Annotation of standard text IEC 61331-2-ed.2.0 :
IEC 61331-2:2014 applies to translucent protective plates used for radiation protection in X-ray diagnosis and in X-ray therapy. It also applies to translucent protective plates used for protection against gamma radiation in nuclear medicine and brachytherapy with automatically-controlled afterloading equipment. It does not cover other translucent radiation protection materials, e.g. leaded glasses or goggles for protection of the operators eyes (eye spectacles); leaded face shields, which cover the entire face of the operator; patient eye protection; and thyroid/neck protective devices. This Part 2 deals with the requirements on: - geometrical accuracy; - optical quality of the material; - spectral transmittance; - radiation attenuation properties; - marking; and - statement of compliance with this standard. This second edition cancels and replaces the first edition of IEC 61331-2, published in 1994. It constitutes a technical revision. This second edition has been adapted to apply to the present technology. The essential changes and extensions are: - extension of scope to cover all kinds of translucent protective plates and all kinds of radiation qualities and gamma radiation; - removal of definition and requirements for translucent protective plates for visual imaging; - changes of requirements concerning geometrical accuracy and optical quality; - changes of requirements concerning determination of lead equivalent and minimal thickness; and - changes of requirements concerning information and marking. LIEC 61331-2:2014 sapplique aux plaques translucides de protection radiologique utilisees pour la radioprotection dans le cadre du diagnostic medical et de la radiotherapie par rayonnement X. Elle sapplique egalement aux plaques translucides de protection radiologique utilisees pour la protection contre le rayonnement gamma en medecine nucleaire et en curietherapie avec des appareils de projection de sources a controles automatiques. Elle ne couvre pas dautres materiaux translucides de radioprotection, par exemple: - les verres ou lunettes protectrices au plomb pour les yeux des operateurs (lunettes oculaires); - les ecrans au plomb couvrant tout le visage de loperateur; - les protections pour les yeux du patient; et - les dispositifs de protection radiologique pour la thyroide ou le cou. La presente Partie 2 traite des exigences relatives: - a la precision geometrique; - a la qualite optique du materiau; - au facteur de transmission spectrale; - aux proprietes dattenuation du rayonnement; - au marquage; et - a la declaration de conformite a la presente norme. Cette deuxieme edition annule et remplace la premiere edition de lIEC 61331-2, parue en 1994. Elle constitue une revision technique. Cette deuxieme edition a ete adaptee pour sappliquer a la technologie actuelle. Les principales modifications et extensions sont les suivantes: - extension du domaine dapplication pour couvrir tous les types de plaques translucides de protection radiologique et tous les types de qualites de rayonnement et de rayonnement gamma; - suppression de la definition et des exigences pour les plaques translucides de protection radiologique en imagerie visuelle; - modification des exigences concernant la precision geometrique et la qualite optique; - modification des exigences concernant la determination de Lequivalent plomb et de lepaisseur minimale; et - modification des exigences concernant les informations et le marquage.
