c）更改了分類，增加了第三類適宜材料（見(jiàn)第5章，2018年版的第3章）；

d）更改了桿材料的要求，增加了類型選擇及其處理方法由制造商決定（見(jiàn)6.1.2，2018年版的

5.1.2）；

e）增加了桿長(zhǎng)度的規(guī)定（見(jiàn)6.3.2）；

f）增加了“抽樣”一章（見(jiàn)第7章）；

g）增加了標(biāo)號(hào)相關(guān)規(guī)定（見(jiàn)9.1），更改了標(biāo)示規(guī)定，增加了顏色標(biāo)注相關(guān)規(guī)定（見(jiàn)9.2，2018年版

的第8章）；

h）更改了器械標(biāo)識(shí)中顏色標(biāo)識(shí)的相關(guān)規(guī)定（見(jiàn)第10章，2018年版的第9章）；

i）更改了包裝標(biāo)簽的相關(guān)規(guī)定，增加了用于包裝標(biāo)簽的圖形符號(hào)規(guī)定（見(jiàn)第11章，2018年版的

第10章）；

j）增加了刃具切削刃標(biāo)示和切削刃數(shù)目（見(jiàn)附錄A）；

k）更改了表12中切削刃數(shù)目，刪除了表12中關(guān)于左右及公稱直徑的表注（見(jiàn)表A.1，2018年版的

表12）。

本文件修改采用ISO7787?2：2020《牙科學(xué)技工室用刃具第2部分：技工室用硬質(zhì)合金刃具》。

本文件與ISO7787?2：2020的技術(shù)差異及其原因如下：

—用規(guī)范性引用的GB/T9937替換了ISO1942，以適應(yīng)我國(guó)的技術(shù)條件，提高可操作性（見(jiàn)

第3章）；

—用規(guī)范性引用的YY/T0967替換了ISO1797，以適應(yīng)我國(guó)的技術(shù)條件，提高可操作性（見(jiàn)

第5章、6.3.2、第11章）；

—用規(guī)范性引用的YY/T0874替換了ISO8325，以適應(yīng)我國(guó)的技術(shù)條件，提高可操作性（見(jiàn)8.1、

8.2、8.4）；

—用規(guī)范性引用的YY/T1011替換了ISO2157，以適應(yīng)我國(guó)的技術(shù)條件，提高可操作性（見(jiàn)

9.1）；

—用規(guī)范性引用的YY/T0466.1替換了ISO15223?1，以適應(yīng)我國(guó)的技術(shù)條件，提高可操作性（見(jiàn)

第11章）；

—增加了切削刃數(shù)目的要求，將“刃具切削刃的選擇由制造商規(guī)定”更改為“刃具切削刃的選擇

和數(shù)目由制造商規(guī)定”，以提高可操作性（見(jiàn)6.4）；

—將包裝標(biāo)簽a）中“制造商或其授權(quán)代理商的名稱和/或商標(biāo)和地址”更改為“制造商的名稱和/

或商標(biāo)和地址”，以提高可操作性（見(jiàn)第11章）。
