1.1 本规程的目的是为电子安全围栏的选择和使用提供建议，以阻止、检测和延迟商业应用中未经授权的周边违规行为。 1.2 单位- 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。物理尺寸公差为±10 % 除非另有规定。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 鉴于电动安全围栏具有很高的威慑作用，它是一种降低安全成本或增强现有安全性的安全方法。它们部署在各种环境和地理位置。特别是，使用电动安全围栏来减少对保安和其他安全系统的需求。 4.2 这种做法为电动安全围栏的用户和制造商提供了信息，填补了空白。 4.3 国际标准由国际电工委员会（IEC）和英国标准协会（BSI）制定（见第节） 2. )这涵盖了这些系统的一些方面。 4.4 美国保险商实验室（UL）（UL 69）发布的标准涵盖了根据国家电气规范NFPA 70在照明或线路电路上使用的电动围栏控制器。然而，UL 69专门涵盖了仅用于控制动物的电动围栏控制器。其要求包括便携式和永久安装的带峰值电压的电动围栏控制器- 室内或室外使用的放电或正弦放电输出，包括拟从42.4 V或以下的电池电路操作的电池操作控制器、拟从125 V或以下的电路操作的线路操作控制器、拟从电池或线路电路操作的组合控制器，以及光伏模块电池操作控制器。该范围规定，UL 69的要求不包括用于连续（不间断）电流型或中间设备的电子围栏控制器，例如转换器、整流器等，这些设备有时用于一次电源和电子围栏控制器之间，并且仅作为完整控制器的一部分进行研究。 UL 69还规定，这些要求不包括与带电安全围栏一起使用的电动围栏控制器。 4.5 与UL 69不同，本规程专门针对商业应用中电动安全围栏的使用。 注1: 阿米特·尼蒙卡（Amit Nimunkar）和约翰·韦伯斯特（John Webster）对用于电动围栏控制器的脉冲电气设备的安全性进行了广泛的研究。 6. 本研究提供了电气安全围栏的安全背景，对希望了解这些系统背后的基础科学的人有价值。

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. ====== Significance And Use ====== 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.
