15-12-130 Approved protective assemblies.

   (a)   Fire-resistive door and shutter assemblies for specific conditions of use in the “Fire Protection Equipment List”, Underwriters' Laboratories, Inc., January, 1959, shall be acceptable as meeting the requirements of this section.

   (b)   Nothing in this section shall preclude the use of other opening protective assemblies meeting the required test standards.

(Prior code §  65-5.6)

15-12-140 Identification.

   Approved protective assemblies shall be properly identified by label as conforming to the requirements of this section.

(Prior code §  65-5.7)

15-12-150 Installation.

   Installation of fire-resistive door and shutter assemblies shall comply with the requirements of the following document: Protection of Openings in Walls and Partitions – NBFU-80 – 1939.

(Prior code §  65-5.8)

15-12-160 Opening protective assemblies – Windows.

   Windows required as opening protective assemblies shall comply with the provisions of Sections 15-12-170 to 15-12-250, inclusive.

(Prior code §  65-6)

15-12-170 Definition.

   Opening protective assemblies as applied to the requirements for windows shall include sash, frames, hardware and other accessories essential to the fire- resistive rating of the assembly.

(Prior code §  65-6.1)

15-12-180 Test procedure.

   Where fire-resistive windows are required by this Code, the fire-resistive values of such windows shall be determined by test procedure. The required time- temperature curve and method of testing shall be similar to that required for fire doors and shutters in Section 15-12-070. The duration of test on fire windows shall be not less than 45 minutes and shall include a hose-stream test.

(Prior code §  65-6.2)

15-12-190 Test assemblies.

   (a)   Test assemblies shall be truly representative as to material, workmanship of the construction and details, including installation, glass size, method of closing, hardware, trim and finish.

   (b)   The fire-resistive rating derived from the test shall be assumed to apply to all like assemblies smaller in dimension and area than the test specimen and to larger sizes not exceeding the area of the test specimen by more than 25 percent.

(Prior code §  65-6.3)

15-12-200 Conditions of acceptance.

   The fire-resistance test shall not be regarded as successful unless the following conditions are met:

   (a)   The test assembly shall have remained securely in the opening during the fire exposure period and during the hose-stream test, except that small fragments of glass dislodged from the exposed surface by the hose stream shall not be considered a weakness. The fastening of ventilators or movable sections shall have remained secure.

   (b)   The test assembly shall have withstood the fire-endurance test without passage of flame; and shall have withstood the fire-endurance and hose-stream tests without the dislodgement of an excessive proportion of the glass area. A loss of approximately ten percent shall not be considered excessive.

(Prior code §  65-6.4)
