Q.IEC是什么组织?
Founded in 1906 the Internationa Electrotechnical Commission (IEC) is the world organization that prepares and publishes international standards for all electrical electronic and related technologies. The IEC was founded as a result of a resolution passed at the International Electrical Congress held in St.Louis (USA) in 1904. The membership consists of more than 50 participating countries including all the world's major trading nations and a growing number of industrializing countries.

There are two forms of active participation in the IEC's work. Full membership gives countries the possibility of fully participating in international standardization activities. Full members are National Committees each having equal voting rights. Associate membership allows for limited participation of countries with limited resources. Associate members have observer status and can participate in all IEC meetings. They have no voting rights.

On becoming a member of the IEC each National Committee agrees to open access and balanced representation from all private and public electrotechnical interests in its country. The whole organization of the IEC is designed to ensure that the National Committees play a leading part in all decision-making instances of the Commission. This enables the widest degree of consensus on standardization work to be reached at an international level. It is up to the National Committees to align their policies accordingly at the national level.

In addition a Pre-Associate "membership" status provides countries with support in forming a national electrotechnical committee from the IEC Central Office or any neighbouring full member National Committee with the aim of becoming Associate members within five years.
Q.CB体系是什么?
CB检验为一全球性相互体系,全世界有四十三个会员国,共五十四个NCB(国际验证机构)参与CB Scheme。在共同的IEC标准下,各验证单位均相互承认彼此核发之CB报告,并可据此核发给当国或该机构之产品安全验证的证书或证
CE标示是什么
CE标示是产品进入欧盟境内销售的通行证。为欧盟所推行的一种安全标示,但非的安全标志。CE标示表明该产品符合一项或多项欧市现行调和指令,对安全、健康及环境的基本要求。
UL标志是什么?
UL为美独立且非盈利的产品安全检验机构,且为美国标准的制定者,UL标志为产品进入美国境内销售的通行证。
德国产品安全标志为欧洲许多的买主及消费者所肯定。因此即使欧市已实施统一的CE标示,GS标志仍有无可取代的市场价值。

IEC 60950-1 (2001-10) Safety of information technology equipment
2005年4月1日起,UL/C-UL全面采用CSA/UL
UL (Underwriters Laboratories) 于2003年4月1日公布针对信息科技设备制定的安全标准: CSA C22.2 No. 60950-1/UL 60950-1初版。 CSA C22.2 No. 60950-1/UL60950-1以2001年10月公布的欧盟指引IEC 60950初版为基础,是美加两国共享的标准,已获美国标准协会(ANSI)及加拿大标准委员会(SCC)认可,而且实时获IECEE CB体系采用。由2003年4月1日起,所有提交UL申请UL及/或UL加拿大(C-UL)的信息科技产品,制造商皆要求采用CSA/UL 60950第三版作为测试标准,否则UL会依据CSA/UL 60950-1标准为产品进行评估测试。但2005年4月1日以后,将会全面采用CSA/UL 60950-1标准进行。
2.1.1.5新标准列明危险能源值(Hazardous Energy Levels)在60秒之后测量。
2.4.2限流電路(Limited Current Circuit)测量的部分,附件D说明接触电流测量仪器可以作为2 k ohm 无感电阻的替代方案,以便测量复合波(complex waveform)。
附件 NAE (2.7.1)澄清15 A 级的插座(NEMA 5-15R)如果设置于使用者可能接触的范围,或可使用20 A 断路器作保护。D1National Difference)
