概述
普通电子电器产品为了符合法律法规要求，一般都是送到试验室进行emc测试，但是，也有一些大型设备、固定式设备、管路很多、需要相应其它的特殊要求进行辅助才能进行相应测试，例如，需要大型锅炉蒸汽、水循环、各类试剂等。这时候就需要EMC现场测试，在企业现场进行EMC测试，这个时候就需要找一家拥有试验室EMC设备租赁服务的试验室，提供EMC外检服务。

EMC现场测试
EMC整改
如果找到一家可靠的的EMC外检服务机构？- 仪器设备是否符合CISPR16的标准要求，是否有校准？
- EMC工程师是否有10年以上工作经验？
- EMC工程师是否有理解标准，熟悉EMC设备仪器操作，梳理数据整理报告的能力？
- EMC工程师是否有现场EMC不合格，有整改的能力，因为时间有限，如果现场没有拥有解决问题的能力，那么就会导致周期延长。
- EMC工程师是否有外检测试的经验，因为外场拥有复杂的电磁环境，必须拥有丰富的外检经验，会灵活排除外界环境干扰，精准定位产品的干扰，这样才能测试精准，符合法律法规的标准要求。
- EMC服务机构能否有对接例如国家试验室机构的经验，这样也会影响项目的执行，甚至导致重测等。
曾工拥有15年以上EMC从业经验，对EMC测试、整改、认证，均有丰富的经验。我们拥有全球顶级的EMC仪器设备，完全符合标准的要求。同样，我们不仅仅有测试能力，我们更有不合格的EMC整改能力，能为客户提供一站式的保姆式服务，免除您的后顾之忧。
