There are two categories of APDUs: command APDUs and response APDUs. A command APDU is sent by the reader to the card – it contains a mandatory 4-byte header (CLA, INS, P1, P2) [2] and from 0 to 65 535 bytes of data.
IEC 60051 Direct acting indicating analogue electrical measuring instruments and their accessories; IEC 60052 Voltage measurement by means of standard air gaps; IEC 60055 Paper-insulated metal-sheathed cables for rated voltages up to 18/30 kV (with copper or aluminium conductors and excluding gas-pressure and oil-filled cables)
It specifies "a numbering system for the identification of the card issuers, the format of the issuer identification number (IIN) and the primary account number (PAN)", [1] and procedures for registering IINs. [2] It was first published in 1989. ISO/IEC 7812 has two parts: Part 1: Numbering system; Part 2: Application and registration procedures
By 1914, the IEC had issued a first list of terms and definitions covering electrical machinery and apparatus, a list of international letter symbols for quantities and signs for names of units, a list of definitions in connection with hydraulic turbines, and a number of definitions and recommendations relating to rotating machines and ...

The vector group provides a simple way of indicating how the connections of a transformer are arranged. In the system adopted by the IEC, the vector group is indicated by a code consisting of two or three letters, followed by one or two numeric digits. The letters indicate the winding configuration as follows:
