1.1本规范描述了喷雾屏蔽材料的制造要求以及由该材料制成的喷雾屏蔽材料的制造和安装要求。 1.1.1章节 2 – 14 解决喷涂防护材料的制造要求。 附件A1 阐述了喷雾防护罩的制造和安装要求。 1.1.2 图1 显示了喷雾防护罩的典型结构。 无花果。2- 6. 展示在各种机械接头上安装防喷罩的方法。 1.2防护罩用于液体管道系统中的机械接头（法兰接头、螺栓接头等）周围，以防止易燃液体冲击热表面或因机械接头泄漏而导致的液体冲击电气配电盘和部件。 1.3以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。

1.1 This specification describes the manufacturing requirements for spray shield stock and the fabrication and installation requirements for spray shields made from that stock. 1.1.1 Sections 2 – 14 address the manufacturing requirements for the spray shield stock. Annex A1 addresses the fabrication and installation requirements for the spray shields. 1.1.2 Fig. 1 shows the typical construction of a spray shield. Figs. 2- 6 show methods of installation of a spray shield on various mechanical joints. 1.2 The shields are intended for use around mechanical joints (flanged, bolted unions, and so forth) in liquid piping systems to prevent the impingement of flammable liquid on hot surfaces or fluids onto electrical switchboards and components resulting from a leak in the mechanical joint. 1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
