GB/T36917.2—2024

前言

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

定起草。

本文件是GB/T36917的第2部分。GB/T36917已經(jīng)發(fā)布了以下部分：

—第1部分：技工室用鋼質(zhì)刃具；

—第2部分：技工室用硬質(zhì)合金刃具；

—第3部分：銑床用硬質(zhì)合金刃具；

—第4部分：技工室用微型硬質(zhì)合金刃具。

本文件代替GB/T36917.2—2018《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》，與GB/T36917.2—2018相比，除結(jié)構(gòu)性調(diào)整和編輯性改動外，主要技術(shù)變化如下：

a）更改了范圍（見第1章，2018年版的第1章）；

b）增加了“術(shù)語和定義”一章（見第3章）；

c）更改了分類，增加了第三類適宜材料（見第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6.1.2，2018年版的

5.1.2）；

e）增加了桿長度的規(guī)定（見6.3.2）；

f）增加了“抽樣”一章（見第7章）；

g）增加了標號相關(guān)規(guī)定（見9.1），更改了標示規(guī)定，增加了顏色標注相關(guān)規(guī)定（見9.2，2018年版

的第8章）；

h）更改了器械標識中顏色標識的相關(guān)規(guī)定（見第10章，2018年版的第9章）；

i）更改了包裝標簽的相關(guān)規(guī)定，增加了用于包裝標簽的圖形符號規(guī)定（見第11章，2018年版的

第10章）；

j）增加了刃具切削刃標示和切削刃數(shù)目（見附錄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)我國的技術(shù)條件，提高可操作性（見

第3章）；

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

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)我國的技術(shù)條件，提高可操作性（見8.1、

8.2、8.4）；

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

9.1）；

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

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6.4）；

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

或商標和地址”，以提高可操作性（見第11章）。

Ⅲ

GB/T36917.2—2024

本文件做了下列編輯性改動：

—增加了本文件適用界限的陳述，刪除了范圍項下的注；

—刪除了ISO7787?2：2020第3章中對ISO和IEC術(shù)語數(shù)據(jù)庫的介紹內(nèi)容；

—將6.3的標題由“尺寸和切削刃數(shù)目”更改為“尺寸”；

—將8.2的標題由“尺寸和切削刃數(shù)目”更改為“尺寸”，將8.2中“通過目測確定切削刃數(shù)目”

移至8.3。
