1.1 This Guide establishes the principles and gives recommendations on the design and formulation of instructions for use of products of consumer interest. It is intended for
— product designers, manufacturers, technical writers or other people engaged in the work of conceiving and drafting such instructions;
— committees preparing standards for consumer products.
1.2 The principles and detailed recommendations in this Guide should apply in combination with the specific requirements on instructions for use laid down in standards for specific products or groups of products.
1.3 Assessment of the quality of instructions for use should follow common criteria. This Guide therefore has an informative annex (Annex A) containing some practical recommendations and a proposed methodology for assessment. The annex is addressed primarily to researchers and experts engaged in such assessment work; it may also be helpful to the Guide's principal target groups named in 1.1.
