This document is identical to ISO/IEC 11319-1993, and the following four
30、 paragraphs are the original foreword as it appeared in that document.) IS0 (the International Organization for Standardization, and IEC (the Inter- national Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC partici
31、pate in the development of International Standards through tech- nical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees col- laborate in fields of mutual interest. Other international organizations, gov- ernm
32、ental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodi
33、es for voting. Publication as an International Standard requires approval by at least 75% of the national bodies casting a vote. International Standard ISO/IEC 11319 was prepared by the European Computer Manufacturers Association (as Standard ECMA-145) and was adopted, under a special “fast-track pr
34、ocedure”, by Joint Technical Committee ISO/IEC JTC 1, information technology, Sub-Committee 11, Nexible magnetic media for digital data interchange, in parallel with its approval by national bodies of IS0 and IEC.

41、4 h 5.2 Operating environment Cartridges used for data interchange shall be capable of operating under the following conditions temperature: 5 “C to 45 “C relative Humidity: 20 % to 80 % wet Bulb Temperature: 26 “C max. There shall be no deposit of moisture on or in the cartridge. Conditioning befor
42、e operating: If a cartridge has been exposed during storage and/or transportation to a condition outside the above values, before use the cartridge shall be conditioned in the operating environment for a time at least equal to the period during which it has been out of the operating environment, up
43、to a maximum of 24 h. NOTE 3 Rapid variations of temperature should lx avoided 5.3 Storage environment For long-term or archival storage of cartridges the following conditions shall be observed temperature: 5 “C to 32 “C relative Humidity: 20 % to 60 % wet Bulb Temperature: 26 “C max.
