IEC 62840-2:2016 provides the safety requirements for a battery swap system, for the purposes of swapping swappable battery system (SBS) of electric vehicles. The battery swap system is intended to be connected to the supply network. The power supply is up to 1 000 V AC or up to 1 500 V d.c, in accordance with IEC 60038. This standard also applies to battery swap systems supplied from on-site storage systems (e.g. buffer batteries).
This publication is to be read in conjunction with IEC 62840-1:2016.

Technical committeeTypeAcronymIEC 62817:2014+AMD1:2017 CSVCommitteePublished year2017KeywordsDescription
IEC 62817:2014+A1:2017 is a design qualification standard applicable to solar trackers for photovoltaic systems, but may be used for trackers in other solar applications. The standard defines test procedures for both key components and for the complete tracker system. In some cases, test procedures describe methods to measure and/or calculate parameters to be reported in the defined tracker specification sheet. In other cases, the test procedure results in a pass/fail criterion. This standard ensures the user of the said tracker that parameters reported in the specification sheet were measured by consistent and accepted industry procedures. The tests with pass/fail criteria are engineered with the purpose of separating tracker designs that are likely to have early failures from those designs that are sound and suitable for use as specified by the manufacturer. This consolidated version consists of the first edition (2014) and its amendment 1 (2017). Therefore, no need to order amendment in addition to this publication.

Technical committeeTypeAcronymIEC 62808CommitteePublished year2015Description
IEC 62808:2015+A1:2018 establishes requirements for the design, analysis and qualification of isolation devices used to ensure electrical independence of redundant safety system circuits, or between safety and lower class circuits, as specified in IEC 60709. This standard includes guidance on the determination of the maximum credible fault that is applied to the isolation devices. The maximum credible fault can be used as a basis for the test levels used in testing based on other standards (e.g. IEC TS 61000-6-5 or IEC 62003). This consolidated version consists of the first edition (2015) and its amendment 1 (2018). Therefore, no need to order amendment in addition to this publication.

IEC 62805-2:2017 specifies methods for measuring the transmittance and reflectance of glass used in photovoltaic (PV) modules and provides instructions on how to calculate the effective hemispherical transmittance and reflectance of this glass. This document is applicable to PV glasses used in PV modules, including ultra-clear patterned glass, anti-reflective coated (AR) glass, transparent conductive oxide coated (TCO) glass and other kinds of PV glass used in PV modules. These test methods are designed to provide reproducible data appropriate for comparison of results among laboratories or at different times by the same laboratory and for comparison of data obtained on different PV glasses.

IEC 62790:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62790:2020 describes safety requirements, constructional requirements and tests for junction boxes up to 1 500 V DC for use on photovoltaic modules in accordance with class II of IEC 61140:2016. This document applies also to enclosures mounted on PV-modules containing electronic circuits for converting, controlling, monitoring or similar operations. Additional requirements concerning the relevant operations are applied under consideration of the environmental conditions of the PV-modules. This document does not apply to the electronic circuits of these devices, for which other IEC standards apply. This second edition cancels and replaces the first edition published in 2014. This edition includes the following significant technical changes with respect to the previous edition: - Modifications in normative references and terms and definitions; - Improvement of declaration of categories for junction boxes in 4.1; - Clarification for ambient temperature in 4.1; - Addition of requirement to provide information concerning RTE/RTI or TI in 4.2; - Reference to IEC 62930 instead of EN 50618 in 4.6; - Addition of "Functional insulation" in Table 1; - Addition of "Distance through cemented joints" in Table 3; - Correction of procedure of process to categorize material groups (deletion of PTI) in 4.15.2.3; - Requirement for approval of RTE/RTI or TI for insulation parts in 4.16.1 and 4.16.2; - Change of requirements concerning electrochemical potential in 4.17.2; - Clarification for IP-test in 5.3.4.2; - Addition of test voltage for cemented joints in 5.3.6 and 5.3.16; - Addition of detailled description on how to prepare the test sample for the thermal cycle test in 5.3.9.1; - New test procedure for bypass diode thermal test (5.3.18) in accordance with MQT 18.1 of IEC 61215-2:2016; - New test procedure for reverse overload current test in 5.3.23; - New Figure 1 for thermal cycle test.

IEC 62788-6-2:2020 provides methods for measuring the steady-state water vapour transmission rate (WVTR), water vapour permeability (P), diffusivity (D), solubility (S), and moisture breakthrough time (Ƭ10) (defined as the time to reach 10 % of the steady state WVTR) for polymeric materials such as encapsulants, edge seals, frontsheets and backsheets. These measurements can be made at selected temperatures and humidity levels as deemed appropriate for evaluation of their performance in PV modules. Measurement is accomplished by inspection of the transient WVTR curve and by fitting it to a theoretical Fickian model. This document is best applied to monolithic films. If multilayer films are used, the D and S values are only apparent values, but the steady-state values can still be measured.
