IEC 61439-1 eliminated this loophole. Today, every assembly must be verified either by: For detailed information, the official IEC 61439-1 standard

The IEC 61439-1 standard, "Low-voltage switchgear and controlgear assemblies – Part 1: General rules," establishes the foundational safety and performance requirements for low-voltage electrical systems. It replaces the older IEC 60439 series, moving to a unified "design verification" approach involving testing, comparison, or assessment, rather than the previous TTA/PTTA classification.
