一般通风用气相空气净化介质和装置性能评定的试验方法.第3部分:用于室外空气处理的GPACD分类系统

[中文适用范围]： 本文件建立了 GPCD 的分类系统，该系统使用受当地城市污染源和/或远距离污染的室外空气向一般通风系统供应单程室外空气。 除了 ISO 16890-1 处理的颗粒污染之外，该分类系统还旨在帮助评估分子污染。 本文件规定了四种参考污染物，即臭氧、二氧化硫、二氧化氮和甲苯，由于它们与预期应用的相关性而用于分类。 本文件进一步规定了为每种污染物分配的三个责任级别，反映了该应用设备的典型性能范围。 由于参考污染物和关税水平的选择对于预期应用而言是特定且独特的，因此排除所有其他应用。 特别是，本文件不适用于再循环应用和/或处理室内污染源以及制药、微电子、核、国土安全和军事应用中的 GPCD。 [外文原描述]： This document establishes a classification system for GPACDs supplying single pass outdoor air to general ventilation systems using outdoor air polluted by local urban sources and/or long-distance pollution. The classification system is intended to aid in assessing molecular contamination in addition to the particulate contamination dealt with by ISO 16890-1. This document specifies four reference pollutants, i.e. ozone, sulphur dioxide, nitrogen dioxide and toluene, used for the classification due to their relevance to the intended application. This document further specifies three duty levels that are assigned for each pollutant reflecting the typical performance range of devices intended for the application. Since selection of reference pollutants and duty levels are specific and unique to the intended application, all other applications are excluded. In particular, this document does not apply to GPACDs in recirculation applications and/or dealing with pollution from indoor sources as well as pharmaceutical, microelectronic, nuclear, homeland security and military applications.
