scope:

The objectives of this International Standard are to ensure that the design and functioning of the dental operator's stools will be such as to enable the dental operator to perform his or her work effectively and safely, to minimize the muscular and skeletal stresses, particularly in shoulders and spine, that arise during the performance of the work, and to allow freedom of movement without undue muscular activity. This International Standard specifies requirements and includes methods of test to be performed on the dental operator's stool to cover ergonomic, hygienic and safety characteristics.
