37、ntrolled Copy, (c) BSI EN 60094-3:1996 BSI 09-19993 Section 1. Introduction 1 Scope This standard applies to recording and reproducing equipment for sound on magnetic tape (reel-to-reel, cassette and cartridge) for both professional and domestic applications, and will be referred to as “equipment” t
38、hroughout this standard. This standard does not apply to special purpose equipment such as high speed duplicators, artificial reverberation recorders or dictation machines not employing the reel-to-reel, cassette or cartridge principle. This standard excludes all aspects of safety, which are to be f
39、ound in IEC Publication 65, Safety Requirements for Mains Operated Electronic and Related Apparatus for Household and Similar General Use. It also excludes magnetic tape properties, which are to be found in IEC Publications 94-4 and 94-5. 2 Object The object of this standard is to list and define pa
40、rameters affecting the performance of recording and reproducing equipment for sound on magnetic tape, and to establish conditions and agreed methods of measurement of these parameters. Section 2. General notes on measurements 3 Information to be supplied by manufacturer of equipment The information
41、required is listed in this section. It falls into two distinct categories: mandatory information to be clearly shown on the equipment, indicated by an “A” on the right-hand side of the page; optional information to be given separately, e.g. in an instruction manual relating to and supplied with the
42、equipment. It is essential that mandatory information outside the scope of this standard (e.g. aspects of safety IEC Publication 65) shall also be given in the correct location. 4 Identification 5 Technical description All parameters in this clause are subject to verification only. For the purpose o
43、f this clause, an “adjustable” control shall be deemed to be one that is readily accessible to the user when the equipment is in its intended use. Its adjustment shall necessitate neither relocation of the equipment nor the dismantling of any of its parts. 6 Mechanical characteristics 6.1 Space and
