high-voltage cables and cable systems with extruded insulation and mainly to be used on three-phase alternating systems operating at voltages exceeding U = 1 kV (in this standard the term ‘high voltage’ is used to cover any cable above 1 kV)

The purpose of this part of IEC 61300 is to provide a standard for the measurement of guide pin bore diameters in thermoplastic and thermoset MT ferrules specified in IEC 61754‑5

Ships and marine technology. Marine NOx reduction agent AUS 40 - Quality requirements Ingestion-build-53008 2 Basic requirements for composition1 Scope This part of ISO 18611 specifies the quality characteristics of the marine NOx reduction agent, aqueous urea solution at 40 % concentration (AUS 40), which is needed to operate so called SCR (selective catalytic reduction) converters. In marine applications, for example, for engine exhaust gas treatment, SCR converters are particularly suitable for selectively reducing the nitrogen oxide (NOx) emissions of internal combustion engines and
