Why are different naming standards compatible for use in the international market?

Compatibility is driven by technical parameter alignment. While a cable might be labeled YC in China and H07RN-F in Europe, both are often manufactured to meet IEC 60245 benchmarks. These standards dictate the same conductor flexibility (Class 5), insulation thickness, voltage rating (450/750V), and oil/flame resistance tests. As long as the manufacturer holds the relevant certifications (like CE, VDE, or TÜV), the cable is functionally equivalent and safe for global industrial integration.
