This Standard modifies and adopts API/IP 1581.2002 “Specifications and
qualification procedures for aviation jet fuel filter/separators” (English version). This Standard, according to API/IP 1581.2002, is redrafted. For comparison purposes, a table for comparison of the clauses of this Standard and the clauses of API/IP 1581.2002 is listed in informative Appendix A.
Due to the legal requirements of China and the special needs of industry, this Standard, when adopting API/IP 1581.2002, makes some modifications. A table of detailed technical differences and their causes is given in Appendix B for reference.
For ease of use, the following editorial changes have been made to this Standard.
- The word “this Specifications” is changed to “this Standard”;
- REPLACE the comma “,” as a decimal point with the decimal point “.”;
- DELETE the foreword of API/IP 1581.2002 standard.
Appendix A and Appendix B of this Standard are informative appendixes. The Appendix C, Appendix D, Appendix E, Appendix F, and Appendix G are
normative appendixes.
This Standard was proposed by China Machinery Industry Federation.
This Standard shall be under the jurisdiction of National Technical Committee on Separation Machinery of Standardization Administration of China.
Drafting organizations of this Standard. China National Aviation Fuel Group Limited, Beijing Chengtian Beida Filtration Technology Co., Ltd.
Main drafters of this Standard. Zhang Hu, Liang Lijie, Zhao Zhong, Bai Jing, Li Ming, Hou Hairui, Deng Binghua.
This Standard is issued for the first time.
Specifications for aviation jet fuel filter/separators
1 Scope

3 Terms and definitions
The following terms and definitions apply to this Standard.
3.1 Filter/separator
A vessel containing filter/coalescer and separator elements which can
continuously remove dirt and water from aviation jet fuel.
Note 1. A filter/separator can have either a vertical or a horizontal configuration. Note 2. A filter/separator can be two or multiple stages. A two-stage system consists of filter/coalescer and separator elements contained within a vessel. The fuel flows through the filter/coalescer element(s) into the vessel and then flows through the separator element(s) to exit the vessel. A multi-stage system, based on the two- stage system, adds one or more additional stages. Additional stages may include devices (or adsorption stage) installed within separator element capable of shutting off fuel flow if the water content exceeds the specified value. Additional stages may also include prefilter devices installed within coalescer element capable of removing particulate contaminant.
