Abstract: The GB/T 4706 series of standards is currently in the transition period of version change. GB/T 4706.1—2024 Annex R introduces several major technical changes, primarily including a shift in the software evaluation framework from “Type A, B, C classification” to “Table R.1 / R.2 measures”, along with practical challenges arising from new process documentation requirements. Based on testing and certification practice, this study systematically analyses the main differences of Annex R between the new and old versions of the standard, clarifies its correspondence with GB/T 14536.1 Annex H, and distinguishes between the boundaries of safety responsibilities and the collaborative implementation pathways for complete appliances and components. In response to the common industry challenge of applicability determination, practical solutions and implementation paths are proposed—covering risk-oriented design processes, documentation system improvement, and simplified assessment methods—supported by typical case studies. Aims to provide practical guidance for household electrical appliance enterprises in adapting to the new standard requirements and to facilitate a smooth transition for the industry.
