IEC 62841-3-12:2017+A1:2021 applies to transportable threading machines. The rated voltage is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools. The rated input is not more than 3 700 W. The limits for the applicability of this standard for battery tools are given in Annex K. This standard deals with the hazards presented by tools which are encountered…

IEC 60255-187-1:2021 specifies the minimum requirements for functional and performance evaluation of (longitudinal) differential protection designed for the detection of faults in ac motors, generators and transformers. This document also defines how to document and publish performance test results. This document defines the influencing factors that affect the accuracy under steady state…

IEC TR 62908-1-3:2021, which is a technical report, provides general information on pen touch technology with the aim toward standardization. This document includes an overview of the pen touch technology, critical performance characteristics, issues of characteristics measurements, and other information. The purpose of this documents is to provide an overview of the different products available…

This document defines —    the physical and chemical tests on raw reclaimed natural rubber, and —    the standard materials, standard test formulations, equipment, and processing methods for evaluating the vulcanization characteristics, and the mechanical properties of reclaimed natural rubber.

This document defines —    physical and chemical tests on raw reclaimed isobutene-isoprene (IIR) rubber, and —    standard materials, standard test formulations, equipment, and processing methods for evaluating the vulcanization characteristics and the mechanical properties of reclaimed isobutene-isoprene rubber.

This document specifies a general protocol for the observation of the meiofaunal community in the deep seabed. The standardized method can be used in any phase [baseline data acquisition, monitoring during and after mining (testing)] accompanying resource development, making it easier to compare data beyond differences in workers and waters. This document is intended for marine environment impact…

This document specifies a bioassay for the determination of the presence of unknown toxic contaminants in test seawater (see Figure A.1). It is based on the inhibition of photosynthetic activity of the marine cyanobacterium Cyanobium sp. (NIES-981) by such toxic contaminants. The inhibition is determined based on delayed fluorescence (DF) intensity. The method is rapid and requires less…

This document provides definitions of functional requirements for connectivity among nomadic devices, cloud servers and micro mobility during pre-trip, post-trip and while driving, which is defined in ISO/TR 22085-1, and datasets for providing seamless mobility service. In addition, it also delivers related standards required to develop and operate the service platform between a nomadic device…
