1、 Comparison Table of Core Testing Standards

Detecting dimensionsChinese StandardInternational/EU standardsCore testing content
Electrical Safety (Low Voltage)GB 4943.1EN 62368-1
UL 62368-1
1. Capacitor discharge (voltage<60V after unplugging for 1 second)
2. Current limiting circuit (no hazardous energy)
Electromagnetic compatibility (EMC)GB/T 17626 seriesIEC 61000-6-2/-4Power frequency magnetic field immunity (near transformer), damping oscillation wave (simulating switch operation)
Environmental ReliabilityGB/T 2423 seriesIEC 60068-2 seriesDouble 85 test (85 ℃/85% RH, simulating outdoor cabinet environment of photovoltaic power station)

DL/T 645 (Electricity Meter)
IEC 61850 (Substation)
IEEE 2030.5
Modbus, MQTT, IEC 104 protocol message timing errors
Functional Safety (Software)GB/T 20438IEC 61508Watchdog reset failure simulation, stack overflow test
cybersecurityGB/T 22239 (Equal Protection)IEC 62443
EN 303 645
Port scanning, fuzz testing, denial of service attack simulation

2、 Stricter testing required for new energy scenarios (different from regular consumer electronics)

The testing standards for ordinary smart home terminals are not applicable here. Smart terminals in new energy environments must pass the following stricter requirements:

test projectseverity levelCorresponding scene
Power frequency magnetic field immunity30 A/m for 1 minuteCommunication box installed near the transformer room and inverter AC side.
Surge (impact) immunityDifferential mode ± 2kV, common mode ± 4kVPhotovoltaic array DC cable coupled with lightning induced waves.
Electrostatic discharge immunityContact discharge ± 8kV, air discharge ± 15kVWhen the operation and maintenance personnel touch the RS485 interface or screen.
High Acceleration Life Test (HALT)-40 ℃~120 ℃ rapid temperature change random vibrationExpose PCB solder joint cracks and crystal oscillator stop defects in advance.

3、 Network Security and Data Integrity (New Strong Regulatory Item)

This is the maximum detection increment that distinguishes intelligent terminals from traditional electrical equipment. According to GB/T 39786 (Network Security Protection of Power Monitoring Systems) and IEC 62443-4-2:

test itemtest methodJudgment requirements
Identity authentication strengthViolent cracking tool attempts to log inProhibit the use of hard coded default passwords (admin/admin), with a failure lock time of ≥ 5 minutes.
Communication integrityIntermediary tampering with meter readings or power commandsTLS 1.2 or above encryption, or the national security SM2/SM4 algorithm, must be enabled.
Firmware reverse protectionRead Flash storage chipThe firmware must be signed and verified, and the JTAG/SWD debugging interface must be physically disabled or fuse locked.
Remote Upgrade (OTA) SecuritySimulate issuing incorrect signatures or low-level firmwareReject downgrade attacks, enter security recovery mode after verification failure.

4、 Specific certification combinations corresponding to typical products

5、 Recent Regulatory Trends Reminder (2025-2026)

  • State Grid/Southern Power Grid Enterprise Standard Upgrade: Intelligent fusion terminals connected to the distribution network are required to pass GB/T 28181 (Video Surveillance Security) or GB 35114 detection to prevent intrusion into the power grid dispatch system through camera ports.

  • EU RED Network Security Authorization Act: Starting from August 2025, smart terminals with wireless functionality exported to Europe must be accompanied by a Network Resilience Act (CRA) compliance statement for CE certification.
