IEC TS 62862-2-1:2021 defines the requirements and the test methods for the characterization of thermal energy storage (TES) systems. This document contains the information necessary for determining the performance and functional characteristics of active direct and indirect thermal energy storage systems based on sensible heat in solar thermal power plants using parabolic-trough collector, Fresnel collector or tower central receiver technology with liquid storage media.
This document includes characterization procedures for testing energy storage system charge and discharge, as well as reporting the results. Test performance requirements are given and the instrumentation necessary for them, as well as data acquisition and processing methods and methods for calculating the results and their uncertainties.Technology -

IEC TS 62862-1-2:2017(E) defines the procedures for the creation of annual solar radiation data sets (ASR) for solar thermal electricity (STE) plant simulation. This document defines procedures needed for the ASR construction as well as its components and parameters. The scope of application of this document refers to the needs associated with solar thermal power plant projects and mainly related to the simulation of an annual period with a solar radiation sum close to a normal annual value (from among an estimation of all possible annual values).

IEC TS 62861:2017(E) This Technical Specification provides guidelines for establishing confidence in product reliability using principal component testing for LED light sources and LED luminaires for general lighting. It includes methods and criteria using initial qualification tests and accelerated stress tests of the principal components. The performance of any principal component will influence the performance of the final product.
Techniques to validate full lifetime claims and lumen maintenance projection are outside the scope of this Technical Specification. The following principal components are included in the testing if they are used as an integral part for the LED light source or LED luminaire:
- LED package and interconnects;
- optical materials;
- electronic subassemblies;
- cooling systems, both active (e.g. fans) and passive (e.g. thermal interface material);
- construction materials.
This Technical Specification is not recommended for use as a normative reference to the LED product performance standards.Technology -

IEC TS 62804-1:2015(E) defines procedures to test and evaluate the durability of crystalline silicon photovoltaic (PV) modules to the effects of short-term high-voltage stress including potential-induced degradation (PID). Two test methods are defined that do not inherently produce equivalent results. They are given as screening tests; neither test includes all the factors existing in the natural environment that can affect the PID rate. The methods describe how to achieve a constant stress level. The testing in this Technical Specification is designed for crystalline silicon PV modules with one or two glass surfaces, silicon cells having passivating dielectric layers, for degradation mechanisms involving mobile ions influencing the electric field over the silicon semiconductor, or electronically interacting with the silicon semiconductor itself.

IEC 62804-1-1:2020 defines procedures to test and evaluate for potential-induced degradation-delamination (PID-d) mode in the laminate of crystalline silicon PV modules-principally those with one or two glass faces. This document evaluates delamination attributable to current transfer between ground and the module cell circuit. Elements driving the delamination that this test is designed to actuate include reduced adhesion associated with damp heat exposure, sodium accumulation at interfaces, and cathodic gas evolution in the cell circuit, metallization, and other components within the PV module activated by the voltage potential. The change in power of crystalline silicon PV modules associated with the stress factors applied (the purview of IEC TS 62804-1) is not considered in the scope.

IEC TS 62789:2014 provides guidelines for the parameters to be specified for concentrator photovoltaic cells (both multijunction and single junction) and provides recommendations and references for measurement techniques. No attempt is made to determine pass/fail criteria for cells. The purpose is to define the performance and physical characteristics of concentrator cells. This specification may also be used for describing cell assemblies and receivers.

IEC TS 62788-7-2:2017(E) defines test procedures to characterize the weatherability of polymeric component materials used in photovoltaic (PV) modules or systems. The methods in this document have been focused on polymeric backsheets and encapsulants, but may be applied to other materials; however, these were not verified as part of the preparation. Exposures in this document are intended for reference by other standards and as a tool to support research and product development for PV components and modules. Different exposures may be used to target specific climate/mounting configurations, with the specifics of how to apply the exposures left to those standards (e.g. component characterization standards, module qualification standards).

IEC TS 62788-5-2:2020 provides guidelines to assess the ability of an edge seal to prevent moisture ingress from the edges of PV modules. This document does not cover frame adhesives (sometimes colloquially referred to as edge seals) which by design do not serve to prevent moisture ingress to a meaningful degree. Edge seals should keep moisture out, remain adhered, and maintain electrically insulation from the environment. Much of the testing can be done on the material level, but given the fact that there are multiple surfaces, materials interactions, and mechanical stresses, testing on mini modules or modules is necessary. To accomplish this, this document contains three types of test sample types, materials, mini-modules, and full-size modules. It is intended that a quick evaluation and comparison can be made using materials only. This would be followed up by more rigorous tests using mini-modules where all the interfaces are correctly represented. And finally, full-size module tests are used to evaluate the actual construction process to allow unanticipated concerns to be addressed.
