IEC 61892-7:20 19规定了移动和固定海上装置（包括管道、泵送或“清管”站、压缩机站和单浮标系泊）危险区域分类和电气设备选择以及危险区域安装的要求，用于海上石油工业的钻井、生产、住宿、加工、储存和卸载目的。 它适用于所有装置，无论是永久的、临时的、可移动的还是个人的，适用于交流装置和直流装置，没有任何电压等级限制。参考的设备标准可能会给出电压电平限制。 本文件基于IEC TC 31制定的有关区域分类和危险区域安装要求的国际标准要求，并给出了移动式和固定式海上装置安装的附加要求。本文件规定了以下要求: -区域分类， -电气系统， -电气设备的选择， -电缆和布线系统， -通风， -电池室的通风要求，以及 -检查、维护、修理和大修。 本文档提供了以下主题的信息: -气体检测系统，以及 -环境温度极低的电气装置。 本文件不适用于 -用于医疗目的的固定设备， -油轮的电气装置，以及 -控制电气设备产生的点火源以外的点火源。 这第四版取消并取代了2014年出版的第三版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更:a)文件已被完全重写。尽可能参考IEC 60079-14和IEC TC 31中的其他相关标准；仅给出了偏离危险区域装置一般要求的海上装置的要求； b)关于气体检测的要求已转移到信息性附件中； c)有关紧急停机（点火源控制）的要求已转移至IEC 61892-1。

IEC 61892-7:2019 provides requirements for hazardous area classification and selection of electrical equipment and installation in hazardous areas in mobile and fixed offshore units, including pipeline, pumping or "pigging" stations, compressor stations and single buoy moorings, used in the offshore petroleum industry for drilling, production, accommodation, processing, storage and offloading purposes.
It applies to all installations, whether permanent, temporary, transportable or personal, to AC installations and DC installations without any voltage level limitation. Referenced equipment standards may give voltage level limitations.
This document is based on the requirements of International Standards developed by IEC TC 31 regarding area classification and requirements as to installations in hazardous areas and gives additional requirements for installations on mobile and fixed offshore units.
This document specifies requirements such as those concerning
– area classification,
– electrical systems,
– selection of electrical equipment,
– cables and wiring systems,
– ventilation,
– ventilation requirement for battery compartments, and
– inspection, maintenance, repair and overhaul.
This document gives information on topics such as
– gas detection systems, and
– electrical installations in extremely low ambient temperatures.
This document does not apply to
– fixed equipment for medical purposes,
– electrical installations of tankers, and
– control of ignition sources other than those created by electrical equipment.
This fourth edition cancels and replaces the third edition published in 2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the document has been completely rewritten. References are, to the extent possible, made to IEC 60079-14 and to other relevant standards, as appropriate, from IEC TC 31; only requirements concerning offshore installations that deviate from the general requirements for installations in hazardous areas are given;
b) requirements as to gas detection have been transferred to an informative annex;
c) requirements concerning emergency shutdown (ignition source control) have been transferred to IEC 61892-1.
