GB 14536.9-2008/IEC 60730-2-8:2003 IEC Foreword

1) IEC (International Electrotechnical Commission) is a worldwide standardization group composed of national electrotechnical committees (IEC National Committees) Organizations. The object of IEC is to promote international cooperation on issues related to the standardization of the electrical and electronic fields. For this purpose IEC addition to other activities, but also publishes International Standards. These standard-setting work is entrusted to technical committees Completed. As a member of IEC National Committees, as long as the interest of the standard to be developed, may participate in the development of its work Make. Liaising with the IEC 's international, official or unofficial organizations are also involved in the development of standards. IEC and the World Organization for Standardization (ISO ) in accordance with the conditions specified in the agreement, close cooperation.

2) since each technical committee has representatives from the National Commission on the relevant issues of interest, so the IEC on technical Issue formal decisions or agreements on the maximum expression of the international consensus on the relevant issues.

3) documents generated in the form of recommendations for international use, and standards, technical specifications, technical reports or guidelines published in the form, and National Committees in that sense of acceptance.

4) In order to promote international unification, IEC National Committees in charge of the IEC international standards transparently converted to the maximum extent possible National or regional standards. Between the IEC Standard and the corresponding national or regional standard if there is any difference, it should be converted into the standard After clearly illustrates.

5) IEC did not develop any signs of approval procedures, in case a device is declared in conformity with an IEC standard is, this is not IEC Accountable.

6) It is noteworthy that this International Standard may involve some parts of the patent. IEC for the identification of some or all of this A Class of the patent will be irresponsible.

IEC 60730-2-8 international standard by the IEC TC72. home automation controller Technical Committee.

The IEC 60730-2-8 standard enhanced version based on the second edition (2000) [documents 72/428/FDIS and 72/439/RVD] and Amendment One (2002) [documents 72/553/FDIS and 72/557/RVD].

It constitutes 2.1 version.

The vertical bar represents the margin here in the original version of the revision has been a modification.

According to this publication section ISO/IEC Guide to the drafting of the third.

Part 2 of this article should be used in conjunction with IEC 60730-1. It is based on IEC 60730-1 third edition (1999) formed the basis of. IEC 60730-1 should be considered in future editions or revised pieces.

The first part 2 supplements or modifies the corresponding provisions of IEC 60730-1, to make it into the IEC standard. Safety requirements for electrically operated water valves (Including mechanical requirements).

Part 2, where marked "increase", "modification" or "replacement" of the place, in Part 1 of the corresponding requirements, test specifications or comments should be Amended accordingly.

Where the need to modify the Department, Part 2 will be indicated in the corresponding provisions of Part 1 is applicable.

The development of international standards, each country must be considered in all regions due to the different requirements of the actual situation formed, and each country should be recognized Electrical systems and wiring codes family differences.

In Part 2 of this article, note the differences in different countries in order to give "in some countries" form; see these differences.
