DJ S 38 4 : 202 6 vii Foreword The increasing frequency and intensity of hurricanes affecting Jamaica and the wider Caribbean underscore the need for reliable and standardized test methods to evaluate the performance of construction systems under extreme wind conditions. This standard has been developed to establish a uniform method for assessing the resistance of building materials, components, and assemblies to hurricane - induced impact forces . This standard is voluntary. Committee representation Related Documents This standard makes reference to the following: a) Testing Application Standard (TAS) 201 - 94 b) The Florida Building Code, Building Acknowledgement Acknowledgement is made to the International Council Code for permission to reproduce material from their standard.

DJS 384:2026 1 Jamaican Standard Method of Test for Hurricane Impact Resistance 1. Scope This standard outlines a method of test to determine whether specific building products — such as wall cladding, exterior windows, glazing, exterior doors, skylights, glass block, shutters, and other similar devices used to maintain the integrity of the building envelope — provide adequate resistance to windborne debris. 2. Normative references The Florida Building Code, Building TAS 3 01 3. Definitions For the purpose of this standard the following definition applies: 3.1 maximum deflection The maximum displacement of the specimen measured to the nearest 1/8 of an inch attained from the original position while the maximum test load is being applied. 3.2 permanent deformation The permanent displacement of the specimen measured to the nearest 1/8 of an inch from the original position to final position that remains after maximum test load has been removed. 3.3 specimen The entire assembled unit submitted for test, including but not limited to anchor - age devices, and structure to which product is to be mounted. 3.4 specimen failure A change in condition of the specimen indicative of deterioration under repeated load or incipient failure, such as cracking, fastener loosening, local yielding, or loss of adhesive bond. 3.5 test chamber An airtight enclosure of sufficient depth to allow unobstructed deflection of the specimen during pressure cycling, including ports for air supply and removal, and equipped with instruments to measure test pressure differentials.

DJS 384:2026 2 3.6 test load As determined by Sections 1625 and 1626 of the Florida Building Code, Building. NOTE 1 Such preparations may contain one or more types of alcohol, other active ingredients with excipients, and humectants. 4. Test specimen 4.1 All parts of the test specimen shall be full size, using the same materials, details, methods of construction and methods of attachment as proposed for actual use. The specimen shall consist of the entire assembled unit attached to a given type of structural framing of the building and shall contain all devices used to resist wind forces and windborne debris. When testing glazed products, the material used to make such glazed product windborne debris resistant (i.e., fillers, film and similar) shall be an integral part, factory applied, of such glazed product. In the case of windows, doors, and sliding glass doors, a pressure treated nominal 2 × 4 wood buck #3 Southern Pine shall be used for attachment of the specimen to the test frame/stand/chamber. Such wood bucks will become part of the approval. In the case of storm panels, they must be tested in worst case scenarios where attachments are directly to Concrete Masonry Units (CMU). Figure 1, on the following page, sho ws the basic three (3) configurations that shall be required; one per each of the three (3) required specimens. Each storm panel specimen shall consist of minimum three (3) panels. 4.1.1 Locking mechanisms shall be permanently mounted on the specimen. Such locking mechanism shall require no tools to be latched in the locked position. Devices such as pins shall be permanently secured to the specimen through the use of chains or wires which must be of corrosion resistant material. This section does not apply to specimens referenced in Section 2413 of the Florida Building Code, Building. 4.1.2 Products that are not categorized as means of egress/escape and are provided with more than one single action locking mechanism, shall be provided with permanently posted instructions on latching for high wind pressures. 4.1.3 S pecimen and fasteners, when used, shall not become disengaged during test procedure. 5. Apparatus: 5.1 The description of the apparatus is general in nature. Any equipment, properly certified, calibrated, and approved by the Authority Having Jurisdiction capable of performing this test within the allowable tolerance is permitted. 5.2 Major Components 5.2.1 Cyclic Wind — Pressure Loading As described in protocol DJS 383: 20XX. (Number of cycles and amount of pressure are indicated in Section 1625.4 and Table 1626 of the Florida Building Code, Building. Design wind pressure is to be determined by using Section 1620 of the Florida Building Code, Building.)

DJS 384:2026 3 5.2.1.1 Test Chamber — The test chamber, to which the specimen is mounted, shall be provided with pressure taps to measure the pressure difference across the test specimen and shall be so located that the reading is unaffected by the velocity of air supplied to or from the chamber. The specimen mounting frame (including the mullion and transom) must not deflect under test load in such a manner that the performance of the specimen will be affected. 5.2.1.2 Air System — A controllable blower, a compressed - air supply, an exhaust system, or reversible controllable blower designed to provide the required maximum air pressure difference across the specimen. The system shall provide an essentially constant air - pressure difference for the required test period. 5.2.1.3 Test temperature — The test shall be conducted at a test temperature range of 59 to 95°F (15 to 35° C). 5.3 Missile Impact 5.3.1 Timing System — The timing system, which is comprised of two, through - beam photoelectric sensors spaced at a known distance apart and used to start and stop an electronic clock, shall be capable to measure speeds accurate to ±2%. The speed of the missile sha ll be measured anywhere between the point where 90% of the missile is outside of the cannon, to the point where the missile is 30.5 cm away from the test specimen. The missile speed shall not be measured while the missile is accelerating. The through - beam photoelectric sensors shall be of the same model. The electronic clock shall be activated when the reference point of the missile passes through the timing system. The electronic clock shall have an operating frequency of no less than 10 kHz with a respons e time not to exceed 0.15 milliseconds. The speed of the missile shall be determined by dividing the distance between the two through - beam photoelectric sensors by the total time interval counted by the electronic clock. 5.3.1.1 Calibration of Timing Equipment — The timing system shall be calibrated and certified by the Authority Having Jurisdiction, at six - month intervals using one of the following methods: 1. Photographically, using a stroboscope, 2. Photographically, using a high - speed camera with a frame rate exceeding 500 frames per second, 3. Photographically, using a high - speed video camera with a frame rate exceeding 500 frames per second, or 4. Any other certified timing system calibration device used by an independent certified agency approved by this office. The calibration report shall include: the date of the calibration, the name of the agency conducting the calibration, the distance between the through - beam photoelectric sensors (if used), the speed of the missile as measured by the timing system, the speed of the missile as determined from the calibration system, and the percentage difference in speeds. The system shall be determined to be accurate if the speed of the mis sile measured by the timing system and the speed measured by the calibration system agree within 2%.

DJS 384:2026 4 5.1.2 Reserved 5.3.2.1 LARGE MISSILE — The large missile shall be a solid S4S nominal 2 × 4 wood buck of #2 surface dry Southern Pine. The weight of the missile shall be as specified in Section 1626.2.3 of the Florida Building Code, Building and shall have a length of not less than 213 cm (7 feet) and not more than 274 cm (9 feet). The missile shall be marked/ticked in dark ink at one - inch intervals on center and congruently numbered every three inches. A sabot shall be attached to the trailing edge of the missile to facilitate launching. The weight of the sabot shall not exceed 1.12 kg. The combined weight of the timber and sabot, which constitutes the missile, shall be between 4.08 kg (9 lb) and 4.31 kg (9.5 lb ). The missile shall be propelled through a cannon as described in Section 6.3.3 of this protocol. 5.3.2.2 When testing any specimen with more than one component, in addition to complying with the impacts required by Section 1626.2 of the Florida Building Code, Building the framing member connecting these components shall be impacted at one half the span of such member with the large missile at a speed indicated in Section 1626.2.4 of the Florida Building Code, Building. 5.3.2.3 Any specimen that passes the large missile impact test need not be tested for the small missile impact test if the specimen has no opening that a 0.48 cm (3/16 inch) sphere can pass through. 5.3.3 LARGE MISSILE CANNON — The large missile cannon shall use compressed air to propel the large missile. The cannon shall be capable of producing impact at the speed specified in Section 1626.2.4 of the Florida Building Code, Building. The missile cannon shall consist of four major components: a compressed air supply, a pressure release valve, a pressure gauge, a barrel and support frame, and a timing system for determining the missile speed. The barrel of the missile cannon shall consist of a 4 - inch inside diameter pipe and shall be at least as long as the missile. The barrel of the large missile cannon shall be mounted on a support frame in a manner to facilitate aiming the missile so that it impacts the specimen at the desired location. The distance from the end of the cannon to the specimen shall be 274 cm (9 feet) plus the length of the missile. 5.3.4 SMALL MISSILE — The missiles shall be propelled through cannon as described in Section 6.3.5 of this protocol. The small missile shall be launched in such a manner that each specimen shall be impacted over an area not to exceed 60.96 cm (two square feet) per impact as described in Section 1626.3.5 of the Florida Building Code, Building. Small missiles should be stainless steel or coated steel to avoid corrosion contamination. 5.3.5 SMALL MISSILE CANNON — A compressed air cannon shall be used that is capable of propelling missiles of the size and speed defined in Sections 1626.3.3 and 1626.3.4 of the Florida Building Code, Building. The cannon assembly shall be comprised of a compressed air supply and gauge, a remote firing device and valve, a barrel, and a timing system. The small missile cannon shall be mounted to prevent movement of the cannon so that it can propel missiles to impact the test specimen at points defined in Sectio n 1626.3.5 of the Florida Building Code, Building. The timing system shall be positioned to measure missile speed within 5 feet of the impact point on the test specimen.

DJ S 38 4 : 202 6 8 Standards Council The Standards Council is the controlling body of the Bureau of Standards Jamaica and is responsible for the policy and general administration of the Bureau. The Council is appointed by the Minister in the manner provided for in the Standards Act, 1969. Using its powers in the Standards Act, the Council appoints committees for specified purposes. The Standards Act, 1969 sets out the duties of the Council and the steps to be followed for the formulation of a standard. Preparation of standards documents The following is an outline of the procedure which must be followed in the preparation of documents: 1. The preparation of standards documents is undertaken upon the Standard Council’s authorisation. This may arise out of representation from national organisations or existing Bureau of Standards’ Committees of Bureau staff. If the project is approved it is r eferred to the appropriate sectional committee or if none exists a new committee is formed, or the project is allotted to the Bureau’s staff. 2. If necessary, when the final draft of a standard is ready, the Council authorises an approach to the Minister in order to obtain the formal concurrence of any other Minister who may be responsible for any area which the standard may affect. 3. The draft document is made available to the general public for comments. All interested parties, by means of a notice in the Press, are invited to comment. In addition, copies are forwarded to those known, interested in the subject. 4. The Committee considers all the comments received and recommends a final document to the Standards Council 5. The Standards Council recommends the document to the Minister for publication. 6. The Minister approves the recommendation of the Standards Council. 7. The declaration of the standard is gazetted and copies placed on sale. 8. On the recommendation of the Standards Council the Minister may declare a standard compulsory. 9. Amendments to and revisions of standards normally require the same procedure as is applied to the preparation of the original standard. Overseas standards documents The Bureau of Standards Jamaica maintains a reference library which includes the standards of many overseas standards organisations. These standards can be inspected upon request. The Bureau can supply on demand copies of standards produced by some national standards bodies and is the agency for the sale of standards produced by the International Organization for Standardization (ISO) members. Application to use the reference library and to purchase Jamaican and other standards documents should be addressed to: Bureau of Standards Jamaica 6 Winchester Road P.O.
