5、rt 1 : General Condi- tions and Requirements. The clause numbers in this part correspond to those in I EC Publication 94-1 and any text given in this part shall modify the text given in IEC Publication 94-1. Absence of text in this part indicates that the provisions of the relevant clause in I EC Pu
6、blication 94-1 apply. SECTION ONE - GENERAL 1. Scope This part applies only to cassette recording and reproducing systems. SECTION TWO - MECHANICAL REQUIREMENTS 12. Replacement: Mechanical requirements and dimensions of cassette recording systems any cassette recorder or player are given in Figures
7、1 to 12, pages 16 to 24. Constructional data which standardize the cassette to secure interchangeability of cassettes on D ThX-, Y- and Z-reference planes in the figures have been defined as follows: o The Z-reference plane is the plane established by three points which are positioned half of the di
8、stance between three reference areas U, V and W on one cassette side and three correspond- ing ones on the other side (see Figure 9, page 22). o The X-reference plane per cassette side is defined as the common tangential plane at the rear of both positioning holes per side, perpendicular to the Z-re
9、ference plane. o The Y-reference plane is defined perpendicular to the relevant X- and the Z-reference plane and is situated at the mid-point of the centres of the reference holes (see Section D-D in Figure 2, page 17). Note. - These definitions show that a cassette can fulfil the dimensional requir
10、ements in this standard only on the basis of two X-reference planes and two Y-reference planes. Furthermore, the following requirements shall apply: IEC page 91 STD-BSI BS EN bOO7nt donns dans leur mndition mathelle maximale et sont sy Lb2LibbS 058783b b05 Page 10 EN 600947 : 1993 37.4 I G.2 66.6 rt
