1.1 This specification defines performance-based and prescriptive-based methods of evaluating various classes of gates that are used for vehicular traffic and are to be automated. 1.2 Gate types addressed in this specification include horizontal slide gates, horizontal swing gates, vertical lift gates, vertical pivot gates and overhead pivot gates. 1.3 Gate types not listed in this specification will be subject to any applicable provisions contained in this specification. 1.4 Automated vehicular gates that do not comply with this specification shall be subject to independent evaluation for compliance with UL?325. 1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. This specification establishes the performance-based and prescriptive-based methods of evaluating various classes of automated gate constructions that are used for vehicular traffic. The gate types addressed in this specification include horizontal slide gates, horizontal swing gates, vertical lift gates, vertical pivot gates, and overhead pivot gates. Conversely, the four classes of gates covered here are as follows: Class I, a gate for the garage or parking area intended for use in a home of a one-to-four single family dwelling; Class II, a gate intended for use in a commercial location or building such as a multi-family
