IEC TS 62607-6-33:2025, which is a Technical Specification, establishes a standardized method to determine the key control characteristic
• defect density (%, nm2)
of single layer graphene films by
• electron energy loss spectroscopy (EELS in transmission electron microscopy (TEM)).
This document outlines a method for quantitative measurement of defects in graphene at the nanoscale.
The method specified in this document is applicable to single layer graphene acquired via chemical vapour deposition (CVD), roll-to-roll production and exfoliated graphene flakes to estimate the defect density.
In order to obtain reliable data, it is essential that the procedure is consistent for each specified condition from the preparation of the TEM specimen to its observation. It is essential to maintain the spatial resolution below 1 nm by alignment of the beam. The dispersion value, which covers the entire energy loss near edge structure (ELNES) region of the carbon-K edge and maintains the highest energy resolution corresponds to 0,1 eV/ch. Defects in graphene are determined by measuring the spectral differences between sp2 hybridized and sp2/sp3 hybridized atoms, which are obtained by calculating the amplitude ratio of the π* and σ* orbital spectra.

IEC 62933-4-3:2025 applies to the effects of the environmental conditions on Battery Energy Storage Systems (BESS). This document addresses these effects and identifies causes, chain of events and final effects on the BESS. Based on those effects, preventative or mitigating measures are described. Typical environmental effects on the BESS include, but are not limited to, the effects of lightning, seismic activities, water, air, flora, fauna, and humans.

IEC TS 62282-7-1:2025 covers cell assemblies, test station setup, measuring instruments and measuring methods, performance test methods, and test reports for PEFC single cells.
This document is used for evaluating:
a) the performance and durability of membrane electrode assemblies (MEAs) for PEFCs in a single cell configuration;
b) materials or structures of PEFCs in a single cell configuration; or,
c) the influence of impurities in fuel and/or in air on the fuel cell performance and durability.

IEC TS 63126:2025 defines additional testing requirements for photovoltaic (PV) modules deployed under conditions leading to higher module temperature which are beyond the scope of IEC 61215-1 and IEC 61730‑1 and the relevant component standards, IEC 62788‑1‑7, IEC 62788‑2‑1, IEC 62790 and IEC 62852. The testing conditions specified in IEC 61215-2 and IEC 61730-2 (and the relevant component standards IEC 62788‑1‑7, IEC 62788‑2‑1, IEC 62790 and IEC 62852) assumed that these standards are applicable for module deployment where the 98th percentile temperature (T98), that is the temperature that a module would be expected to exceed for 175,2 h per year, is less than 70 °C. This document defines two temperature regimes, temperature Level 1 and temperature Level 2, which were designed considering deployment in environments with mounting configurations such that the T98 is less than or equal to 80 °C for temperature Level 1, and less than or equal to 90 °C for temperature Level 2. This document provides recommended additional testing conditions within the IEC 61215 series, IEC 61730 series, IEC 62788‑1‑7, IEC 62788‑2‑1, IEC 62790 and IEC 62852 for module operation in temperature Levels 1 and 2. Successfully passing a higher Level for a test, sequence of tests, or complete testing for a higher Level is an implied passing of the relevant lower‑Level testing. For example, passing 200 thermal cycles for Level 2 is considered passing Level 0 and Level 1 for 200 thermal cycles.
