關於EN 61800-3:2004當中的問題
3.2 Intended use3.2.1
first environment
environment that includes domestic premises, it also includes establishments directly connected without intermediate transformers to a low-voltage power supply network which supplies buildings used for domestic purposes
NOTE Houses, apartments, commercial premises or offices in a residential building are examples of first environment locations.
3.2.2
second environment
environment that includes all establishments other than those directly connected to a lowvoltage
power supply network which supplies buildings used for domestic purposes
NOTE Industrial areas, technical areas of any building fed from a dedicated transformer are examples of second environment locations.
3.2.3
PDS of category C1
PDS of rated voltage less than 1 000 V, intended for use in the first environment
3.2.4
PDS of category C2
PDS of rated voltage less than 1 000 V, which is neither a plug in device nor a movable device and, when used in the first environment, is intended to be installed and commissioned only by a professional
NOTE A professional is a person or an organisation having necessary skills in installing and/or commissioning power drive systems, including their EMC aspects.
3.2.5
PDS of category C3
PDS of rated voltage less than 1 000 V, intended for use in the second environment and not
intended for use in the first environment
3.2.6
PDS of category C4
PDS of rated voltage equal to or above 1 000 V, or rated current equal to or above 400 A, or
intended for use in complex systems in the second environment
以上是從EN 61800-3:2004當中挑選出來的，想請教各位在上面提到的first environment及second environment是否與底下的C1、C2、C3、C4中所提到的環境有關聯？還是說C1、C2、C3、C4這些是指測試條件環境，而上面的first environment及second environment講的是用途條件，因此兩者是無關聯性？
舉例來說：我們變頻器屬於工業用，因此在歸類時屬於second environment，但是我們要求產品測試必須通過C2甚至是C1，這兩者間所提到的first environment及second environment是否有相對關聯性？謝謝。 没读过这个标准，帮你顶顶！ 引用第1楼ds1983于2007-07-31 14:57发表的:

感謝，希望能夠有人能解決疑問~ 還是沒有人回應~ 想下载这个标准，不知楼主可否分享一下？ 引用第4楼szhwl于2007-08-01 14:59发表的:

本来想帮你加亮提前一下，可是系统说我无权管理总版主的帖子。。。 沒關係，畢竟會用到這部份標準的也不知道多不多，只是看到內容有這部份的疑問，所以上來發問看是不是有人能夠回答我這部份的問題~ first environment及second environment是否與底下的C1、C2、C3、C4中所提到的環境有關聯？
——有关联，C1/C2是用在first environment中，C3/C4是用在second environment中（定义中很明确）
舉例來說：我們變頻器屬於工業用，因此在歸類時屬於second environment，但是我們要求產品測試必須通過C2甚至是C1，這兩者間所提到的first environment及second environment是否有相對關聯性
——许多厂家对产品的性能要求并不是按标准走的，你们的产品应该属于C3或C4（具体看额定电压是多少），但要求通过C2甚至C1可能是你们对产品的EMI控制更严格吧，呵呵，许多公司都这样的，要求传导和辐射的限值线是6dB below CISPR22 class B。另外，虽然C1/C2的EMI比C3/C4严格，但EMS却是C3/C4等级更高些。
