CAN/CSA-ISO/IEC 9995-8-07

Preface

Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).

Scope


Within the general scope described in lSO/IEC 9995-1, this part of lSO/IEC 9995 specifies the allocation of letters to the keys of the numeric zone ZN0 of a keyboard which has the ten digits zero to nine allocated in the 1-2-3 layout. The layout specified in this part of lSO/IEC 9995 is intended for applications of information technology equipment keyboards where letters instead of digits are used for the mnemonic retention of numeric information.

The use of letters on the numeric zone ZN0 for the mnemonic retention of numeric information is strongly deprecated on keyboards which also contain an alphanumeric section. The inclusion of two sets of alphabetical symbols used in different ways could confuse the user of the keyboard.
