[en] This part of ISO 17874 concerns multi-purpose remote handling tongs for nuclear applications. These remote handling tongs replace some functions of human hands and arms in inaccessible areas (generally, behind shielding or containment walls). In general, remote handling tongs provide limited functionality compared to master-slave manipulators, such as those described in ISO 17874-2. Remote handling tongs are typically used in hot cells for the following applications: fuel element examination, radio-isotope manipulation, reprocessing and waste treatment, radio-chemical analysis. Vertically mounted remote handling tongs are typically applied in pools for work on radioactive sources and irradiated fuel elements. End-effectors other than tongs, e.g. special-purpose tools, can be mounted on similar actuators, but these are not included within the normative part of this part of ISO 17874. This part of ISO 17874 addresses only manually-actuated remote handling tongs and does not address any powered versions. The purpose of this part of ISO 17874 is to provide guidance for the selection, installation and use of manually-operated remote handling tongs within nuclear installations. This part of ISO 17874 covers only the specific engineering aspects of manually-operated remote handling tongs and their interfaces with the nuclear facilities in which these devices are to be installed. Specifically, it does not address design options concerning aspects such as the process and general maintenance arrangements that lead to the selection of any particular type of remote handling device. The paper provides information on scope, normative references, terms and definitions, general features and classification, basic selection criteria, examples of special handling tongs, remote handling tongs for repetitive movements, articulated remote handling tongs used for delicate work and accessories. Six annexes report on sphere units, tongs jaws, accessories, gaiters for remote handling tongs, replacement of gaiters for remote handling tongs and relationship between the characteristics of the remote handling tongs and the operating volume
