IEC 61000-4-18: 2019 focuses on the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, with regard to: a) repetitive slow damped oscillatory waves occurring mainly in power, control and signal cables installed in high voltage and medium voltage (HV/MV) substations; b) repetitive fast damped oscillatory waves occurring mainly in power,…

This document — defines smoking parameters and specifies the standard conditions to be provided for the routine analytical machine smoking of water pipe tobacco, where the water pipe tobacco sample is electrically heated only and not combusted; — specifies the requirements for a routine analytical smoking machine complying with the standard conditions. This document is only…

This document specifies three test methods for determining the bending stiffness of paper and paperboard. The test methods differ in the type of loading mode, thus giving rise to the two-point, three-point and four-point bending test methods. For paper and paperboard in a low thickness range, the two-point bending method and the three-point bending method are suitable. For corrugated fibreboard…
