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

Compatibility is fundamentally based on Standard Harmonization. While a cable might be labeled PV1-F in China and H1Z2Z2-K in Europe, both are often engineered to meet the same IEC 62930 or EN 50618 benchmarks. These standards dictate identical performance requirements: a 25-year service life, UV and Ozone resistance, and a temperature range of -40°C to +90°C. As long as the technical data sheet (TDS) confirms compliance with these international benchmarks, the cable is functionally equivalent and safe for global solar projects.
