IS 16792 : Part 1 : Sec 4 : 2023/IEC 62788-1-4 : 2016+AMD1 : 2020 Measurement Procedures for Materials Used in Photovoltaic Modules - Part 1 Encapsulants - Section 4 Measurement of Optical Transmittance and Calculation of the Solar- Weighted Photon Transmittance, Yellowness Index, and UV Cut-Off Wavelength
Revised Standard from Last Update.
NATIONAL FOREWORD
This Indian Standard (Part 1/Sec 4) (First Revision) which is identical with IEC 62788-1-4 : 2016 + Amd 1 : 2020 ‘Measurement procedures for materials used in photovoltaic modules — Part 1-4: Encapsulants — Measurement of optical transmittance and calculation of the solar-weighted photon transmittance, yellowness index, and UV cut-off wavelength’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Solar Photovoltaic Energy Systems Sectional Committee and approval of the Electrotechnical Division Council.
This standard was first published in 2019. This first revision has been undertaken to take into consideration the developments that have taken place subsequently and also to align with the latest version of IEC 62788-1-4 : 2016 + Amd 1 : 2020.
