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. Annexes A, B and C form an integral part of this International Standard. Annexes D and

40、1 Testing environment Unless otherwise specified, tests and measurements made on the cartridge to check the requirements of this International Standard shall be carried out under the following conditions temperature: 23 “C ?r 2 OC relative Humidity: 40 % to 60 % conditioning period before testing: 2

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. The stray magn

44、etic field at any point on the tape shall not exceed 4 000 A/m. There shall be no deposit of moisture on or in the cartridge. 5.1 Transportation Recommended limits for the environment to which a cartridge may be subjected during transportation, and the precautions to be taken to minimize the possibi

45、lity of damage, are provided in annex D. 5.5 Safety The cartridge and its components shall satisfy the requirements of IEC 950. 5.6 Flammability The cartridge and its components shall be made from materials which, if ignited from a match flame, do not continue to burn in a still carbon dioxide atmos
