This standard is identical with ISO 5199.2002 "centrifugal technical conditions -Ⅱ class" (in English).
This standard is equivalent translation ISO 5199.2002.
For ease of use, this standard has been modified following editorial.
--- "This International Standard" be replaced by "this standard";
"." --- With a decimal point instead of a comma as the decimal point, "";
--- Deleted international standard "foreword";
--- Deleted the international standard "Normative references". "The members of ISO and IEC retain currently valid international standards board
Mind ";
--- Added Appendix A, Appendix B B. Tables 4.6c) and Appendix G G. 1 table title.
--- The ISO 1940-1 This standard referenced in 4.3.2.2 Notes Chapter 2, "Normative references" listed, and gives the
China's national standard correspondence.
This standard replaces GB/T 5656-1994 "centrifugal technical conditions (Ⅱ class)."
This standard compared with GB/T 5656-1994, the main changes are as follows.
--- Original standard in Chapter 3, "maximum load" new standard "design load", respectively, as "design radial load" and "maximum radial negative
Charge ", and an increase in the content;
--- 4.3.2 "Balance and Vibration" increases the maximum allowable vibration intensity provides for vertical pumps;
--- Original Standard Appendix B "peak shift" This standard has been deleted;
--- Original standard Appendix C to "external forces acting on the flange and the outer moment," the new standard in Appendix B as "acting on the spool and the force

Introduction
One of a series of international standards set forth in this standard centrifugal technical conditions; these standards are class Ⅰ, Ⅱ type, Ⅲ class. Class Ⅰ Requirements
The most serious, Ⅲ class requirements of the most loose.
In accordance with the technical requirements of the pump applications to select the level to be used. The selected level to reach a consensus between buyers and sellers.
Also, consider the role of the security requirements of the scene.
However, it is impossible to make use of centrifugal technology for a particular site requirements level standardization, since each has a different use of the site
Claim. All grades (Ⅰ type, Ⅱ and Ⅲ class) can be based on different requirements for pump applications to use. Therefore, it may occur on the basis of class Ⅰ,
Class Ⅱ and Class Ⅲ technical conditions coexist pump manufactured in a factory.
Special applications include industrial or special further technical requirements set forth in a single standard.
Choose a specific application of the pump the desired level, the criteria may include.
---reliability;
--- Operational life requirements;
--- Operating conditions;
--- Environmental conditions;
--- Local ambient conditions.
Those who need or may need to decide by the purchaser and manufacturer/supplier mutually agreed by the buyers of content, its context - Checklist

Centrifugal technical conditions (Ⅱ type)
1 Scope
1.1 standard specifies a single-stage, multi-stage, horizontal or vertical structure general purpose class II and having any of the drivers installed in the form of isolated form
Heart pump technical conditions. Pumps for the chemical process industry (for example, in line with international standards GB/T 5662 requirements of the pump) is set forth in this standard
Typical pump.
1.2 This standard includes with base, coupling and auxiliary piping, including the installation, maintenance and safety-related design features, but does not require the addition
Those conditions associated with its rated output power of something other than the driver.
1.3 In the application of this standard has requested the case and requires a special design feature, you can provide compliance with this standard may be intended for
Generation design, as long as it is described in detail.
Available for consideration by the pump does not fully comply with this standard, as long as will be described for all does not meet the Department.
