今年起（2010年10月26日），電池類產(chǎn)品如欲取得CB認(rèn)證證書，除按照UL 1642測(cè)試外，還須進(jìn)行額外測(cè)試，以確保它們符合電池安全標(biāo)準(zhǔn)IEC 62133的要求。在特定的過(guò)渡期結(jié)束后，即從2011年6月27日起，IEC 62133標(biāo)準(zhǔn)將全面取代UL 1642，電池類產(chǎn)品取得CB證書只須符合IEC 62133的要求。

*，電池使用不當(dāng)，會(huì)導(dǎo)致如燒傷和火災(zāi)等事故。近年來(lái)電池安全事故頻傳，美國(guó)、日本、俄羅斯等國(guó)均強(qiáng)制要求電池按照專門標(biāo)準(zhǔn)進(jìn)行檢測(cè)。我國(guó)作為電池出口大國(guó)，占據(jù)一半以上的生產(chǎn)產(chǎn)量。近年來(lái)，寧波地區(qū)電池產(chǎn)業(yè)發(fā)展勢(shì)頭迅猛，上百家制造企業(yè)中涌現(xiàn)出口不少，已成為浙江省初具規(guī)模的電池生產(chǎn)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(guó)、歐盟、日本東南亞、中國(guó)臺(tái)灣等各個(gè)國(guó)家和地區(qū)。

電池產(chǎn)業(yè)正處于結(jié)構(gòu)升級(jí)的關(guān)鍵階段，積極拓展出口市場(chǎng)意義重大。檢驗(yàn)檢疫專家指出，獲取CB證書的電池產(chǎn)品在申請(qǐng)進(jìn)口國(guó)所要求的其它認(rèn)證證書時(shí)，可免除或減少再送樣測(cè)試，大大縮短產(chǎn)品進(jìn)入市場(chǎng)的周期，減少成本費(fèi)用，加速產(chǎn)品出口。而IEC 62133標(biāo)準(zhǔn)主要包含電芯和電池項(xiàng)目的測(cè)試，由于電池的制造和成品檢測(cè)的復(fù)雜性，電池制造企業(yè)在檢測(cè)驗(yàn)證前應(yīng)對(duì)該標(biāo)準(zhǔn)細(xì)節(jié)有詳細(xì)了解并在生產(chǎn)中加以控制，如在電芯設(shè)計(jì)考慮耐持續(xù)充電能力，以免在zui終檢測(cè)中因?yàn)椴环螴EC 62133標(biāo)準(zhǔn)要求而阻礙出口。
