FCC SDOC

From 认证百科

什么是FCC

美国联邦通信委员会,英文名称为:FCC( Federal Communications Commission),是一家独立的政府机构,直接对美国国会负责,于1934年由COMMUNICATION ACT建立,它负责常规的州际、国际通信,如:电视机,电线、卫星、电缆方面的工作,涉及美国50多个州、哥伦比亚以及美国所属地区,为确保与生命财产有关的无线电和电线通信产品的安全性。

FCC SDOC

美国FCC SDOC是指Supplier's Declaration of Conformity,即 Supplier’s Declaration of Conformity ,简称SDoC。设备供应商(注:该供应商必须是美国当地的公司)将对符合规定标准或要求的设备进行检测,符合规定的设备需提供相关文件(如 SDoC 的声明文件)向公众提供证明。 SDoC 政策简化了之前繁复的 FCC 认证要求,进一步减轻了企业的负担。

FCC SDOC

SDoC 政策措施如下:
  • 简化自我审批的程序。FCC 决定用 SDoC 形式替代现有的 FCC VoC 和 FCC DoC 。
  • 允许使用电子标签。 FCC 规定使用电子标签,所需信息须显示在产品上或以其他方式提供的产品上,如 FCC 识别号码和符合性声明。
  • 减轻繁琐的进口声明和要求。该命令不再需要向 Customs and Border Protection (CBP)提交 RF 设备的美国进口声明,并对委员会规则进行修改,以澄清与进口设备相关的合规性要求。
  • 重新修订测量程序和澄清标准。该命令修改了委员会的测量程序,以简化和整合不同服务中设备的使用要求,使之更具灵活性。
该政策在公布之日即 2017 年 11 月 2 日起已生效,但仍有一年过渡期,过渡期内可选择继续使用 FCC VoC 和 DoC 认证程序;过渡期前做的 FCC VoC 和 DoC 认证程序是始终有效的,如果产品有修改,则需重新认证;通过 FCC SDoC 认证程序的产品将可自主选择标记或不标记 FCC logo;SDoC 要求增加符合声明文件到设备随附文件中,符合声明需包含:美国当地供应商的名称、地址或联系网址等必要信息。
SDOC认证,是指所有去美国的电子电器等产品,均需要符合美国FCC PART 15B即之前的所有符合FCC VoC 和 FCC DoC的全部电子电器产品。


FCC SDoC的变化

  • 对产品负责人有明确要求, 需要提供美国公司的联系方式, 责任方可以是进口商或收货人或报关行, 同时2018年11月2日之后,FCC DOC和FCC VOC作废;
  • 所有SDoC产品可以自主选择是否标识FCC Logo;
  • 我们常见的设备的认证方式发生重大变化, 除无线发射产品/扫描接收机/电力线宽带接入/雷达探测产品必须要做FCC ID, 其他所有产品都可以选择FCC ID或者SDOC。

SDoC产品范围

申请FCC认证中,FCC SDoC适用于普通不带无线功能的产品,如显示器、普通家用电器、灯具等。包含个人电脑及其周边设备;家用电器设备;电动工具;音视频产品;灯具;玩具;安防类产品等。如显示器、鼠标、电冰箱、电水壶、吹风机、LED灯具、电子玩具、普通门禁等产品。

FCC铭牌、标签、说明书

FCC警告语

A类数字设备或外设的用户使用说明书的显著位置印有以下声明或类似的声明:
Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.
B类数字设备或外设的用户使用说明书的显著位置印有以下声明或类似的声明:
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
* —Reorient or relocate the receiving antenna.
* —Increase the separation between the equipment and receiver.
* —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
* —Consult the dealer or an experienced radio/TV technician for help.

如果设备是由多个数字设备组成,以上两段声明只需要包含在主控制单元的使用说明书中即可。如果说明书或用户手册不是以纸质方式提供的,而是以磁盘、互联网等方式提供,以上的声明也应以相应方式提供给用户。

FCC SDOC的铭牌和说明书上分别要有警告语:(如果铭牌太小可不加)

标签或产品说明书中应具有相关类似描述:
  • This device complies with Part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference.(适用于如Part 73的无线电广播设备等无线电广播接收装置)
  • This device is verified to comply with Part 15 of the FCC Rules for use with cable television service.(适用于电缆线及其连接器等)
  • This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.(其他所有设备)
 注:如果设备是由电线连接的两个或两个以上部分组成,以上标签应加贴在主要控制单元上。如果设备太小,不能加贴以上陈述内容,则必须在设备包装或说明书中体现以上陈述内容。

FCC的A级或者B级

§ 15.3 Definitions.

(h) Class A digital device. A digital device that is marketed for use in a commercial,industrial or business environment,exclusive of a device which is marketed for use by the general publicor is intended to be used in the home.

(h) A类数字设备。销售用于商业、工业或商业环境的数字设备,不包括面向公众销售或打算在家中使用的设备。

(i) Class B digital device. A digital device that is marketed for use in a residential environment notwithstanding use in commercial, business and industrial environments. Examples of such devices include, but are not limited to, personal computers, calculators, and similar electronic devices that are marketed for use by the general public.

B类数字设备。一种数字设备,在商业、商业和工业环境中使用,但在住宅环境中使用。此类设备的示例包括但不限于个人计算机、计算器和用于向公众使用的类似电子设备。

NOTE: The responsible party may also qualify a device intended to be marketed in a commercial, business or industrial environment as a Class B device, and in fact is encouraged to do so, provided the device complies with the technical specifications for a Class B digital device. In the event that a particular type of device has been found to repeatedly cause harmful interference to radio communications, the Commission may classify such a digital device as a Class B digital device, regardless of its intended use.

注:责任方还可以将打算在商业、商业或工业环境中销售的设备限定为 B 类设备,并且实际上鼓励此类设备使用,前提是该设备符合 B 类数字设备的技术规范。如果发现某种类型的设备反复对无线电通信造成有害干扰,委员会可以将此类数字设备归类为 B 类数字设备,而不管其预期用途如何。

FCC SDOC传导发射限值

(a) Except for Class A digital devices, for equipment that is designed to be connected to the public utility (AC) power line, the radio frequency voltage that is conducted back onto the AC power line on any frequency or frequencies within the band 150 kHz to 30 MHz shall not exceed the limits in the following table, as measured using a 50 μH/50 ohms line impedance stabilization network (LISN). Compliance with the provisions of this paragraph shall be based on the measurement of the radio frequency voltage between each power line and ground at the power terminal. The lower limit applies at the band edges.

除A类数字设备外,对于设计为连接到公用设施(AC)电源线的设备,在150 kHz至30 MHz的频段内任何频率或频率上传回交流电源线的射频电压不得超过下表中的限值,如使用50 μH/50欧姆线阻抗稳定网络(LISN)测量的。符合本款规定的依据应基于对电力终端各电源线和接地之间的射频电压的测量。

典型一问一答

1,灯具产品是做A级还是做B级呢? 答:依据标准灯具如果是安装在家里面则必须满足B级限值要求,如果是安装在户外、工业环境的设备则可以用A级限值要求。

2,FCC Part 15的B级容易合格 还是 FCC Part 15的A级容易合格呢? 答:依据标准里面规定的限值所知,A级的限值是明显高于B级的限值,也就是说同一个样品的情况下A级更容易合格。

3,FCC的测试数据的A级、B级可以互换吗?数据如果测试完了B级,假如B级不符合要求,那么还能换成A级吗? 答:当然可以互换的,数据不会改变,改变的只是限值,一般测试软件很容易实现A级、B级限值的互换,具体与测试工程师确认沟通。举个例子,你与姚明比身高、以及与大张伟比身高,你的高度是不变的,变的只是参考。
