescribed comparative fire-resistance test for this determination.
