This part of IEC/IEEE 62582 specifies methods for condition monitoring of organic and polymeric materials in instrumentation and control systems using oxidation induction techniques in the detail necessary to produce accurate and reproducible measurements. It includes the requirements for sample preparation, the measurement system and conditions, and the reporting of the measurement results. The different parts of IEC/IEEE 62582 are measurement standards, primarily for use in the management of… read more ageing in initial qualification and after installation. IEC/IEEE 62582-1 includes requirements for the application of the other parts of the IEC/IEEE 62582 and some elements which are common to all methods. Information on the role of condition monitoring in the qualification of equipment important to safety is found in IEC/IEEE 60780-323. read less

This International Standard specifies computational procedures using Finite-Difference Time-Domain (FDTD) and Finite Element Methods (FEM) to assess the peak and spatial-averaged power density relevant to the human exposure of the human head or body from devices operating between 6 GHz and 300 GHz. It applies to devices with radiating structures at distances up to and including 200 mm. This includes but is not limited to mobile phones, tablets, and wearables. This standard provides a… read more conservative estimate of the power density of the exposure of the head or body for a significant majority of persons during normal use of these devices. read less
