적용 범위

This standard specifies the general safety requirements, inspection rules, and testing methods for resistance welding machines and their associated controllers. It applies to equipment powered by voltages not exceeding those specified in GB/T 156, including stationary, portable, and handheld resistance welding machines used in similar welding processes. It is mandatory for all manufacturers producing resistance welding equipment for the Chinese market.

기술 요구 사항

The standard comprehensively outlines the safety criteria for resistance welding equipment, covering electrical, thermal, and mechanical aspects. It specifies stringent requirements for insulation coordination, including minimum clearances and creepage distances based on overvoltage categories and pollution degrees. Manufacturers must ensure compliance with dielectric strength limits and proper connection to protective conductors. For thermal performance, the standard defines temperature rise limits for windings, welding circuits, and accessible surfaces under specific duty cycles. It mandates that liquid cooling systems and pneumatic/hydraulic systems operate reliably under defined pressure parameters without leakage. Equipment must also incorporate mechanical hazard protections and emergency stop functions. Additionally, the standard sets forth requirements for power supply switches, residual current devices (RCDs) for handheld equipment, and component compliance. Comprehensive documentation, including user manuals and durable nameplates with specified electrical ratings, is strictly required.

시험 방법

The standard mandates both type tests and routine tests to verify compliance. Key testing procedures include dielectric strength tests using AC or impulse voltages, insulation resistance measurements, and temperature rise tests utilizing resistance methods or embedded sensors. Manufacturers must also conduct sealing tests for cooling, pneumatic, and hydraulic systems under elevated pressures. Routine tests are required on every production unit to verify general visual integrity, protective conductor connections, and dielectric strength.

자주 묻는 질문

What products are regulated under GB 15578-2008?

The standard applies to resistance welding machines and controllers powered by voltages not exceeding those specified in GB/T 156, including stationary, portable, and handheld types. It excludes electromagnetic compatibility (EMC) requirements.

Are there any major updates from the previous version, GB 15578-1995?

The 2008 version significantly expanded the scope beyond the original single-phase AC machines. It introduced new requirements for clearance and creepage distances, protective conductor connections, RCDs, and component compliance. Manufacturers previously certified to the 1995 version must update their compliance to meet these mandatory new criteria.

How does GB 15578-2008 differ from international IEC standards?

The standard incorporates definitions and methodologies from multiple IEC standards, such as IEC 60664-1 for insulation coordination and IEC 60529 for IP codes. However, it establishes specific Chinese compliance thresholds and testing parameters tailored to domestic safety requirements.

The summary above provides a high-level overview of GB 15578-2008. To ensure complete compliance for your products entering the Chinese market, a precise and professional translation of the full technical specifications is essential.
