NRTL

NRTL

NRTL即指国家认可实验室，是英文Nationally Recognized Testing Laboratory的缩写，美国劳工部下属的职业安全和健康管理局(OSHA)要求在工作场合所使用的产品必须经国家认可实验室测试并发证以保证使用者的人身安全。

在北美，制造商在市场上合法销售民用或工业用的产品就必须按照国家的标准对其进行严格的测试。只有通过了国家认可实验室(NRTL)的相关测试，该产品才能在市场上合法销售。

美国OSHA官方网站列出所有的NRTL

• Canadian Standards Association (CSA) (also known as CSA International)
• Communication Certification Laboratory, Inc. (CCL)
• Curtis-Straus LLC (CSL)
• FM Approvals LLC (FM) (formerly Factory Mutual Research Corporation)
• International Association of Plumbing and Mechanical Officials EGS (IAPMO)
• Intertek Testing Services NA, Inc. (ITSNA) (formerly ETL)
• MET Laboratories, Inc. (MET)
• NSF International (NSF)
• QAI Laboratories, LTD (QAI)
• QPS Evaluation Services, Inc. (QPS)
• SGS U.S. Testing Company, Inc. (SGSUS) (formerly UST-CA)
• Southwest Research Institute (SWRI)
• TUV Rheinland PTL, LLC (TÜVPTL)
• TUV SUD America (TÜVAM)
• TUV SUD Product Services GmbH (TÜVPSG)
• TUV Rheinland of North America (TÜV)
• Underwriters Laboratories Inc. (UL)

值得注意的是，很多人误认为UL认证是强制性认证，但实际上UL只是NRTL之一。美国安全认证更加准确来说应该说是“NRTL认证”，而不是“UL认证”。以上任何一家机构出的北美安全认证都属于NRTL，即北美安全认证。
