IEC62133中電池**測試設備要求:
今年起(2010年10月26日),電池類產品如欲取得CB認證證書,除按照UL1642測試外,還須進行額外測試,以確保它們符合電池**標準IEC 62133的要求。在特定的過渡期結束后,即從2011年6月27日起,IEC62133標準將**取代UL1642,電池類產品取得CB證書只須符合IEC62133的要求。
眾所周知,電池使用不當,會導致如**和火災等事故。近年來電池**事故頻傳,美國、日本、俄羅斯等國均強制要求電池按照專門標準進行檢測。我國作為電池出口大國,占據全球一半以上的生產產量。近年來,寧波地區電池產業發展勢頭迅猛,上百家制造企業中涌現出口不少知名品牌,已成為浙江省初具規模的電池生產基地,今年1-10月,已有2.35億美元電池出口順利出口至美國、歐盟、日本東南亞、臺灣等各個國家和地區。
電池產業正處于結構升級的關鍵階段,積極拓展出口市場意義重大。檢驗檢疫專家指出,獲取CB證書的電池產品在申請進口國所要求的其它認證證書時,可免除或減少再送樣測試,大大縮短產品進入市場的周期,減少成本費用,加速產品出口。而IEC 62133標準主要包含電芯和電池項目的測試,由于電池的制造和成品檢測的復雜性,電池制造企業在檢測驗證前應對該標準細節有詳細了解并在生產中加以控制,如在電芯設計考慮耐持續充電能力,以免在*終檢測中因為不符合IEC 62133標準要求而阻礙出口。
