Fire test for concentrator PV modules

Scope

IEC TS 63392:2025 specifies a test method for evaluating the basic fire behaviour of modules used in concentrating systems with a maximum DC system voltage of 1 500 V or less. Since the concentrator module may be exposed to flames due to flying embers or fire may be caused by the module itself due to hot spots or arching (internal fire), the tests outlined in this document are conducted in these two modes.
Applicable fire testing may be required by local codes but are not covered in this document.
CPV system or CPV modules mounted in or on buildings, shall fulfil national building and construction codes, regulations, and requirements and are not covered by this Technical Specification. If national or local codes define fire test requirements, they should be followed. If such requirements are not available, the following international and national standards give information for tests, which could be used: ISO 5657, ENV 1187-1 to -4, ANSI/UL 790, EN 13501-1.
