The code block structure is described
13、below. The order of the codes used in the code block indicates the structure of the cable, from the centre outwards. For the sake of clarity, special characters such as hyphens, plus signs and parentheses may also be used. 3.2 Cable type code The code block always starts with one of the following ch
14、aracter groups, depending on the nominal voltage: FL (Fahrzeugleitung: vehicle cable) voltage class A as defined in ISO 6469-3 FHL (Fahrzeug-Hochvolt-Leitung: vehicle high-voltage cable) voltage class B as defined in ISO 6469-3 FZL (Fahrzeug-Zndleitung: vehicle ignition cable) as defined in ISO 3808
15、 3.3 Special design feature codes Where necessary, the code for special design features (see Table 1) is placed directly after the cable type code. If there are several special design features, these codes shall be arranged in alphabetical order. Table 1 Special cable design features Code Meaning F

No code is used for copper c
17、onductors. Other conductor materials shall be identified by the codes listed in Table 2. Table 2 Codes for conductor materials Code Meaning Al aluminium W resistor material M other conductor materials To identify other conductor materials more precisely, the alloy designation may be used instead of
18、the code M. To identify the alloys, the chemical abbreviations normally used in the periodic system of elements shall be used, without concentration information. 3.5 Insulation wall thickness Where necessary, the code for the insulation wall thickness (see Table 3) is placed after the codes for cabl

The shea
21、th material code is placed at the position corresponding to the location of the sheath in the cable structure, beginning from the centre outwards.
