前言

本文件按照GB/T1.1—2020《標(biāo)準(zhǔn)化工作導(dǎo)則第1部分：標(biāo)準(zhǔn)化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)

定起草。

本文件代替GB/T10422—2002《燒結(jié)金屬摩擦材料橫向斷裂強(qiáng)度的測(cè)定》，與GB/T10422—

2002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）更改了本文件中“范圍”的內(nèi)容（見(jiàn)第1章，2002年版的第1章）；

b）增加了術(shù)語(yǔ)和定義章節(jié)（見(jiàn)第3章）；

c）更改了“試驗(yàn)原理”并獨(dú)立成章（見(jiàn)第4章，2002年版的2.1）；

d）更改了“裝置”并獨(dú)立成章，更改標(biāo)題為“儀器設(shè)備”，增加了對(duì)計(jì)量器具的要求（見(jiàn)第5章，

2002年版的2.2）；

e）增加了裝置附圖中的尺寸標(biāo)注“L=25.0mm±0.2mm”（見(jiàn)圖1，2002年版的圖1）；

f）更改了試樣并單獨(dú)成章，更改標(biāo)題為“樣品”，并更改了樣品的要求（見(jiàn)第6章，2002年版

的2.3）；

g）增加了樣品不準(zhǔn)許試驗(yàn)的情況（見(jiàn)6.4）；

h）更改了“試驗(yàn)步驟”并單獨(dú)成章，修改了步驟的內(nèi)容（見(jiàn)第7章，2002年版的2.4）；

i）更改了“-100目球形粉末”代替“球形粉末”（見(jiàn)7.3，2002年版的2.4.3）；

j）更改了“試驗(yàn)結(jié)果”并單獨(dú)成章，并增加了數(shù)值修約（見(jiàn)第8章，2002年版的2.5）；

k）更改了橫向斷裂強(qiáng)度計(jì)算公式中“樣品寬度”和“樣品厚度”的單位（見(jiàn)8.1，2002年版的2.5）；

l）增加了“不確定度”章節(jié)（見(jiàn)第9章）；

m）增加了試驗(yàn)報(bào)告的內(nèi)容（見(jiàn)第10章，2022年版的第3章）。
