Standard Test Method for Determination of Long-Term Thermal Resistance of Closed-Cell Thermal Insula...
Scope
1.1 This procedure defines the long-term thermal resistance (LTTR) of a foam product as the value
measured after 5-year storage in a laboratory environment and provides means for its prediction based on
an accelerated laboratory test.
1.2 This procedure, based on ASTM standard test methods ASTM C1303 and ASTM C518, can be
applied to a wide range of preformed as well as field…
Product category rules for life cycle assessment of electrical and electronic products and systems
IEC 63366:2025 defines product category rules (PCR) for electrical and electronic products and systems (EEPS) to develop Type III environmental declarations for electrical and electronic products and systems (EEPS). It specifies the process and requirements on how to conduct life cycle assessment (LCA) in the context of environmental declarations.
This document provides common rules for:
a) LCA…
Rotating electrical machines - Part 15: Impulse voltage withstand levels of form-wound stator coils ...
IEC 60034-15: 2025 relates to AC machines incorporating form-wound stator coils that are intended to be connected to a standard grid supply. It specifies the test procedures and voltages to be applied to sample coils, as well as routine tests performed on coils mounted in the stator core. The purpose of this document is to show the ability of a stator winding to resist voltage transients…
A meta-modelling analysis approach to smart manufacturing reference models
IEC TR 63319:2025 uses a meta-modelling approach to identify commonalities among ten smart manufacturing reference models. Each reference model is placed into the context of the meta-model to facilitate analysis of both common and distinct features. Major smart manufacturing reference model topics are identified, and the reference models compared within each topic.
As part of the meta-modelling…
