The following parameters outline testing procedures for lightning-induced surges and power fault events: Surge requirements: 100 A 10x1000 waveform 10 A, 50 Hz, 1 s 5 A, 50 Hz, 30 s 260 V on 100 kV/s 400 V on 1 kV/s Temperature limits: -40 to 65 C Insulation leakage requirements: 0.1 A @ 100 V dc Maximum load capacitance: 200 pF The following is actual text of the circular from the Certification and Accreditation Administration of the People's Republic of China (CNCA). by the Certification and Accreditation Administration of the People's Republic of China (CNCA) December 3, 2001 Circular Relevant to the Implementation of the Compulsory Product Certification System The Compulsory Product Certification System (CPCS) is jointly announced for statutory implementation by the State General Administration for Quality Supervision and Inspection and Quarantine of the People's Republic of China (AQSIQ) and the Certification and Accreditation Administration of the People's Republic of China (CNCA). This new system consists of Regulations for Compulsory Product Certification, Regulations for Compulsory Product Certification Mark, and the First Catalogue of Products Subject to Compulsory Certification (hereinafter referred to as the Catalogue), and so on. The Old System, namely, the Safety License System for Import Commodities administered by the former State Administration for Entry- Exit Inspection and Quarantine of the People's Republic of China (CIQ), and the Compulsory Supervision System for Product Safety Certification administered by the former China State Bureau of Quality and Technical Supervision (CSBTS), will be replaced. The following circular is announced concerning the transition from the Old System to the New System. Regulatory Requirements (continued) Certification and Accreditation Administration of the People's Republic of China
