    General Product Control FAQ's


    When is the small missile test required?

    When prior to impact the specimen has an opening that a 3/16" sphere can pass, and this opening is perpendicular to the trajectory of the missiles being shot. Also, it is required for products to be installed above 30 feet in elevation and are not to require any protection device.


    When the small missile test is required after the large missile test, do you require a new specimen for the small missile test?

    No. The small missile test is performed on the same specimen.


    Do the small missiles have to be fired all at once?

    Yes, all 10 at once at the required speed for which only the speed of one has to be measured.


    Where do you aim the small missiles when they are required after the large missile impact test?

    You aim them at the same area as where the large missile impacted; this being the center of the specimen and 6 inches from one corner. Also, Ordinance 93-141 requires a third small missile impact "distributed uniformly over a two square foot area located at the center of the long dimension of the specimen near the edge".


    What is the 3/16" opening criteria specified in TAS201-94 Section 6.3.2.3?

    This applies to products that in their original state have openings of this dimension prior to being impacted by the large missile test. This criteria is for products that have a 3/16" opening perpendicular to the missile's trajectory. For example a mesh-like shutter device, etc.


    Does a specimen fail if the small missile goes through?

    Yes.


    When performing a static loading per TAS202-94 and a plastic filament is needed for air leakage, can you load the specimen to +0.5 test & release, then +1.0 test & release, and then -0.5 test & release, then -1.0 test & release?

    Yes provided all necessary measurements are recorded.


    What is the large missile failure criteria?

    A rupture in the specimen with dimensions greater than 1/16" by 5" per Ordinance 93- 141, constitutes a failure. For storm shutters, a separation as described in question 55 is allowed.


    What is the failure criteria for a glazed product when using the large missile test?
    The failure criteria are as stated in Ordinance 93-141, which states "an opening greater than 1/16" by 5" where air can pass". Note: If the opening is not evident upon impact but it is evident upon completion of the cycling, the specimen passed the impact but failed the cycling.

    Do soffits have to pass the impact test?

    No.


    Do all of the tests have to be recorded on video?

    Yes.


    Does the entire test of cycling have to be recorded on video?

    Only if you want, but it is encouraged. If you do not record the entire test, you must show at least the first 3 minutes and the last 3 minutes of this test.


    Does the air infiltration tests have to be performed before the water infiltration test?

    Yes.


    Can the large missile cannon be fired at a vertical angle to compensate for the missile drop causing a perpendicular impact to the specimen?
    Yes, the front of the barrel can be shimmed to cause a perpendicular impact to the specimen.

    Can the structural load test, for products that are required to be mounted on CBS block, be performed on a wooden buck?

    Yes, when the product is impact resistant. Else, it needs to be tested on CBS.


    What is the sequence for testing TAS202-94 when loading the specimen?

    The required "positive" design pressures are run first and then the "negative" design pressures.


    I have a product that has a large variety of applications as far as size and mounting locations are concerned. Do I have to test all of them for stati

    In lieu of testing all the applicable cases, comparative analysis may be allowed, provided three (3) specimens are tested to positive failure, and three (3) specimens are tested to negative failure. From the three (3) tests, in the direction which proves weakest, curves are derived. If the ultimate load for any of the three (3) specimens tested varies more than 20% from the average, three additional tests shall be made and all tests considered in determining the average ultimate load. An average of the three (3) curves is then taken. Two (2) points on the curve are chosen, for which two (2) additional specimens are to be tested in order to prove these points. The results from these last two (2) tests are to be within the 20% margin previously mentioned in order to accept the comparative analysis for that product. This procedure applies only to shutters.


    Will tests for my product be accepted if the lab, or I do not notify Miami Dade County of the test?
    No.  If we do not have notification of the test 7 days prior, your test is not valid.

    Do all products tested under the fatigue loading sequence have to have a recovery of at least 90%?

    No. This only applies to cladding.


    How long is a Certified testing laboratory's report valid before being submitted for product approval in Miami Dade County?

    The laboratory's report shall not be older than six (6) months at the time it is submitted for product approval.


    How many specimens have to be tested in Protocol TAS202?
    If the product is impact resistant (TAS201 & TAS203 will be performed).  One (1) specimen to TAS202 is allowed.  If the product is non-impact 3 units are required.

    May the 2-mil polyethylene be substituted for a thicker one?

    2-mil polyethylene film must be used all of the time. You may "only" use 4 mil when pressures exceed 150 psf.


    May the laboratory's client record the video and submit it as the required video for Miami Dade County Product Approval?

    The client may do the required video of the testing for Dade County submission provided the laboratory accepts the video as submittal with the lab report.


    When the forced entry test is required and I am not testing for impact, do all three specimens tested for protocol TAS202 have to undergo the forced entry test?

    Yes.


    What is the agreed sequence of testing for products that have to meet the water requirements of protocol TAS202?

    First, test the air infiltration. Second, load the product to 0.5 x test load. Third, load to design pressure. Fourth, test the water at it's corresponding pressure. Lastly, test to full test load.


    When testing the three required specimens and a failure occurs in the last specimen, do I have to re-test three new specimens?
    An additional fourth specimen in the same conditions as the one that failed is allowed.  If the specimen failed in impact, the fourth specimen tested must be exactly the same and the impact locations are in the same locations as the one that failed.  If the fourth fails, a fifth specimen will only be allowed if the specimen is changed (e.g. the anchoring spacing, the mounting for that condition, or extrusion for that particular mount).  As a result, if the product fails on a mounting condition and all of the mountings are the same you are allowed only a fourth specimen.  If you have different mountings and one fails, it can be re-tested with a fourth specimen, and then a fifth if that mount is changed or modified.  For glazed products failing in the glazed section, a fourth specimen is all that will be allowed; if you change the glass a new set of three would have to be tested.  Three specimens are required to pass.

    What is the specified dimension and type of 2x4 required for the large missile impact test in Protocol TAS201?

    The type of wooden 2x4 shall be as specified in PA201 section 6.3.2.1 (No. 2 Southern Yellow Pine S4S). The length shall be not less than 6 feet and shall not exceed 8 feet.


    Are we allowed a 5-inch radius circle where the large missile can impact in, for all of the specified locations of impact?

    No. The impacts that clearly state to hit the "meeting rail", "joint", or "valley" must impact in those locations. A 5-inch radius must not be used in those impacts.


    How does the metallurgical testing get done if the laboratory testing the product does not have the capabilities to perform the metallurgical test?

    The laboratory, performing the system tests, is responsible to contract a Miami Dade County Approved laboratory that can perform the test.  The lab is to send the product for the metallurgical testing; not the product manufacturer.  The metallurgical laboratory shall reference the product test number on the metallurgical test report.


    Does the approved engineer listed with the certified testing laboratory have to be present during the execution of a given test?

    Yes.  If the listed engineer is not present during the test, that test shall not be accepted.


    Where deflection measurements should be taken on a sample being tested to TAS202?

    Measurements are to be taken at locations where the maximum deflection occurs.  This may differ from product to product.  If a sample's deflection is measured at a point where there is another point deflecting more, an additional dial indicator shall be placed at that new location.


    Can a group of manufacturers of a particular product get together with the purpose of testing for approval?

    Yes. A request for such testing must be made to BCCO prior to the testing (use the special project/hourly rate application).  The intent of this procedure is to try to help manufacturers of the same products curtail the cost of testing.


    If when testing TAS202 a failure occurs in any of the various test procedures of the protocol, does the entire sequence of testing need to be repeated on a new or revamped sample?

    Yes, the whole testing procedure will need to be repeated.  If the specimen fails to meet any of the procedures within TAS202, the specimen has failed said protocol.


    What is the understanding of the allowed 5" radius mentioned in the South Florida Building Code section 2315.1(e)?
    The 5" radius was established as a tolerance. The referenced section clearly states that the missile is to impact within the described circle. Should a missile fail to impact the sample "within" the prescribed circle, the shot will not be accepted and the shot is to be repeated. The following are acceptable and unacceptable shots depicted as 1 and 2, respectively. Locations specified for impact such as but not limited to meeting rails, mullions, valleys, and seams do not have an established tolerance. Therefore, the specified location is to be impacted.

     


    What are acceptable ways of qualifying different glass-type manufacturers into my glazed impact-resistant product Notice of Acceptance?

    The following are some acceptable ways:

         1. From the three required impact and cycle samples, you can provide a different manufacturer's glazing into each of the samples. 

    The procedure followed is that the lower design pressure qualified from the three is what will be reflected on the approval.  If one of the three specimens should fail the tests, three specimens of that type of glazing are to be tested to qualify that glass on the given system.

    The determination of which unit or units are to undergo TAS202 testing will depend on the variations of glass type and thickness. 

    Determination and evaluation of a planned test procedure should be presented to BCCO in the form of a proposal

        2.  If you already have a Notice of Acceptance and you wish to qualify a different impact resistant glazing, you are required to show three samples passing the complete set of TAS201 and TAS203 testing, and testing to TAS202 will depend on the variations of glass type and thickness.  You can take advantage in this type of testing by following case #1 above.


    How should different levels of reinforcement be addressed in the testing of glazed products?

    The approach is to determine the largest level of reinforcement, which typically corresponds to the highest pressure for the system.  Arrange the units in decreasing level of reinforcement and projected/applicable design pressure. 

    If non-impact resistant, the following applies:
    Test three units of the highest level of reinforcement to the highest design pressure for the system as required in TAS202.  These units are to undergo all of the requirements of TAS202.  Then test one additional sample for each decreased level of reinforcement and to the corresponding determined design pressure.  Each of these additional specimens is to be tested to the structural requirements of TAS202, and depending if other parts of the system are decreased (such as sill heights or glass thickness) the water test will also apply. 
    If impact resistant, the following applies:
    Test one unit of the highest level of reinforcement to the highest design pressure for the system as outlined in TAS202.  This unit is to undergo all of the requirements of TAS202.  Then test one additional sample for each decreased level of reinforcement and to the corresponding determined design pressure.  Each of these additional specimens is to be tested to the structural requirements of TAS202, and depending if other parts of the system are decreased (such as sill heights or glass thickness) the water test will also apply.

    Test three units of the highest level of reinforcement to the highest design pressure for the system as required in TAS201 and TAS203.  Then test one additional sample for each decreased level of reinforcement to the corresponding determined design pressure following TAS201 and TAS203.


    How does a laboratory that tests impact resistant glass report the composition/description of the material used in the glazing?

    The following are some acceptable ways:

         1. From the three required impact and cycle samples, you can provide a different manufacturer's glazing into each of the samples. 

    The procedure followed is that the lower design pressure qualified from the three is what will be reflected on the approval.  If one of the three specimens should fail the tests, three specimens of that type of glazing are to be tested to qualify that glass on the given system.

    The determination of which unit or units are to undergo TAS202 testing will depend on the variations of glass type and thickness. 

    Determination and evaluation of a planned test procedure should be presented to BCCO in the form of a proposal

        2.  If you already have a Notice of Acceptance and you wish to qualify a different impact resistant glazing, you are required to show three samples passing the complete set of TAS201 and TAS203 testing, and testing to TAS202 will depend on the variations of glass type and thickness.  You can take advantage in this type of testing by following case #1 above.


    Can comparative analysis be included on one Notice of Acceptance (NOA) for impact and non-impact glazed products?

    No.  Non-impact resistant products and impact resistant products must obtain separate Notice of Acceptance (NOA).


    Can comparative analysis be performed on an impact resistant glazed product?
    Yes.  Comparative analysis can be performed by conforming to the provisions in the  Florida Building Code Section 2411.3.2.5 or 2411.3.2.6 as applicable.

    Can the spacing of anchors of a tested unit be altered when the approval documents are prepared?

    No. The maximum spacing allowed in the approval documents will be limited to the smallest spacing between anchors used in the test. Load verification of anchors shall be based on the largest anchor load transferred in the tested unit.


    Can a wood screw or sheet metal screw tested in wood under shear conditions be substituted with a self taping concrete anchor of the same or greater root diameter?

    Yes, provided the engineer has listed said anchor in the approval document and said anchor has a current NOA or published literature for the anchor.


    When using ASTM E1300 how does Miami-Dade County address glass plate dimensions smaller than those covered within the boundaries of each “Glass Thickness Selection Chart?

    This is the area where the points corresponding to smaller glass plate sizes are located on a graph, forming a triangle between the discontinued lines of Aspect Ratio 1 and 5 and the vertex or origin of the chart.Impact Resistance

     

     

    The graph will be extended to the vertex and glass plate sizes lying inside this area can be qualified for the pressure corresponding to the maximum pressure tested or in a simplified comparative analysis corresponding to the last design pressure curve graphed in the standard.

     

     

     

     

     


    When using ASTM E1300 how does Miami-Dade County address irregular shapes other than rectangular glass units?

    The design pressure of an irregular shape glass unit shall be that corresponding to the rectangular shape circumscribing the irregular shape. The design pressure of a rectangular glass unit is also applied to any irregular shape glass unit inscribed inside that rectangle. Please note this does not change the requirements of testing shapes to qualify shapes.
    Irregular Shapes


    When using ASTM E1300 how does Miami-Dade County address aspect ratios greater than 5?
    Aspect ratio greater than 5 can be approved provided that one specimen of the greatest aspect ratio and size is tested to the corresponding pressure in ASTM E1300 with an aspect ratio of 5. This corresponds to glass plate sizes that fall in the shaded area of the graph shown below. If approval of such aspect ratio sizes are sought these are to be considered when developing a test plan.
    Ratios greater than 5

     


    When using ASTM E1300 how does Miami-Dade County address unequal thickness in lites of laminated glass units?

    Add the two glass plate thickness’ to select the appropriate “Glass Thickness Selection Chart” listed in table 5 of ASTM E1300.


    When using ASTM E1300 how does Miami-Dade County address unequal heat treatment in lites of laminated glass units?
    Aspect ratio greater than 5 can be approved provided that one specimen of the greatest aspect ratio and size is tested to the corresponding pressure in ASTM E1300 with an aspect ratio of 5. This corresponds to glass plate sizes that fall in the shaded area of the graph shown below. If approval of such aspect ratio sizes are sought these are to be considered when developing a test plan.
    Ratios greater than 5

     


    When using ASTM E1300 how does Miami-Dade County address unequal thickness in lites of laminated glass units?

    Use the lower performing of the two glass heat treatments to select the appropriate "Glass Type (GT) Factor" in Table 1 of ASTM E1300.


    What are the criteria for un-supported jambs (free jambs) for approval in a product?

    Un-supported (free jambs) vertical members must comply with FBC section 1613.1 (5) for deflection requirements and must not exceed the allowable stress for the type of material used.


    What is the maximum end gap allowed between un-supported jamb and substrate?

    The end gap can not be specified as un-limited. The end gap must be limited either as tested or by the sealant (caulking) manufacturer's joint performance capabilities and recommendations. Design consideration must also be given to weathering, water proofing, fire propagation, material expansion, compatibility, working joints and sealant performance.
