The test assembly shall be subjected to an increasing superimposed load equal to not less than two times the superimposed design load. The test load shall be left in place for a period of 24 hours. The tested assembly shall be considered to have successfully met the test requirements if the assembly recovers not less than 75 percent of the maximum deflection within 24 hours after the removal of the test load. The test assembly shall then be reloaded and subjected to an increasing superimposed load until either structural failure occurs or the superimposed load is equal to two and one-half times the load at which the deflection limitations specified in Section 1710.3.2 were reached, or the load is equal to two and one-half times the superimposed design load. In the case of structural components and assemblies for which deflection limitations are not specified in Section 1710.3.2, the test specimen shall be subjected to an increasing superimposed load until structural failure occurs or the load is equal to two and one-half times the desired superimposed design load. The allowable superimposed design load shall be taken as the lesser of:
- The load at the deflection limitation given in Section 1710.3.2.
- The failure load divided by 2.5.
- The maximum load applied divided by 2.5.
Exterior windows and doors shall be labeled with a permanent label, marking, or etching providing traceability to the manufacturer and product. The following shall also be required either on a permanent label or on a temporary supplemental label applied by the manufacturer: information identifying the manufacturer, the product model/series number, positive and negative design pressure rating, product maximum size, glazing thickness, impact-resistance rating if applicable, Florida product approval number or Miami-Dade product approval number, applicable test standard(s), and approved product certification agency, testing laboratory, evaluation entity or Miami-Dade product approval.
1. Door assemblies installed in nonhabitable areas where the door assembly and area are designed to accept water infiltration need not be tested for water infiltration.
2. Door assemblies installed where the overhang (OH) ratio is equal to or more than 1 need not be tested for water infiltration. The overhang ratio shall be calculated by the following equation:
| OH ratio | = | OH Length/OH Height |
Where:
| OH length | = | The horizontal measure of how far an overhang over a door projects out from door surface. |
| OH height | = | The vertical measure of the distance from the door sill to the bottom of the overhang over a door. |
3. Structural wind load design pressures for window and door units other than the size tested in accordance with Section 1710.5.1 shall be permitted to be different than the design value of the tested unit provided such different pressures are determined by accepted engineering analysis or validated by an additional test of the window or door unit to the different design pressure in accordance with Section 1710.5.1. All components of the alternate size unit shall be the same as the tested or labeled unit.
i. Operable windows and doors rated in this manner shall comply with the following:
1. The frame area of the alternate size unit shall not exceed the frame area of the tested approved unit.
2. Shall vary from the tested approved unit only in width, height or load requirements.
3. Shall not exceed 100 percent of the proportional deflection for fiber stress of the intermediate members of the approved unit.
4. Shall not exceed 100 percent of the concentrated load at the juncture of the intermediate members and the frame of the approved unit.
Relocated5. Shall not exceed the air and water infiltration resistance of the tested approved unit.
6. Shall not exceed the maximum cyclic pressure of the tested approved unit when tested per TAS 201 and TAS 203 or ASTM E 1886 and ASTM E 1996, where applicable.
ii. Nonoperable windows and doors rated in this manner shall comply with the following:
1. The frame area of the alternate size unit shall not exceed the frame area of the tested approved unit.
2. Shall vary from the tested approved unit only in width, height or load requirements.
3. The maximum uniform load distribution (ULD) of any side shall be equal to the uniform load carried by the side divided by the length of the side.
4. The ULD of any member shall not exceed the ULD of the corresponding member of the tested approved unit.
5. The ULD of each member shall be calculated in accordance with standard engineering analysis.
6. Shall not exceed the air and water infiltration resistance of the tested approved unit.
7. Shall not exceed the maximum cyclic pressure of the tested approved unit when tested per TAS 201 and 203 or ASTM E 1886 and ASTM E 1996, where applicable.
4. For window and door units tested in accordance with Section 1710.5.2, structural wind load design pressures for window and door units other than the size tested in accordance with Section 1710.5.2 shall be permitted to be different than the design value of the tested unit provided such different pressures are determined by accepted engineering analysis or validated by an additional test of the window or door unit to the different design pressure in accordance with Section 1710.5.2. All components of the alternate size unit shall be the same as the tested unit. Where engineering analysis is used, the glass shall comply with Section 2403, and subsection i and ii of Exception 3, above.
5. Pass-through windows for serving from a single-family kitchen, where protected by a roof overhang of 5 feet (1.5 m) or more shall be exempted from the requirements of the water infiltration test.
Exterior window and door assemblies shall be tested in accordance with ASTM E 330 or TAS 202. HVHZ shall comply with TAS 202. Exterior window and door assemblies containing glass shall comply with Section 2403. The design pressure for testing shall be calculated in accordance with Chapter 16. Each assembly shall be tested for 10 seconds at a load equal to 1.5 times the design pressure (HVHZ shall comply with TAS 202).
- Door assemblies installed in nonhabitable areas where the door assembly and area are designed to accept water infiltration, need not be tested for water infiltration.
- Door assemblies installed where the overhang (OH) ratio is equal to or more than 1 need not be tested for water infiltration. The overhang ratio shall be calculated by the following equation:
| OH ratio | = | OH Length/OH Height |
where:
| OH Length | = | The horizontal measure of how far an overhang over a door projects out from the door's surface. |
| OH Height | = | The vertical measure of the distance from the door's sill to the bottom of the overhang over a door. |
3. Custom doors. Custom (one-of-a-kind) exterior door assemblies shall be tested by an approved testing laboratory or be engineered in accordance with accepted engineering practices.
