本文件规定了最低要求，并定义了适用于建筑物和工业生产厂防火用含氧气还原空气的固定式氧气还原系统的设计、安装和维护规范。它也适用于现有系统的扩展和修改。 本文件适用于使用富氮空气的氧气还原系统，其设计用于 在封闭空间内持续减少氧气。 注:如今，氮气是用于氧气还原的最合适气体。对于其他气体，这个 该文件可作为参考。交叉引用:EN 12094-1EN 50104ISO 7240（所有部分）EN 15004- 1:2008ISO 14520-1ISO 16000-8ISO 7010ISO 12100IEC 61508（所有部分）购买本文件时提供的所有当前修订版均包含在购买本文件中。

This document specifies minimum requirements and defines the specifications governing the design, installation and maintenance of fixed oxygen reduction systems with oxygen reduced air for fire prevention in buildings and industrial production plants. It also applies to the extension and modification of existing systems. This document applies to oxygen reduction systems using nitrogen-enriched-air which are designed for continual oxygen reduction in enclosed spaces. NOTE Nitrogen is, today, the most suitable gas to be used for oxygen reduction. For other gases, this document can be used as a reference.Cross References:EN 12094-1EN 50104ISO 7240 (all parts)EN 15004-1:2008ISO 14520-1ISO 16000-8ISO 7010ISO 12100IEC 61508 (all parts)All current amendments available at time of purchase are included with the purchase of this document.
