10、e designation System (WTDS) for TV Picture Tubes and Monitor Tubes. EIA TEPLOb-B 88 m 3234600 0007403 2 m I WORLDWIDE TYPE DESIGNATION SYSTEM . FOR TV PICTURE TUBES AND MONITOR TUBES Type designations for TV picture tubes and monitor tubes shall consist of six symbols of alternating groups of letter
11、s ahd numbers. These symbols shall have the following significance: The first symbol defines the application category of the tube and shall consist of a single letter. For TV picture tubes, this will be the letter A. For monitor tubes (direct-view, raster-scan display tubes for applications other th
12、an consumer TV), this will be the letter M. The second symbol defines the minimum viewable screen diagonal and shall consist of a two-digit number. This number shall be determined by the glass panel design-centre value in centimetres of the minimum viewable screen diagonal. A tube having its screen
13、diagonal within plus or minus one-half centimetre shall be assigned that integer. A tube falling exactlyon a one-half centimetre shall be assigned the next larger integer. The third symbol (family code) defines the tube types having specific mechanical and electrical characteristics and shall consis
14、t of three letters, excluding the letters I and O. See Guidelinesfor Assigning a New Type Number (pages 7 and 12) for tube variations that require a new third symbol. The third symbol is assigned by the type administrator in alphabetical sequence from left to right (AAA, AAB, AAC, . . . AZZ, BAA,. .
15、 . BZZ, . . . ZZZ). Once a combination has been assigned to a sponsor for a particular tube type, that combination shall be reserved for future assignments to the original sponsor. In this way the same combination will be available to a sponsor so that the familyrelationship may be maintained for di
16、fferent sizes. The four categories of tubes covered by this system - colour TV picture tubes, colour monitor tubes, monochrome TV picture tubes, and monochrome monitor tubes - shall be assigned third symbols in one continuous alphabetical sequence. Where the characteristics are identical, the same f
17、amily code may be assigned for monitor and TV picture tubes at the option of the sponsor. The fourth symbol (member of family) defines specific tube types within thefamilyspecified bythe third symbol.1 The fourth symbol consists of a two-digit number from O0 to 99.2 The fourth symbol is assigned ind
18、ependent of the third symbol. See Guidelines for Assigning a New Type Number (pages 7 and 12) for tube variations that require a new fourth symbol. 0 The fifth symbol defines the phosphor category. For colour TV picture tubes, the phosphor is defined by the letter X or the letters XX. Forcolour moni
19、tor tubes, the phosphor (usually tricolour) may be defined by the letter(s) XI XX, orsome other two-letter combination3, excluding the letters I and O. For monochrome TV picture tubes, the phosphor is defined by the letters WW. For monochrome monitors, the phosphor may be defined by the letters WW o
20、r some other two-letter combination, excluding the letters I and O. Phosphor designations that begin with the letter M are custom phosphors. The second letter indicates the tube manufacturer. These phosphors are intended for short production runs and are controlled by the tube manufacturer. Definiti
21、ons of the phosphor assignments are contained in the latest issue of EIA Publication TEP-116. The sixth symbol is only assigned to tubes having integral neck components. It defines the characteristics of these components and their adjustments. The sixth symbol consists of a two-digit number from O1
22、to 99. 1 At the option of the sponsor, a new third symbol may be assigned for any tube variation. 2 Previously, the fourth symbol consisted of a one-digit number from O to 9 for monochrome tubes. Type designations assigned under the previous rule shall remain valid. 3 Single-letter colour phosphor a
23、ssignments were made prior to the adoption of the two-letter code. Although these single-letter assignments are valid, each one has been assigned a corresponding two-letter code as follows: A (DA), B (DB), C (DC), D (XB), E (DD), F (XC), G (DE), X (XX), and Y (XY). 0 f 1 EIA TEPLOb-B 8 m 3234b00 000
