As we continue our recovery and cleanup efforts, please visit the Emergency website for the latest information on openings and closings in Miami-Dade County.
During a large missile test if a rupture of 3/16 inch occurs, the specimen failed the large missile test because rupture of dimensions greater than 1/16" by 5" constitutes a failure per Ordinance 93-141.
- Garage doors with vents that have openings larger than 3/16" do not have to be tested for small missile impact.
- Garage doors have to be cycled in both positive and negative directions.
- When testing roll garage doors, the size specimen tested shall match the largest size sought for approval foresees installing or wants product approval.
- Small ventilators less than 60in2 can be installed on garage doors without undergoing the impact test requirements. Any larger vents will have to be tested with the door.
- After testing a garage door that has 2' tall panels at 8' high, approval for taller doors (10', 12' and 14') can be obtained only if the design of the door does not incorporate vertical supporting members.
- A removable beam behind the garage door for the needed structural support will be allowed as meeting the intent of permanently attached if a cable is attached from the beam to the door.
- You may test a full garage door without a glazed panel and cycle it 671 times. You then may test a "single glazed panel" for the 9000 cycles and use it in the "whole" door system.
- Approval of Roll-up and Sectional doors is limited to three (3) times the height of the door tested. This is only applicable when the tested door does not have the top or bottom ends restricted. If the tested door has locks that engage on the floor, or vertical reinforcements, this does not apply; in this case the door shall be approved for the height tested.
Chambers for garage doors
In order for the garage door to slide on after testing, the chamber should have sufficient depth to contain the curve portion of the track. A removable opening can be used at the top rear of the chamber where the top tracks can be installed after testing to roll the door up and down. See figure below.
Overhead garage door impact locations
- The impact locations for overhead garage doors without struts are the same as for shutters but rotated by 90 degrees; see question SH13.
The impact locations for overhead garage doors with vertical struts, the impacts are as shown below.
Roll-up garage door impact locations
For roll-up garage doors only the center and a corner are required, but if the application is as shown below where the slats do not push up against the entire opening the roll drum must also be impacted.
Submitting garage door variations
Only one design (material or pattern) is accepted per application.
A. You may submit two different thickness' of the same design under one application by testing the thinner material. The approval of the thicker material will be based on the results of the thinner material tested.
B. You may submit two different spans of the same design under one application by testing the longest span. The approval of the short span will be based on the results of the longest span tested.
Each set of uniform static air test (TAS202), performed on a specific model, series, or type of door requires one application.
If a group of doors of the same design, material and pattern are being tested, it is only necessary to impact (TAS201) and cycle (TAS203) the thinner (weakest) door with the highest pressure. The satisfactory result of these tests will qualify the group of doors of the same design, material and pattern.
Procedure for testing garage doors to TAS202
Apply 5 percent test load to remove the ''play'' of the door. Return pressure to 0 and set all deflections dials to 0.
Bring pressure to 1/2 test load and record deflection.
Remove all loads and read deformation if any. Recovery at this point shall be 95-100 percent.
Bring pressure to test load and record deflection.
Remove all load and record deformation permanent set). Recovery shall be at least 80 percent. Repeat the above in the negative direction in the same manner. Perform this test on as many samples required. The door shall be raised to an open position after the test. The laboratory must report if the door was operable or not after the test.
Procedure for reporting and installing garage door specimens to the test chamber
To begin with, only those anchors and fasteners that were tested shall be approved.
For Roll-Up Doors:
Specimen 1 test to TAS201 & TAS203 on 2000 psi concrete column on both sides and qualify two types of anchors.
Specimen 2 test to TAS201 & TAS203 on A36 steel column on both sides and qualify two types of fasteners.
Specimen 3 test to TAS201 & TAS203 on C-90 masonry block with 2000 psi grout column on both sides and qualify two types of anchors.
For Sectional Doors:
Specimen 1 test to TAS201 & TAS203 on 2"x6" or larger PT#3 Southern Pine wood buck on both sides and qualify two types of anchors.
Specimen 2 test to TAS201 & TAS203 on C-90 masonry block with 2000 psi grout column on both sides and qualify two types of anchors.
Specimen 3 test to TAS201 & TAS203 on 2000 psi concrete column on both sides and qualify two types of anchors.
In both cases mentioned above, each test will qualify one structural substrate application and two types of fasteners/anchors. Other types of substrates may require additional testing.
When down sizing any of the mentioned doors, the spacing of the anchors shall never exceed that which was tested.
The requirements of TAS202 can be performed in any type of substrate mentioned above and with any of the fasteners/anchors used for TAS201 & TAS203.
The test report shall describe the anchor/fastener type, location, embedment, spacing, type of column substrate and specification, etc. Calculations verifying the anchor/fastener used and recommended method of installing 2'x6" or larger buck to concrete/masonry block shall be submitted.
Please note that if you wish to only receive approval for one column substrate, then the three required tests for TAS201 and TAS203 shall be performed on that substrate. You may still qualify different anchors/fasteners on said column substrate.Back to Top Page Last Edited: Mon Nov 19, 2018 4:23:28 PM
