This standard specifies the performance evaluation specifications of thermal transfer type printers (hereinafter referred to as bar code printers), consumables, and bar code readers (regardless of the reading method) used in bar code systems. The rank of performance is also defined by the evaluation items.

This standard can be applied to the following evaluation tests by combining ISO/IEC 15416 and ISO/IEC 15415, which define the print qualities of bar code symbols.

Note This standard is not prevented from being cited in the evaluation of thermal printers using thermal paper and printers using "plain or exclusive paper" (commercial printing, ink jet printers, electrophotographic printers, etc.).

a) Print performance of bar code printers (including consumables)

b) Brightness and smoothness of "reception paper or label", and adhesion of the label

c) Strength of reception paper or label on which the bar code is printed

d) Reading performance of bar code readers

e) Electrical, mechanical and environmental characteristics of bar code printers and bar code readers

This International Standard defines the requirements for the symbology known as rMQR. It specifies the rMQR symbology characteristics, data character encoding methods, symbol formats, dimensional characteristics, error correction rules, reference decoding algorithm, printing quality requirements and user-selectable application parameters.

The document specifies the syntax, semantics and decoding processes for MPEG Immersive Video (MIV). It provides support for playback of a three-dimensional (3D) scene within a limited range of viewing positions and orientations, with 6 Degrees of Freedom (6DoF). This document specifies the MIV extension of ISO/IEC DIS 23090-5(2E)1.

This document specifies a unified speech and audio codec which is capable of coding signals having an arbitrary mix of speech and audio content. The codec has a performance comparable to, or better than, the best known coding technology that might be tailored specifically to coding of either speech or general audio content. The codec supports single and multi-channel coding at high bitrates and provides perceptually transparent quality. At the same time, it enables very efficient coding at very low bitrates while retaining the full audio bandwidth.
This document incorporates several perceptually-based compression techniques developed in previous MPEG standards: perceptually shaped quantization noise, parametric coding of the upper spectrum region and parametric coding of the stereo sound stage. However, it combines these well-known perceptual techniques with a source coding technique: a model of sound production, specifically that of human speech.
