4、ents National foreword This British Standard is the official English language version of EN ISO 9241-6:1999. It is identical with ISO 9241-6:1999. It supersedes BS 7179-6:1990 which is withdrawn. The UK participation in its preparation was entrusted to Technical Committee PH/9, Ergonomics, to Subcom
5、mittee PH/9/6, User system interfaces, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international an
6、d European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to inter
7、national publications with their corresponding European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facil
