本文件代替GB/T27793—2011《抄取法無石棉纖維墊片材料》。與GB/T27793—2011相比，除

結(jié)構(gòu)調(diào)整和編輯性改動(dòng)外，主要技術(shù)變化如下：

a）更改了范圍（見第1章，2011年版的第1章）；

b）更改了要素分類（見4.1，2011年版的3.1）；

c）更改了標(biāo)記（見4.2，2011年版的3.2）；

d）刪除了卷材的長(zhǎng)度尺寸偏差（見2011年版的4.3.2）；

e）刪除了厚度尺寸偏差中“如果用戶有特殊要求時(shí)，按用戶要求執(zhí)行”（見2011年版的4.3.3）；

f）更改了物理機(jī)械性能指標(biāo)（見5.4，2011年版的4.4）；

g）更改了外觀檢查（見6.3，2011年版的5.3）；

h）更改了尺寸的測(cè)定方法（見6.4.2，2011年版的5.4.2）；

i）更改了測(cè)厚儀的要求（見6.14.1.8，2011年版的5.14.1.8）；

j）增加了氮?dú)庑孤┞试囼?yàn)方法（見6.15）；

k）更改了型式檢驗(yàn)（見7.1.2，2011年版的6.1.2）；

l）更改了組批原則（見7.2，2011年版的6.2）；

m）更改了抽樣方法（見7.3，2011年版的6.3）。
