  UL vs MET

1. What's the difference between the UL and MET Listed Marks?

The UL and MET marks both indicate that the product has met the minimum requirements of the applicable safety standards. Additionally, both marks validate the product's continued compliance to these standards as evidenced by periodic factory follow-up inspections. The main difference between these two marks is with the level of involvement and partnership between the manufacturer and the test lab. MET does not believe in putting the manufacturer in a defensive mode. MET's safety engineers are customer oriented, and will keep an open line of communication with their client to prevent unnecessary and costly delays.

UL 标志 和MET 标志 之间的差异是什么 ?

UL 和MET 标志两个都指明产品已符合可用的产品安全标准的最低的要求了。另外，这两个标志通过定期的工厂跟踪检查来确保产品持续符合标志要求.这两个认标志的的主要的差异在于介入程度的不同及制造商和试验实验室之间的合作关系的不同。MET不把制造商置于一种防御的工作方式中。MET的安规工程师是以顾客为主导，与客户保持开放畅顺的沟通渠道,以避免造成项目不必要的耽搁,

2.What is an NRTL?

NRTL is a Nationally Recognized Testing Laboratory. In 1970, Congress created OSHA - Occupational Safety and Health Administration to "assure as far as possible every working man and woman in the nation safe and healthful working conditions." In the same year OSHA published its regulation 1910.308(d) stating the electrical equipment would be held acceptable "if it is accepted or certified, or listed, or labelled or otherwise determined to be safe, by a Nationally Recognized Testing Laboratory (NRTL), such as, but not limited to Underwriters Laboratories Inc. and Factory Mutual [Research] Corporation." OSHA did not however provide a means of determining how a lab could gain NRTL status.
MET sued OSHA, three times, which eventually resulted in the creation of a set of criteria to which a lab could prove itself to be worthy of NRTL status. MET in 1988 became the nation's first NRTL, making good OSHA's pledge to undo the "anti-competitive effects" created by its regulations. Thanks to MET Laboratories, manufacturers were freed from the strangle hold of an implied federal monopoly. Consumers are the ultimate benefactors of the improved safety measures in the market that comes with an increase in the number of testing agencies and the outside monitoring of these agencies.

NRTL 是什么？

NRTL 是全国认可的测试实验室。在 1970 年，美国国会创建 OSHA(职业安全和健康管理局)"以确保全国的每个工作的男女都享有安全和有益健康工作的条件。”在同一年, OSHA 出版其规则 1910.308(d) 陈述:如果电气设备是由一个NRTL通过评估确定是安全的即可接受.NRTL可以是但不限于UL实验室和工厂相互调查公司. 然而, OSHA 并没有提供实验室如何能够获得 NRTL 资格的一种方式。

为此,MET实验室总共起诉 OSHA三次，最终促成了实验室获得 NRTL 资格的标准要求的制定。在 1988 年MET成为国家的第一 NRTL，使OSHA成功消除了由其规则所造成的“反竞争的效果”。正是由于MET实验室的努力，制造商们摆脱了一个潜在的联盟垄断的的束缚。市场上测试机构数目的增长及对这些测试机构的外部监控加强,产品安全保证得到不断的改善,而消费者则是其中的最终受益者.


3.Since UL writes the safety standards, don’t manufacturers need to display the UL mark?

The legal requirement is that the laboratory which performs the testing is a Nationally Recognized Testing Laboratory (NRTL) recognized by OSHA. While UL does coordinate standards writing, they are only one of several NRTLs for testing and certification.

既然是使用UL 制定的产品安全标准，制造商不需要在产品上显示 UL 标志吗？

根据法律规定,只有是OSHA认可的NRTL才可以进行产品安全测试.诚然, UL是在标准的制定中发挥了协调作用, 但它的身份仅仅是十几个NRTL实验室之一.因此,如果制造商选择UL之外的NRTL做产品认证, 是不需要在产品中显示UL认证标志的.

4.Do retail stores sell products with the MET Listed Mark?

MET listed products are sold in more than 7000 retail stores throughout the United States. There is no reason why retailers should not accept products bearing the MET Listed Mark. The MET Mark indicates that the product has been evaluated for safety by a approved independent lab in accordance with the national standard. MET is available to provide the necessary information if any retail store requests clarification of the national requirements. Retailers accepting products that bear the MET NRTL Mark include WAL-MART, Best Buy, Lowe's, Home Depot, Radio Shack and CompUSA.

零售商会接受带MET认证标志的产品吗？

通过MET认证的产品在整个美国在超过 7000 个零售的商店销售。零售商是没有任何理由不接受带MET认证标志的产品.  MET认证标志表明 产品已由一个被认可的独立实验室根据国家标准进行评估.如果任何零售商店需要澄清国家对产品认证要求, MET是可以协助提供相关资料的.  以下是接受MET认证标志的著名零售商的部分名单:WAL-MART, Best Buy, Lowe's, Home Depot, Radio Shack and CompUSA.

5.  How does the MET label prove that a product meets the national requirements?

The MET Mark indicates national compliance by virtue of MET's equivalent accreditations to UL and CSA. The MET mark clearly indicates compliance to US and Canadian requirements. At the client's option, the MET mark can specify the applicable UL and/or CSA standard to which the product complies.


MET认证标签怎样证明产品符合全国性的要求？

MET具有与UL和CSA 同等资格的优势,其认证标志表明了产品符合全国性要求.
MET认证标志清楚地表明了产品符合美国和加拿大要求.根据客户的需求,MET认证可以分别按照产品所需顺从的美国和/或加拿大标准来认证.
