IEC 60749-34-1:2025 describes a test method that is used to determine the capability of power semiconductor modules to withstand thermal and mechanical stress resulting from cycling the power dissipation of the internal semiconductors and the internal connectors. It is based on IEC 60749-34, but is developed specifically for power semiconductor module products, including insulated-gate bipolar transistor (IGBT), metal-oxide-semiconductor field-effect transistor (MOSFET), diode and thyristor. If there is a customer request for an individual use or an application specific guideline (for example ECPE Guideline AQG 324), details of the test method can be based on these requirements if they deviate from the content of this document. This test caused wear-out and is considered destructive.

This document establishes the specification of the Basic image interchange format (BIIF). This document provides a foundation for interoperability in the interchange of imagery and imagery-related data among applications. It also provides a detailed description of the overall structure of the format, as well as specification of the valid data and format for all fields defined with BIIF. Annex C contains a Model Profile of BIIF in tables to assist in profile development. The scope and field of application of this document includes the capability to perpetuate a proven interchange capability in support of commercial and government imagery, Programmer’s Imaging Kernel System (PIKS) data, and other imagery technology domains in that priority order. This document provides a data format container for image, symbol, and text, along with a mechanism for including image-related support data. This document: — provides a means whereby diverse applications can share imagery and associated information; — allows an application to exchange comprehensive information to users with diverse needs or capabilities, allowing each user to select only those data items that correspond to their needs and capabilities; — minimizes preprocessing and postprocessing of data; — minimizes formatting overhead, particularly for those applications exchanging only a small amount of data and for bandwidth-limited systems; — provides a mechanism (Transportable File Structure, TFS) to interchange PIKS image and image-related objects; — provides extensibility to accommodate future data, including objects.

This document specifies the apparatus, materials, specimen preparation, procedures, results and reports for testing the corrosion test of steel bars. This document includes an evaluation method.

NOTE Annex A provides test apparatus examples. Annex B illustrates test results.

This document specifies the system layer of the coding. It was developed principally to support the combination of the video and audio coding methods defined in Parts 2 and 3 of ISO/IEC 13818. The system layer supports six basic functions: 1) the synchronization of multiple compressed streams on decoding; 2) the interleaving of multiple compressed streams into a single stream; 3) the initialization of buffering for decoding start up; 4) continuous buffer management; 5) time identification; 6) multiplexing and signalling of various components in a system stream. A Rec. ITU-T H.222.0 | ISO/IEC 13818-1 multiplexed bit stream is either a transport stream or a program stream. Both streams are constructed from PES packets and packets containing other necessary information. Both stream types support multiplexing of video and audio compressed streams from one program with a common time base. The transport stream additionally supports the multiplexing of video and audio compressed streams from multiple programs with independent time bases. For almost error-free environments the program stream is generally more appropriate, supporting software processing of program information. The transport stream is more suitable for use in environments where errors are likely. A Rec. ITU-T H.222.0 | ISO/IEC 13818-1 multiplexed bit stream, whether a transport stream or a program stream, is constructed in two layers: the outermost layer is the system layer, and the innermost is the compression layer. The system layer provides the functions necessary for using one or more compressed data streams in a system. The video and audio parts of this Specification define the compression coding layer for audio and video data. Coding of other types of data is not defined by this Specification, but is supported by the system layer provided that the other types of data adhere to the constraints defined in 2.7.

IEC 62074-1: 2025 applies to fibre optic wavelength division multiplexing (WDM) devices. These have all of the following general features: - they are passive, in that they contain no optoelectronic or other transducing elements; however they can use temperature control only to stabilize the device characteristics; they exclude any optical switching functions; - they have three or more ports for either the entry or exit of optical power, or both, and share optical power among these ports in a predetermined fashion depending on the wavelength; - the ports are optical fibres, or optical fibre connectors. This document establishes uniform requirements for the following: - optical, mechanical and environmental properties. This third edition cancels and replaces the second edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) harmonization of terms and definitions with IEC TS 62627-09; b) simplified classification, documentation and standardization system in Clause 4, and moving interface style to Annex H.

IEC 60068‑2-88:2025 establishes test methods for the resistance of electronic and electromechanical components, unpopulated circuit boards and assemblies to liquid cleaning media and cleaning processes, which are agreed between user and supplier for applications, where cleaning is required. These tests are not applicable to components, unpopulated circuit boards and assemblies, which are not intended to be subjected to cleaning processes. Tests XD1 and XD2 primarily are intended for qualification testing of components and unpopulated circuit boards suitable for cleaning processes, but can be adopted as well to testing of material compatibility and specific cleaning media used in manufacturing processes of components and unpopulated circuit boards. Test XD3 is intended to determine the resistance of electronic assemblies suitable for cleaning processes to the various cleaning processes to which they are exposed during manufacturing, including the effects of assembly and soldering processes.

This document specifies computational methods for determining the acoustical source level of projectile sound and its one-third octave band spectrum, expressed as the sound exposure level for nominal mid-band frequencies from 12,5 Hz to 10 kHz. It also specifies a method on how to use this source level to calculate the sound exposure level at a receiver position.
Results obtained with this document can be used as a basis for assessment of projectile sound from shooting ranges. Additionally, the data can be used to determine sound emission or immission from different types of ammunition and weapons. The prediction methods are applicable to outdoor conditions and straight projectile trajectories. Two computational methods are given to determine the acoustical source level: one for streamlined projectile shapes and one for non-streamlined shapes, such as pellets.

This document describes a classification of non-metallic blast-cleaning abrasives for the preparation of steel substrates before application of paints and related products.
It specifies the characteristics which are required for the complete designation of such abrasives.
This document applies to abrasives supplied in the new or unused condition only. It does not apply to abrasives either during or after use.
NOTE       Although this document has been developed specifically to meet requirements for preparation of steelwork, the properties specified will generally be appropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques. These techniques are described in ISO 8504-2.

This document applies to arc stud welding of metallic materials subject to static and fatigue loading.

For the working range of stud welding, see Annex B.

This document specifies a test method for determining the transverse flexibility (troughability) of a conveyor belt, expressed as a ratio, F/L. The method is not suitable or valid for light conveyor belts as described in ISO 21183-1.
NOTE            The transverse “flexibility” determined by the method described in this document is only indirectly associated with the inverse of flexural modulus as specified in ISO 178. Nor does it take into consideration the differences in “flexibility” as exhibited by three-point and four-point bending, which takes account of the flexural strain and the thickness of the test piece.
