BS EN 14543:2017规定了无烟道的设计、安全和标记要求以及试验方法 仅适用于室外或通风良好区域的露台加热器。这些设备仅适用于第4条中定义的第三类气体。本欧洲标准适用于标称热输入不超过17 kW（基于 总热值），最大入口压力为50 mbar:固定式或可移动式，包括构成可运输和可再充电液化燃料箱外壳的装置 石油气瓶。本欧洲标准不适用于装有风扇的电器，用于燃烧或燃烧 对流空气的循环。本欧洲标准不包括液化石油气及其相关产品的液化石油气容器 用于本欧洲标准涵盖的设备供气的调节器、管道和软管。 其他标准（EN 16129、EN 16436-1和 prEN 16436-2等）和国家法规。本欧洲标准未对该类型的热效率提出任何具体要求 但与燃烧有关的要求（这是一个安全问题）确保气体燃料 将有效燃烧。然而，信息性附录B中描述了测量性能的方法。交叉引用:EN 16617:2015EN 60335-2-102（IEC 60335-2-102:2004）模式13611:2015IEC 60335-1:2010EN 751-3:1996EN 161:2011+A3:2013IEC 60335-2-102:2004 Cons Ed 1-1EN 298:2012EN 437:2003+A1:2009IEC 60529:1989 Cons Ed 2-1EN 257:2010EN 1106:2010EN 751-1:1996EN 751-2:1996EN 60335-1（IEC 60335-2010）模式126:201260529:1991 EN 10226-1:2004EN 16129:2013EN 521:2006ISO 228-1:2000EN ISO 228-1（ISO 228-1:2000 AS）EN 461: 1999EN 16436-1:2014EN 10226-2:2005EN 449:2002+A1:2007EN 419-1:2009EN 416-1:2009购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS EN 14543:2017 specifies the design, safety and marking requirements and test methods for flueless patio heaters for outdoor or amply ventilated area use only.These appliances are for use exclusively with gases of the third family as defined in Clause 4.This European standard applies to appliances that have a nominal heat input not exceeding 17 kW (based on the gross calorific value), supplied with a maximum inlet pressure of 50 mbar:fixed or,movable, including those which comprise a housing for a transportable and rechargeable liquefied petroleum gas cylinder.This European standard does not apply to appliances equipped with a fan for either combustion or circulation of the convection air.This European standard does not cover LPG containers for liquefied petroleum gas, their associated regulator, tubing and flexible hoses used for gas supply of appliances covered by this European standard. Regulator, tubing and flexible hoses are covered by others standards (EN 16129, EN 16436-1 and prEN 16436-2, etc.) and national regulations.This European standard does not lay down any specific requirements for the thermal efficiency of this type of appliances, but the requirements relating to combustion, which is a safety matter, ensure that the gas fuel will burn efficiently. However a method to measure the performance is described in informative Annex B.Cross References:EN 16617:2015EN 60335-2-102(IEC 60335-2-102:2004)MODEN 13611:2015IEC 60335-1:2010EN 751-3:1996EN 161:2011+A3:2013IEC 60335-2-102:2004 Cons Ed 1-1EN 298:2012EN 437:2003+A1:2009IEC 60529:1989 Cons Ed 2-1EN 257:2010EN 1106:2010EN 751-1:1996EN 751-2:1996EN 60335-1 (IEC 60335-1:2010) ModEN 126:2012EN 60529:1991 EN 10226-1:2004EN 16129:2013EN 521:2006ISO 228-1:2000EN ISO 228-1 (ISO 228-1:2000 AS)EN 461:1999EN 16436-1:2014EN 10226-2:2005EN 449:2002+A1:2007EN 419-1:2009EN 416-1:2009All current amendments available at time of purchase are included with the purchase of this document.
