GageCast Fire Rating

Item 1

Gagecast has obtained a Class B Fire Rating as tested in accordance with ASTM E-84.   Refer to the attached IBC Flame Spread Table 803.4 (Item 3) to determine where a Class B product can be used.   Refer to Item 4 for use in elevator cab interiors.   Items 5a and 5b demonstrate the testing methods used and results received when Gagecast was tested at Southwest Research Institute’s Department of Fire Technology in San Antonio, Texas.

Item 2 – FLAME SPREAD/SMOKE DEVELOPMENT FOR WALL AND CEILING SPACES IN VARIOUS AREAS OF INTERIOR BUILDING SPACES

The above Flame Spread Table is part of the International Building Code (IBC). There are two main sets of criteria spelled out, one set for spaces that are equipped with a fire suppression sprinkler system, one set for spaces that are not equipped with a fire suppression sprinkler system. Another key element is the building occupancy type classification. These occupancy type classifications are defined in Chapter 3 of the IBC. As used throughout the code, the classification of an occupancy into a group is established by the requirements of this Chapter 3. The purpose of these provisions is to provide rational criteria for the classification of various occupancies into groups based on their relative fire hazard and life safety properties. This is necessary because the code utilizes group classification as a fundamental principle for differentiating requirements in other parts of the code related to fire and life safety protection. The flame spread requirements for rooms and enclosed spaces are all basically Class “B” (26-75) and Class “C” (76-200) values for spaces that are/are not equipped with a fire suppression sprinkler system. Smoke Development values for Class “A”, “B” and “C” flame spread ratings are all 0-450. Spaces that are equipped with a fire suppression sprinkler system are usually part of new “grounds-up” construction. Spaces that are not equipped with a fire suppression sprinkler system are usually part of remodeled space construction. Although the United States has adopted the IBC, local jurisdiction authorities may have written and adopted local “modifiers”.

NO RESTRICTIONS

NO RESTRICTIONS

NOTE: LOCAL JURISDICTIONS MAY ALTER THE ABOVE TABLE. VERIFY WITH LOCAL CODE OFFICIAL. 

a       Class C interior finish materials shall be permitted for wainscoting or paneling of not more than 1,000 square feet of applied surface area in the grade lobby where applied directly to a noncombustible base or over furring strips applied to a noncombustible base and fire-blocked as required by Section 803.1.

b       In vertical exits of buildings less than three stories in height of other than Group I-3, Class B interior finish for unsprinklered buildings and Class C interior finish in sprinklered buildings shall be permitted.

c          Requirements for rooms and enclosed spaces shall be based upon spaces enclosed by partitions. Where a fire-resistance rating is required for structural elements, the enclosing partitions shall extend from the floor to the ceiling. Partitions that do not comply with this shall be considered enclosing spaces and the rooms and spaces on both sides shall be considered one. In determining the applicable for rooms and enclosed spaces, the specific occupancy thereof shall be the governing factor of the group classification of the building or structure.

d       Lobby areas in A-1, A-2 or A-3 shall not be less than Class B materials.

e       Class C interior finish materials shall be permitted in places of assembly with an occupant load of 300 or less.

f        For churches and places of worship, wood used for ornamental purposes, trusses, paneling or chancel furnishing shall be permitted.

g       Class B material required where building exceeds two stories.

h       Class C finish materials shall be permitted in administrative spaces.

i        Class C interior finish materials shall be permitted in rooms with a capacity of four or less.

j        Class B materials shall be permitted as wainscoting extending not more than 48 inches above the finish floor in exit access corridors.

k       Finish materials as provided for in other sections of this code.

FLAME SPREAD/SMOKE DEVELOPMENT FOR VERTICAL SURFACES IN ELEVATOR CAB ENCLOSURES 

The elevator cab enclosure vertical surfaces flame spread and smoke development requirements are governed by the American National Standards Institute (ANSI) code ANSI A17.1. The International Building Code (IBC) by reference adopts this ANSI code as part of the overall IBC set of code requirements. Refer to 204.2a.1 (a) and (b) above to note that a Class “A” flame spread (0-25) is not required.

Item 5A – INTRODUCTION

This report presents the results of an ASTM E 84 test on a specimen submitted by the Client, tested at Southwest Research Institute’s (SwRI’s) Department of Fire Technology, located in San Antonio, Texas. The test is conducted in accordance with the procedure outlined in ASTM E 84-03, “Standard Test Method for Surface Burning Characteristics of Building Materials” (NFPA 255, ANSI/UL 723 and UBC 8-1).

This test method is applicable to exposed surfaces, such as ceilings or walls, provided that the material or assembly of materials, by its own structural quality or the manner in which it is tested and intended for use, is capable of supporting itself in position or being supported during the test period. The test is conducted with the material in the ceiling position.

The purpose of this test method is to determine the relative burning behavior of the material by observing the flame spread along the specimen. Flame Spread and Smoke Developed index are reported. However, there is not necessarily a relationship between these two measurements.

This standard should be used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions and should not be used to describe or appraise the fire-hazard or fire-risk of materials, products, or assemblies under actual fire conditions. However, results of the test may be used as elements of a fire-hazard assessment or a fire-risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard or fire risk of a particular end use. 

Test specimens are conditioned as appropriate in an atmosphere maintained between 68 and 78°F and 45 to 55% relative humidity. Immediately prior to the test, the specimen is mounted in the furnace with the side to be tested facing the test flame. Sometimes, because of the nature of the material undergoing testing, additional support (e.g. wire, wire and rods, rods, and/or bars) is used to ensure that the specimen will remain in position during the test. The use of supporting materials on the underside of the test specimen may lower the Flame Spread Index from that which might be obtained if the specimen could be tested without such support, and the test results do not necessarily relate to indices obtained by testing materials without such support.

The flame front position and light obscuration are recorded throughout the 10-minute test and used to calculate the Flame Spread and Smoke Developed indices. The temperature at 23 ft is also recorded. The Flame Spread and Smoke Developed indices reported herein are relative to the results obtained for mineral fiber- reinforced cement board and select grade red oak (moisture content between 6 and 8%). The mineral fiber- reinforced cement board is the calibration material used to obtain 0 values for Flame Spread and Smoke; red oak decks are used to obtain 100 values for Flame Spread and Smoke.

The results apply specifically to the specimens tested, in the manner tested, and not to the entire production of these or similar materials, nor to the performance when used in combination with other materials.

Two model building codes (2000 International Building Code®, Chapter 8 Interior Finishes, Section 803 Wall and Ceiling Finishes ; NFPA 5000, Chapter 10 Interior Finish , Section 10.3 Interior Wall or Ceiling Finish Testing and Classification) classify materials based on the Flame Spread and Smoke Developed indices. For reference purposes, the classification criteria are listed below:
