IEC TR 63357:2022(E) describes standardization roadmap of fault test methods for integrated circuits used in automotive vehicles. Since automotive vehicles are exposed in harsh environment such as very low or high temperature, vibration, high frequency signals, etc. Therefore, they are tested for possible faults which can be caused by harsh environment. There are several fault test methods and…

IEC TS 62607-6-20:2022 (EN) IEC TS 62607 establishes a standardized method to determine the chemical key control characteristic - metallic impurity content for powders of graphene-based materials by - inductively coupled plasma mass spectrometry (ICP-MS). The metallic impurity content is derived by the signal intensity of measured elements through MS spectrum of ICP-MS. - The method is…

IEC 62947-1:2022 specifies test methods to measure the performance of electrically operated spray seats for household and similar use. This document applies to spray seats, including tank-type spray seats, instantaneous-type spray seats and combination-type spray seats. This document does not apply to the electrically operated spray seats that are intended for medical and/or assistive functions…
