标准摘要
[中文适用范围]： 本文件规定了用于燃气燃烧器、燃气器具和类似用途器具的多功能控制器（MFC）的安全、结构、性能和测试要求。 本文件适用于声明最大入口压力不超过 50 kPa (500 mbar)、标称连接尺寸不超过 DN 150、用于燃烧器或使用天然气、人造煤气或液化石油气等气体的设备的 MFC天然气（液化石油气）。 不适用于腐蚀性气体和废气。 MFC 由两种或多种功能组成，其中至少一种是机械控制，如相关控制标准中所规定。 本文件也适用于附件 K 中规定的燃烧器点火系统部件的结构和性能要求。 附件 K 中的要求和测试方法包括这些部件的可选型式测试和评估。 本文件适用于： ——水力燃气阀（见附件一）； ——过热安全装置（OSD）（见附件J）； ——燃烧器控制系统组件的可选要求（见附录 K）。 [外文原描述]： This document specifies safety, construction, performance and testing requirements of multifunctional controls (MFC) intended for use with gas burners, gas appliances and appliances of similar use. This document applies to an MFC with declared maximum inlet pressures up to and including 50 kPa (500 mbar) of nominal connection sizes up to and including DN 150 for use on burners or in appliances using gases such as natural gas, manufactured gas or liquefied petroleum gas (LPG). It is not applicable to corrosive and waste gases. An MFC consists of two or more functions, at least one of which is a mechanical control, as specified in the relevant control standards. This document is also applicable to construction and performance requirements for components of burner ignition systems as specified in Annex K. The requirements and test methods in Annex K include optional type testing and evaluation of these components. This document is applicable to: — water-operated gas valves (see Annex I); — overheating safety devices (OSDs) (see Annex J); and — optional requirements for components of burner control systems (see Annex K).
