GB/T 43058-2023Ammonia corrosion testing of photovoltaic(PV)modules (English PDF)

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents"

Drafting.

This document is modified to adopt IEC 62716.2013 "Ammonia Corrosion Test for Photovoltaic Modules".

Compared with IEC 62716.2013, this document has made the following structural adjustments.

---Chapter 3 "Terms and Definitions" has been added, resulting in the extension of subsequent chapter numbers;

---Added 5.3 "Light Aging Test".

The technical differences between this document and IEC 62716.2013 and their reasons are as follows.

---Replaced IEC 61646.2008 with the normatively quoted GB/T 18911 to adapt to my country's technical conditions (see 5.3);

---Replaced ISO /IEC 17025 with normatively quoted GB/T 27025 to adapt to my country's technical conditions (see Chapter 12);

---Use the current IEC 61215-1-1.2021, IEC 61215-1-2.2021, IEC 61215-1-3.2021, IEC 61215-1-4.

2021 and IEC 61215-2.2021 replaces IEC 61215.2005 (see Chapter 4, 7.2, 7.3, 10.2, 10.3, 11.2 and

11.3);

---Replaced IEC 61730-2.2004 with the current IEC 61730-2.2016 (see Chapter 4, 7.2, 7.3, 10.2, 10.3, 11.2 and

11.3);

---In order to coordinate with normative reference documents, change "10.2 Maximum Power Determination" to "MQT02 Maximum Power Determination", "10.15

"Wet leakage current test" was changed to "MQT15 wet leakage current test", and "10.6 standard test conditions" was changed to "MQT06.1 standard test"

Conditions" (see Figure 2);

---In order to coordinate with the normative reference documents, the "MST13 grounding continuity test" is changed to "MST13 equipotential grounding continuity test"

"Sexual Experiment" (see Figure 2);

---For ease of use, the specific content of pretreatment technical requirements is listed (see Chapter 6).

The following editorial changes have been made to this document.

---In order to coordinate with the existing standards, the name of the standard is changed to "Ammonia Corrosion Test of Photovoltaic Modules";

--- Figure 1 adds a footnote to preprocessing; Figure 2 deletes Note 4 of the international standard.
