Scope
GB/T 9435-2012 is the English-translated version of 彩色显像管有效屏面尺寸.
GB/T 9435-2012 sets out how the useful screen dimensions of a colour picture tube are calculated.
It gives the calculation of the useful diameter and of the useful area for spherical and for non-spherical panels, 16:9 tubes included, and defines the terms the calculation rests on - the screen, the inside transition radius, the centre distance, the minimum useful size taken along the major, minor and diagonal axes, and the useful area bounded by the locus of the minimum useful radius of curvature - with worked examples in Appendix A. Clause 1 limits it to the calculation of the useful screen of colour picture tubes, and it quotes GB/T 8170 for rounding and limit values.
It replaces GB/T 9435-1988, was issued on 5 November 2012 and has applied since 15 February 2013.

Foreword
This standard rule according to GB/T 1.1-2009 given draft.
This standard replaces GB/T 9435-1988 "color CRT effective screen size." This standard and GB/T 9435-1988 compared to the main changes are as follows.
--- Increased in Chapter 2, normative references;
--- Modify the calculation method of the effective area of the spherical color picture tube;
--- Increased 4.3 aspherical color cathode ray tube diameter and effective calculation method of the effective area;
--- Increasing the effective diameter of the color picture tube 16.9 and calculation method of the effective area;
--- Adjustment and increases the calculation example in Appendix A.
The standard proposed by the Ministry of Industry and Information Technology of the People's Republic of China.
1 Scope

3 Terms and Definitions
The following terms and definitions apply to this document.
3.1 Screen
Along the tube axis parallel to the direction of the tube to see the panel section.
3.2 The inner surface of the transition radius
Transition radius of the inner surface of the inner side of the screen.
3.3 Center distance
In the same axis of symmetry, both the inner surface of the transition radius of the center of the pitch.
3.4 Effective diameter useful screen dimensions
3.4.1 The effective diameter of the spherical screen
Major and minor axis and diagonal "minimum effective size." Figure 1, the central axis of symmetry of the inner surface of the transition radius distance (IL, IS, ID)
Position to the inner surface of the transition radius R and the tube axis forming a 30 ° inner surface of the transition radius and center distance using the design value screen.
3.4.2 Aspherical effective screen diameter
Major axis, minor axis and diagonal axis "and the center value of the relative error." Shown in Figure 3, the inner curve Z = f (x, y) and the inner surface of the two fillets 2-fold by tangential point P to the tube axis distance inner surface Z = f (x, y) and the inner surface of the transition radius R of the screen using the design value.
3.5 Effective area useful area
3.5.1 Spherical screen effective area
Minimum effective radius of curvature of the trajectory of the area surrounded by the boundary.
