A variety of different kinds of IEC 60320 plugs and sockets. IEC 60320 Appliance couplers for household and similar general purposes [1] is a set of standards from the International Electrotechnical Commission (IEC) specifying non-locking connectors for connecting power supply cords to electrical appliances of voltage not exceeding 250 V (a.c.) and rated current not exceeding 16 A. [1 ...
The 12th edition of C18 began to be harmonized with the IEC standard. Rechargeable batteries were introduced in the C18 standard in 1984, and lithium types were standardized in 1991. In 1999 the ANSI standards were extensively revised and separate safety standards provided.
C18 bonded silica stationary phase column, a type of reversed-phase chromatography column; IEC 60320 C18, a power connector; Colorectal cancer (ICD-10 code) ISO/IEC 9899:2018 standard for the programming language C, informally named C18
C17, formally ISO/IEC 9899:2018, [1] is an open standard for the C programming language, prepared in 2017 and published in July 2018. It replaced C11 (standard ISO/IEC 9899:2011), [ 2 ] and is superseded by C23 (ISO/IEC 9899:2024) since October 2024. [ 3 ]
The IEC 60086 system calls the size R6, and ANSI C18 calls it 15. [1] It is named UM-3 by JIS of Japan. [2] Historically, it is known as D14 (hearing aid battery), [3] U12 – later U7 (standard cell), or HP7 (for zinc chloride 'high power' version) in official documentation in the United Kingdom, or a pen cell.

One or more AAA batteries are commonly used in low-drain portable electronic devices. A zinc–carbon battery in this size is designated by IEC as R03, by ANSI C18.1 as 24, by old JIS standard as UM-4, and by other manufacturer and national standard
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)
Like the D battery, the C battery size has been standardized since the 1920s. [5] The AA, AAA, and N sizes have been in common use since the 1950s. [6]The C battery is called "14" in current ANSI standards of battery nomenclature, and in IEC standards is designated "R14".
