IEC 62276:2025 applies to the manufacture of synthetic quartz, lithium niobate (LN), lithium tantalate (LT), lithium tetraborate (LBO), and lanthanum gallium silicate (LGS) single crystal wafers intended for use as substrates in the manufacture of surface acoustic wave (SAW) filters and resonators. This edition includes the following significant technical changes with respect to the previous…

L'IEC 62276:2025 s’applique à la fabrication de tranches monocristallines de quartz synthétique, de niobate de lithium (LN), de tantalate de lithium (LT), de tétraborate de lithium (LBO) et de silicate de gallium et de lanthane (LGS), destinées à être utilisées comme substrats dans la fabrication de résonateurs et de filtres à ondes acoustiques de surface (OAS). Cette édition inclut les…

The content of this document is divided into two parts. —     This document analyses the overall configuration of an industrial digital twin system, and proposes a three-elements architecture, focusing on the twinning interface between the physical twin (PTw) and industrial digital twin (iDTw). —     The characteristics, and the visualization elements and visualization fidelity of iDTw are…

This document specifies principles for the tandem technique and the longitudinal-longitudinal-transverse wave (LLT) technique for detection of discontinuities perpendicular to the surface or almost perpendicular to the surface. The general principles for ultrasonic testing of industrial products are described in ISO 16810. The tandem or LLT techniques can be used for the detection of embedded…

IEC 62541-15:2025 describes a safety communication layer (services and a protocol) for the exchange of SafetyData using IEC 62541 mechanisms. It identifies the principles for functional safety communications defined in IEC 61784‑3 that are relevant for this safety communication layer. This safety communication layer is intended for implementation in safety devices only. NOTE 1 This document…

This document specifies physical and performance requirements, test methods and marking requirements for industrial protective helmets. This document describes the requirements for two helmet types. Type I — intended to protect the upper part of wearer’s head against impacts that may occur in an industrial setting, such as a falling object. Type II — intended to protect the head against impacts…
