Scope

本文件规定了使用二线本质安全以太网概念（2-WISE)的装置和系统的结构、标志和文件要求。
注：例如IEEE 802.3cg—2019中定义的用于二线以太网10BASE-T1L的物理层规范。
本文件适用于采用二线本质安全以太网概念的装置和系统。
2-WISE是高级物理层（APL)的概念，旨在简化APL段内元件和布线的本质安全参数的检验过程。这是通过定义APL端口的通用本质安全参数限值来实现的，根据特定的危险区域要求，并列出一组简明的分段设置规则。
2-WISE装置的部件可能通过GB/T 3836.1中列出的适用于预期危险场所EPL的任何防爆型式进行保护。在这些情况下，本文件的要求仅适用于装置的本质安全电路。
本文件与GB/T 3836.1、GB/T 3836.4、GB 3836.15或GB/T 3836.18配套使用。
