Vehicular gates should be installed in accordance with ASTM F2200: Standard Specification for Automated Vehicular Gate Construction. For a copy, contact ASTM directly at
1.GENERAL REQUIREMENTS
1.1Gates shall be constructed in accordance with the provisions given for the appropriate gate type listed, refer to ASTM F2200 for additional gate types.
1.2Gates shall be designed, constructed and installed to not fall over more than 45 degrees from the vertical plane, when a gate is detached from the supporting hardware.
1.3Gates shall have smooth bottom edges, with vertical bottom edged protrusions not exceeding 0.50 inches (12.7 mm) when other than the exceptions listed in ASTM F2200.
1.4The minimum height for barbed tape shall not be less than 8 feet (2.44 m) above grade and for barbed wire shall not be less than 6 feet (1.83 m) above grade.
1.5An existing gate latch shall be disabled when a manually operated gate is retrofitted with a powered gate operator.
1.6A gate latch shall not be installed on an automatically operated gate.
1.7Protrusions shall not be permitted on any gate, refer to ASTM F2200 for Exceptions.
1.8Gates shall be designed, constructed and installed such that their movement shall not be initiated by gravity when an automatic operator is disconnected.
1.9A pedestrian gate shall not be incorporated into a vehicular gate panel or that portion of the adjacent fence that the gate covers in the open position.
2.SPECIFIC APPLICATIONS
2.1Any
2.2This specification shall not apply to gates generally used for pedestrian access and to vehicular gates not to be automated.
2.3Any existing automated gate, when the operator requires replacement, shall be upgraded to conform to the provisions of this specification in effect at that time.
3.VEHICULAR HORIZONTAL SLIDE GATES
3.1The following provisions shall apply to Class I, Class II and Class III vehicular horizontal slide gates:
3.1.1All weight bearing exposed rollers 8 feet (2.44 m), or less, above grade shall be guarded or covered.
3.1.2All openings located between 48 inches (1.22 m) and 72 inches (1.83 m) above grade shall be designed, guarded or screened to prevent a 4 inch
(102 mm) diameter sphere from passing through the openings anywhere in the gate, and in that portion of the adjacent fence that covers in the open position.
3.1.3A gap, measured in the horizontal plane parallel to the roadway, between a fixed stationary object nearest the roadway, (such as a gate support post) and the gate frame when the gate is in either the fully open position or the fully closed position, shall not exceed
(57 mm), refer to ASTM F2200 for Exception.
3.1.4Positive stops shall be required to limit travel to the designed fully open and fully closed positions. These stops shall be installed at either the top of the gate, or at the bottom of the gate where such stops shall horizontally or vertically project no more than is required to perform their intended function.
3.1.5All gates shall be designed with sufficient lateral stability to assure that the gate will enter a receiver guide, refer to ASTM F2200 for panel types.
3.2The following provisions shall apply to Class IV vehicular horizontal slide gates:
3.2.1All weight bearing exposed rollers 8 feet (2.44 m), or less, above grade shall be guarded or covered.
3.2.2Positive stops shall be required to limit travel to the designed fully open and fully closed positions. These stops shall be installed at either the top of the gate, or at the bottom of the gate where such stops shall horizontally or vertically project no more than is required to perform their intended function.
4.VEHICULAR HORIZONTAL SWING GATES
4.1The following provisions shall apply to Class 1, Class II and Class III vehicular horizontal swing gates:
4.1.1Gates shall be designed, constructed and installed so as not to create an entrapment area between the gate and the supporting structure or other fixed object when the gate moves toward the fully open position, subject to the provisions in the 4.1.1.1 and 4.1.1.2.
4.1.1.1The width of an object (such as a wall, pillar or column) covered by a swing gate when in the open position shall not exceed 4 inches (102 mm), measured from the centerline of the pivot point of the gate, refer to ASTM F2200 for exception.
4.1.1.2Except for the zone specified in Section 4.1.1.1, the distance between a fixed object such as a wall, pillar or column, and a swing gate when in the open position shall not be less than 16 inches (406 mm), refer to ASTM F2200 for exception.
4.2Class IV vehicular horizontal swing gates shall be designed, constructed and installed in accordance with security related parameters specific to the application in question.
