IEC 60893-2:2023 describes methods of test for the materials defined in IEC 60893-1 (referred to also as Part 1). This third edition cancels and replaces the second edition published in 2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) removal of reference to withdrawn specification IEC…
Information technology — JPEG 2000 image coding system — Part 2: Extensions
This document defines a set of lossless (bit-preserving) and lossy compression methods for coding continuous-tone, bi-level, grey-scale, colour digital still images, or multi-component images.
This document:
– specifies extended decoding processes for converting compressed image data to reconstructed image data;
– specifies an extended codestream syntax containing information for…
Earth-moving machinery and machinery for forestry — Operator protective structures — Material perfor...
This document specifies the material performance requirements for structural members and fasteners used in operator protective structures for self-propelled earth-moving machinery and self-propelled machinery for forestry. Earth-moving machinery is defined in ISO 6165 and machinery for forestry is defined in ISO 6814.
This document applies to part-turn actuated valve assemblies comprising valve (e.g. ball valve, butterfly valve, and plug valve), actuator and, when required, a mounting kit supplied as a package.
It defines the design considerations necessary for automating valves, the responsibilities for the information required and tasks to be completed, to ensure suitable actuator and mounting kit sizing,…
