The work of preparing International Standards is normally carried out through Iso technical committees. Each member body interested in a subject for which represented on that committee. International organizations, governmental and non-governmental, in liaison with IsO, also take part in the work. IsO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. circulated to the member bodies for voting.

Introduction Validation tests on vehicies have been conducted on the basis of IsO 11519-3:1994. The speed of data transmission has been increased up to 250 kTS/s with the same reliability providing that: Filter description and system characteristics are more precisely given, and parameter specifications of the transceiver are improved. Amendment 1 to ISO 11519-3 details the necessary changes to the 1994 Standard. Page 79 Add a hew clause before clause 8, to read as follows. 7.6 Alternative up to 250 kTS/s This clause describes the network interface up to 250 kTS/s. The definition of TS (Time Slot) is according to clause 7.2.3 Bit encoding of ISO 11519-3 (VAN). 7.6.1 System description 7.6.1.1 Functional block diagram This block diagram is given in figure 52 1 Copyright International Organization for Standardization ense from IHS Not for Resale 48519030609801157 SO11519-3:1994/Amd.1:1995(E) @ISO TRANSCEIVER Driver Idom Data DE DataB Irec Idom Receiver R14 Ri RO FILTER RiB R24 Polarization Pol Figure 52—250 kTS/s VAN bus interface Copyright International Organization for Standardization I without license from IHS Not for Resale 093 4851903 0609802 @ISO ISO 11519-3:1994/Amd.1:1995(E) 7.6.1.2 Filter section The:diagram is given in figure 53, together with the parameters.
