To accomplish this goal, this International Standard has reviewed ISO\/IEC 9995<\/p>\n<p>and ISO 9241-4:1998 to identify those design features of these two base standards which are to be followed, which<\/p>\n<p>are exempted from this International Standard and which are permitted variations.<\/p>\n<p>This International Standard is intended primarily to apply to full size portable keyboards (e.g. A4). It may also apply<\/p>\n<p>to other keyboards outside this scope. ISO 9241-4 contains a proposed alternative method for conformance by a<\/p>\n<p>test based on user performance and subjective rating scales.<\/p>\n<p>This International Standard consists of two major categories of guidelines for portable computers:<\/p>\n<p>1.
