前言

本标准等同采用IEC60522:1999((X射线管组件固有滤过的测定》。

本标准对IEC60522:1999作了下列编辑性修改:

删除了国际标准前言

本标准与前一版相比主要变化如下:

—本标准名称中增加了英文名称和增加了目次、前言和术语;

—对测量固有滤过时管电压的波形提出了要求，选用电压值有了变化;

—固有滤过测量值的达标范围改变;

—增加对基准材料的成分要求。

—增加多种材料组成的合成品的固有滤过的测定。

本标准的附录A为规范性附录

本标准由国家食品药品监督管理局提出。

本标准由全国医用X线设备及用具标准化分技术委员会归口。

本标准起草单位:上海医疗器械九厂。

本标准主要起草人:杜月珍、汤美朗。

本标准所代替的历次版本发布情况为:YY0062-1991

X射线管组件固有滤过的测定

范围和目的

1.1范围

本标准适用于医用诊断和放射治疗x射线管组件

1.2目的

本标准对医用诊断和放射治疗x射线管组件的固有滤过的概念做出定义并描述测定方法，本标准还包

含对随机文件和x射线管组件上标识的符合性声明的要求。

本标准提供测定x射线管组件的固有滤过的方法，该方法的准确度足以为取得所要求的总溉过提供合

适的附加滤过。

注1:本标准不含对固有魂过或总浪过的任何特定值的要求。对诊断用的X射线管组件和X射线设备在GB9706.12-

1997给出相应要求

注2:在本标准中描述的测定方法适用于型式试验，不以用户使用为目的。
