5.1 The Intended Use of This Guide is to identify the specific functions and qualities desired of a pickleball fence and offer recommendations on how to achieve them with a chain link fence for different types of pickleball courts.5.2 The Primary Function of a Pickleball Court Fence is to keep pickleball balls in and uninvited traffic out. It also serves as a barrier to prevent players from colliding with fixed objects and spectators. It also prevents players from running onto irregular or slippery surfaces or into dangerous adjacent areas. Fences need to respond to secondary functional requirements, including: spectator viewing, screening the court from wind and visual distractions outside the court, and being as open and welcoming as security conditions permit. In cases where security or dangerous adjacent conditions are an issue, a uniformly high type of enclosure can still be called for, but in most cases, pickleball fences are a variety of heights and may accommodate lights, shade shelters, gates for players and maintenance, and can have completely open (no fence) portions of the perimeter that lead to decks, grandstands, or landscaping1.1 The purpose of this guide is to inform the builder, designer, facility manager, or owner, or a combination thereof, of a pickleball court or facility about the many details and features of pickleball court fence. It focuses on what to consider when designing a pickleball fence, offers some recommendations, and points the user to where they could find additional useful information regarding the design, construction, and maintenance of pickleball courts.1.2 Units—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.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 Electric security fences, in view of their high-deterrent impact, are a safe method to reduce security costs or enhance existing security. They are deployed in a wide variety of environments and geographies. In particular, electric security fences are used to decrease the need for security guards and other security systems.4.2 This practice provides information to users and manufacturers of electric security fences, filling a void.4.3 International standards exist at the International Electrotechnical Commission (IEC) and the British Standards Institution (BSI) (see Section 2) that cover some aspects of these systems.4.4 A standard issued by Underwriters Laboratories (UL) (UL 69) covers electric-fence controllers to be used on lighting or line circuits in accordance with the National Electrical Code, NFPA 70. However, UL 69 covers specifically electric-fence controllers used only for the control of animals. Its requirements cover portable and permanently mounted electric fence controllers with peak-discharge or sinusoidal-discharge output for indoor or outdoor use, including battery operated controllers intended to operate from battery circuits of 42.4 V or less, line-operated controllers intended to operate from circuits of 125 V or less, combination controllers intended to operate from either a battery or a line circuit, and photovoltaic module battery operated controllers. The scope states that the requirements of UL 69 do not cover electric fence controllers for the continuous (uninterrupted) current type or intermediate equipment, such as a converter, a rectifier, or the like, that is sometimes used between the primary source of supply and an electric fence controller and is investigated only as part of a complete controller. UL 69 also states that the requirements do not cover electric fence controllers for use with electrified security fences.4.5 In contrast to UL 69, this practice specifically addresses the use of electric security fences in a commercial application.NOTE 1: Extensive research on the safety of pulsed electrical devices, which are used in electric fence controllers, is found in work by Amit Nimunkar and John Webster.6 This research provides background on the safety of electric security fences and is of value to those wishing to understand the basic science behind these systems.1.1 The purpose of this practice is to provide advice for the selection and use of electric security fences to deter, detect, and delay an unauthorized breach of the perimeter in a commercial application.1.2 Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. The tolerance on physical dimensions is ±10 % unless otherwise specified.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
