Information technology — Lossy/lossless coding of bi-level images
1 Scope
This Recommendation | International Standard1 defines methods for coding bi-level images and sets of images (documents consisting of multiple pages). It is particularly suitable for bi-level images consisting of text and dithered (halftone) data.
The methods defined permit lossless (bit-preserving) coding, lossy coding, and progressive coding. In progressive coding, the first image is…
High frequency inductive components - Non-electrical characteristics and measuring methods - Part 2:...
IEC 62025-2:2019 specifies a test method for the non-electrical characteristics of the surface mounted device (SMD) inductors to be used for electronic and telecommunication equipment. The object of this part of this document is to define methods for measuring mechanical performance only. As the reliability performances and specifications relative to non-electrical performances are defined in IEC…

Electricity metering data exchange - The DLMS/COSEM suite - Part 5-3: DLMS/COSEM application layer
IEC 620565-3:2013 specifies the DLMS/COSEM application layer in terms of structure, services and protocols for COSEM clients and servers, and defines how to use the DLMS/COSEM application layer in various communication profiles. It defines services for establishing and releasing application associations, and data communication services for accessing the methods and attributes of COSEM interface…
Information technology — Keyboard layouts for text and office systems — Part 3: Complementary layout...
1 Scope
Within the general scope described in ISO/IEC 9995-1, this part of ISO/IEC 9995 defines the allocation on a
keyboard of a set of graphic characters which, when used in combination with an existing national version
keyboard layout or the complementary Latin group layout as defined in this part of ISO/IEC 9995, allows the
input of a minimum character repertoire as defined by collection 281…

Information technology — Database languages — SQL — Part 4: Persistent Stored Modules (SQL/PSM)
ISO/IEC 9075 defines Structured Query Language (SQL). The scope of SQL is the definition of data structure and the operations on data stored in that structure. ISO/IEC 9075-1, ISO/IEC 9075-2 and ISO/IEC 9075-11 encompass the minimum requirements of the language. Other parts define extensions.
ISO/IEC 9075-4:2011 specifies the syntax and semantics of statements to add a procedural capability to…
