UL991: Test for Safety-related Controls Employing Solid-State Device Introduction Scope These Requirements apply to controls that employ solid-state devices and are intended for specified safety-related protective functions. 这些要求适用于采用固态元件的控制并且用于与特定的与安全有关的保护功能上。 1．2 These requirements address the potential risks unique to the electronic nature of a control. Equipment or components employing an electronic feature shall also comply with the basic construction and performance requirements contained in the applicable end-product or component standard. These requirements are intended to supplement applicable end-product or component standards and are not intended to serve as the sole basis for investigating the risks of fire, electric shock, or injury to persons associated with a control. 这些要求陈述了电子类控制独特的潜在风险。具有电子特性的设备或元件应该也符合包含在适用终端产品或元件标准的基本结构和性能要求。这些要求是用来补充适用终端产品或元件标准。同时它不是唯一研究与控制相联的着火，电击，人身伤害风险的根据。 1.3 These requirements do not cover controls covered by end-product standards in which an electronic control investigation is specified. 这些要求没有覆盖终端产品标准包含的标准。在终端标准里，已经标明了电子控制的调查标准。 1.4 Sections 9-22 contain standardized test methods for investigating the performance of an electronic control when subjected to particular environmental stresses. The suitability of each test to a given control shall be determined by the end-product standard(s). Determination shall include an assessment of : a) Whether the control will be exposed to a particular environmental stress in its application, and b) Whether the response of the control t a particular environmental stress is relevant to its intended safety-related protective function in its application. 9-22部分包含了在特殊外界影响压力下研究电子控制的标准测试方法。 判定应该包含以下一个评估： a) 控制装置是否会在使用过程中曝露于特定的外界影响压力； b) 特殊外界影响压力引起的控制响应是否与它在应用时设定的安全相关的保护功能相关联。 2 Components 2.1 Except as noted in 2.2, a component of a product covered by this standard shall comply with the requirements for that component. 除了在2.2纪录外，本标准所覆盖的产品的元件应该符合该元件的要求。 2.2 A component is not required to
