标准差异分析报告

CISPR11:2003+AMD1:2004+AMD2:2006为最新版本的CISPR标准，其与CISPR11 :2003的主要技术差异如下：
一、    条款：1.1范围和目的
内容比较：
CISPR11:2003    CISPR11:2003+AMD1:2004+AMD2:2006
Requirements for ISM lighting apparatus operating in the ISM frequency bands of 915 MHz(only allowed in region 2 as defined by the ITU Radio Regulations),2.45GHz and 5.8GHz are contained in the standard.    Requirements for ISM lighting apparatus and UV irradiators operating at frequencies within the ISM frequency bands defined by the ITU Radio Regulations are contained in this standard.
标准差异：适用范围增加了工科医频段范围内紫外线辐射器，扩大了标准的适用范围，旧版将ITU规定的工科医频率具体化，新版标准笼统地加以表述。
二、    条款：1.2 引用标准
标准差异：新版标准增加CISPR16-4-2:2003
三、    条款：5.1.2.2 家用或商业用途的感应炊具
内容比较：

CISPR11:2003+AMD1:2004+AMD2:2006

标准差异：新版标准修改了家用或商用感应炊具的限值表2c——感应器具的电源端骚扰电压，放宽了额定电压100V且无接地连接装置的感应炊具的电源端骚扰电压限值。
四、    条款：5.2.3 1GHz~18GHz频段
内容比较：
CISPR11:2003    CISPR11:2003+AMD1:2004+AMD2:2006
Class A equipment
Limits are under consideration.
Class B equipment    无对应内容
标准差异：在随后的限值表中都给出了明确的名称，此处为编辑行修改。

五、    条款：5.2.3 1GHz~18GHz频段  表6
内容比较：
CISPR11:2003

CISPR11:2003+AMD1:2004+AMD2:2006

标准差异：适用设备范围扩大，新版表6同样适用于2组A类设备，限值不同。
六、    条款：6.5.4 微波炊具
内容比较：
CISPR11:2003    CISPR11:2003+AMD1:2004+AMD2:2006
The water container shall be made of electrically non-conductive material such as glass or plastic (for example, the container defined in Clause 8 of IEC 60705 may be used).
   The water container shall be a cylindrical container of borosilicate glass of an external
diameter of 190 mm ± 5 mm and a height of 90 mm ± 5 mm.
Before the measurement, preliminary operation of the microwave oven under test shall be performed until the magnetron oscillating frequency is stabilized. More than 5 min preheating time is required.
无对应内容    NOTE During the measurement, the water load should be exchanged to cold water before it starts to boil.
标准差异：新版标准将IEC 60705中第8章的有关要求摘录出来，并做了更加具体化的规定，增加了试验的可操作性。
七、    条款：6.5.6 单/多区感应炊具
内容比较：CISPR11:2003+AMD1:2004+AMD2:2006增加了以下内容：
Cooking zones which are not intended for use with even vessels (e.g. wok-zones) shall be measured with the vessel provided together with the hob, or with the vessel recommended by the manufacturer.
标准差异：增加了对于不用于平底容器的感应区域，做试验时应采用制造商推荐的容器或铁架，增加了试验的可操作性。
八、    条款：6.6测量场地的记录
内容比较：CISPR11:2003+AMD1:2004+AMD2:2006增加了以下内容：
6.6 Recording of test-site measurement results
Any results obtained from measurements of conducted and/or radiated radio-frequency disturbances shall be recorded in the test report. If the results are not recorded in a continuous way and/or in graphical form over the frequency range observed, then the minimum requirements for the recordings set out in 6.6.1 and 6.6.2 shall apply.
In addition, the test report shall include the measurement instrumentation uncertainty as
specified in CISPR 16-4-2
6.6.1 Conducted emissions
Of those conducted emissions above (L – 20 dB), where L is the limit level in logarithmicunits, the record shall include at least the disturbance levels and the frequencies of the six highest disturbances in each observed frequency band from each mains port belonging to the EUT. The record shall also include an indication of which conductor of the mains port carried the observed disturbance(s).
6.6.2 Radiated emissions
Of those radiated emissions above (L – 20 dB), where L is the limit level in logarithmic units, the record shall include at least the disturbance levels and the frequencies of the six highest disturbances in each observed frequency band. The record shall include the antenna polarization, antenna height and turntable rotation position if applicable for each reported disturbance. In case of test site measurements, the measurement distance actually selected and used (see 5.2.2) shall also be recorded in the test report.
标准差异：新版标准增加了场地测量记录的有关要求。对传导和/或射频辐射骚扰的测量结果，原则上都应记录在测试报告中。如果测量不连续，则报告中应按照6.6.1和6.6.2中的最低要求进行记录，并应给出测量仪器的不确定度。
传导发射：对于传导发射高于限值20dB的传导发射，记录中应至少包括6个最高骚扰产生的频率和对应的骚扰电平。如有不同电源端口，则每个端口都须如此记录，且记录应标明对应关系。
辐射发射：对于辐射发射高于限值20dB的辐射发射，记录中应至少包括6个最高骚扰产生的频率和对应的骚扰电平。记录应包括该6个点对应的天线极化方向、天线高度、转台旋转到的位置，并应注明实际的测量距离。
九、    条款：11.4 测量不确定度
内容比较：CISPR11:2003+AMD1:2004+AMD2:2006增加了一下内容：
11.4 Measurement uncertainty
The results of measurements of emissions from ISM equipment shall reference the measurement instrumentation uncertainty considerations contained in CISPR 16-4-2.
Determining compliance with the limits in this standard shall be based on the results of the compliance measurement, not taking into account measurement instrumentation uncertainty. However the measurement uncertainty of the measurement instrumentation and its associated connections between the various instruments in the measurement chain shall be calculated and both the measurement results and the calculated uncertainty shall appear in the test report.
NOTE For in-situ measurements, the contribution of uncertainty due to the site itself is excluded from the uncertainty calculation.
标准差异：明确要求测试报告中应给出测量不确定度。
十、    条款：附录A
标准差异：新版标准中2组设备增加UV辐射设备，与适用范围相对应。
