前言

本文件按照GB/T1.1—2020《標準化工作導則第1部分：標準化文件的結構和起草規(guī)則》的規(guī)

定起草。

本文件代替GB20128—2006《惰性氣體滅火劑》，與GB20128—2006相比，除結構調整和編輯性

改動外，主要技術變化如下：

a）更改了惰性氣體滅火劑的定義（見3.1，2006年版的3.1）；

b）更改了原料（組分）氣體中氬氣和二氧化碳的純度技術性能要求（見4.2.1表1，2006年版的

4.2.4表6）；

c）更改了原料（組分）氣體中氬氣和氮氣的水分含量技術性能要求（見4.2.1表1，2006年版的

4.2.4表6）；

d）增加了原料（組分）氣體中二氧化碳的總硫化物含量技術性能要求（見4.2.1表1）；

e）刪除了IG?01惰性氣體滅火劑的懸浮物或沉淀物技術性能要求（2006年版的4.2.1表1）；

f）增加了IG?01惰性氣體滅火劑的氧含量技術性能要求（見4.2.2表2）；

g）更改了IG?100惰性氣體滅火劑的氮氣含量、氧含量技術性能要求（見4.2.3表3，2006年版的

4.2.2表2）；

h）增加了IG?55惰性氣體滅火劑的水分含量和氧含量技術性能要求（見4.2.4表4）；

i）增加了IG?541惰性氣體滅火劑的水分含量和氧含量技術性能要求（見4.2.5表5）；

j）更改了原料（組分）氣體純度測定的試驗方法（見5.1，2006年版的5.2）；

k）更改了惰性氣體滅火劑含量測定的試驗方法（見5.2，2006年版的5.1）；

l）更改了原料（組分）氣體和惰性氣體滅火劑水分含量測定的試驗方法（見5.3，2006年版

的5.3）；

m）更改了原料（組分）氣體和惰性氣體滅火劑氧含量測定的試驗方法（見5.4.1，2006年版

的5.4）；

n）刪除了懸浮物或沉淀物測定的試驗方法（2006年版的5.5）；

o）增加了總硫化物含量測定的試驗方法（見5.5）；

p）更改了出廠檢驗項目（見6.1.1，2006年版的6.1.1）；

q）更改了盛裝惰性氣體滅火劑氣瓶的標志、充裝、包裝、運輸和貯存的要求（見第7章，2006年

版的第7章）。
