1 Scope and object
This clause of Part 1 is applicable except as follows:
1.1.1 Equipment included in scope
Replacement:
Replace the text, except the first paragraph, with the following new text:
This part of IEC 61010 is applicable to electrically operated laboratory equipment and its
accessories for mechanical mixing and stirring, where mechanical energy influences the
shape or size or homogeneity of materials and their accessories. Such devices can contain
heating elements.
NOTE If all or part of the equipment falls within the scope of one or more other Part 2 standards of the IEC 61010
series as well as within the scope of this document, consideration is given to those other Part 2 standards. The
standard for equipment which contains heating devices is IEC 61010-2-010.
