IEC62133中电池安全测试设备要求:
今年起(
*,电池使用不当,会导致如烧伤和火灾等事故。近年来电池安全事故频传,美国、日本、俄罗斯等国均强制要求电池按照专门标准进行检测。我国作为电池出口大国,占据一半以上的生产产量。近年来,宁波地区电池产业发展势头迅猛,上百家制造企业中涌现出口不少,已成为浙江省初具规模的电池生产基地,今年1-10月,已有2.35亿美元电池出口顺利出口至美国、欧盟、日本东南亚、中国台湾等各个国家和地区。
电池产业正处于结构升级的关键阶段,积极拓展出口市场意义重大。检验检疫专家指出,获取CB证书的电池产品在申请进口国所要求的其它认证证书时,可免除或减少再送样测试,大大缩短产品进入市场的周期,减少成本费用,加速产品出口。而IEC 62133标准主要包含电芯和电池项目的测试,由于电池的制造和成品检测的复杂性,电池制造企业在检测验证前应对该标准细节有详细了解并在生产中加以控制,如在电芯设计考虑耐持续充电能力,以免在zui终检测中因为不符合IEC 62133标准要求而阻碍出口。
