近日，马来西亚能源委员会调整了强制性认证电子电器类产品清单，电子电器类强制性认证产品将从现有的31类增加至34类，主要是增加了空调、适配器/充电器、按摩器三类产品，将电吹风更换为蒸发器，驱蚊器更换为电动剃须刀两类产品。新增加产品的强制性认证将自2013年1月1日生效。 马来西亚电子电器产品认证的法律依据有两个：《电力供应法(1990)》和《电器设备批准条例(1994)》，这两个法律都由能源委员会执行。前者针对电力供应规定了电力安装的许可和控制、配送电力设备的安全以及保护人身安全等方面的要求，后者则规定了任何制造商、进口商、展览商、销售商和广告商的电器产品必须保证符合标准要求，获得认可证书(COA)，并加贴SIRIM标签/标志，否则就不能在马来西亚市场上销售。在COA期满前14天，电器产品的制造商、进口商、展览商和广告商必须提出对COA进行复审的申请。 根据《电器设备批准条例(1994)》的规定，产品进行认证依据的标准主要是国家标准和等同采用的IEC标准，有的产品甚至直接使用IEC标准。对此，检验检疫部门提醒相关企业：一是及时按要求完成企业产品的强制性认证，做好前置工作;二是在产品生产过程中严格按照IEC标准生产，因为马来西亚电子电器类产品认证的相关标准大部分是采用IEC标准，即使部分采用国家标准，也是以IEC标准为基础修订的;三是加强与检验检疫机构沟通，及时了解相关标准变更情况;四是积极开拓新兴市场，规避风险。
