Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

This document replaces GB/T 4795-2009 "15ppm Bilge Water Separator". Compared with GB/T 4795-2009, except for structural adjustments and In addition to editorial changes, the main technical changes are as follows.

---The name of test liquid A is changed to residual marine fuel oil, and the name of test liquid B is changed to marine distilled fuel oil (see 5.5.2.1, 2009 version 6.1.2.1);

---The relative densities of test liquid A, test liquid B, and test fresh water are changed to density (see 5.5.2.1, 6.1.2.2 of the 2009 edition);

---The accuracy level of flow meters, pressure gauges and thermometers is changed to level 1.6 (see 5.5.1.9~5.5.1.11, 6.1.1.9~ of the 2009 edition 6.1.1.11);

--- Added requirements and test methods for the insulation resistance test, withstand voltage test, and power supply fluctuation test of the separator (see 4.3.3~ 4.3.5, 5.8~5.10);

---Added the environmental adaptability requirements and test methods of separators (see 4.4.1~4.4.4, 5.14~5.18).
