IEC TR 63282:2024, which is a technical report, collects information and report experience for the standardization of voltage levels and related aspects (power quality, EMC, measurement, etc.) for LVDC systems (systems with nominal voltage up to and including 1 500 V DC). Rationale for the proposed voltage values is given. Variation of parameters for the voltage (power quality) for their…

IEC 63338:2024 applies to the reuse and repurposing of secondary lithium ion and nickel-metal hydride cells and batteries after extraction from the application for which they were first placed on the market (hereafter "relevant cells and batteries"). This document does not permit reuse or repurposing of single cells or cell assemblies if battery lifetime traceability data are not…

This document provides a description of the primary services that have been internationally defined to promote consistency among implementations. Implementations can provide any of these services in combination with any other services that are appropriate. This document organizes ITS services by defining service groups, which are placed into one of several service domains. Each service group…

Scope 1.1 These requirements cover alarm valves for use in automatic wet-pipe sprinkler systems for fire protection service. Alarm valves covered by these requirements are of either the variable- or constantpressure type and are of the swing-check pattern. Ordinarily, variable-pressure alarm valves are acceptable for constant-pressure service without alteration; however, in some designs, that…
