IEC 61331-3:20 14适用于防护设备，如防护服和护目镜，用于在放射检查和介入手术期间保护人员免受高达150 kV的X辐射。本标准涉及随附文件、设计和所用材料的一般要求，以及尺寸、特殊设计特征、材料的最小衰减特性、标记和符合本标准声明的标准化形式。它涵盖了主要用于保护操作员的防护服，例如: -防护围裙； -甲状腺项圈； -防护手套； -防护手套；和 -防护眼镜。它还包括用于保护患者的保护装置，例如: -保护性性腺围裙； -阴囊护罩；-卵巢屏蔽； -阴影护盾；和 -牙科用防护围裙。后一组保护装置旨在在放射检查期间使用，以最小化辐射对生殖器官的影响，特别是在遗传损伤方面。第二版取消并取代了1998年出版的IEC 61331-3的第一版。它构成技术修订。该第二版已经被适配以应用于本技术。它包括使用更好的方法来确定适用于设备使用的更广泛和更临床相关的辐射质量范围内的衰减特性的要求。它还包括三种额外的保护装置，甲状腺项圈、防护眼镜和牙科用防护围裙。

IEC 61331-3:2014 applies to protective devices such as protective clothing and eyewear for the protection of persons against X radiation up to 150 kV, during radiological examinations and interventional procedures. This standard deals with general requirements on the accompanying documents, on design and on materials used and with sizing, particular design features, minimum attenuation properties of materials, marking and standardized forms of statements of compliance with this standard. It covers protective clothing mainly for the protection of the operator, such as:
- protective aprons;
- thyroid collars;
- protective gloves;
- protective mittens; and
- protective eyewear. It also covers protective devices for the protection of the patient, such as:
- protective gonad aprons;
- scrotum shields;
- ovary shields;
- shadow shields; and
- protective aprons for dental use. The latter group of protective devices is intended to be used during radiological examinations to minimize the effects of irradiation on the reproductive organs particularly with regard to genetic damage. This second edition cancels and replaces the first edition of IEC 61331-3, published in 1998. It constitutes a technical revision. This second edition has been adapted to apply to the present technology. It includes a requirement to use a better method for the determination of attenuation properties over a broader and more clinically relevant range of radiation qualities appropriate to the use of the devices. It also covers three additional protective devices, thyroid collars, protective eyewear and protective aprons for dental use.
