Introduction

Fuel hoses are a key component of the boat's permanently fixed fuel system; their quality and performance directly affect the boat's navigation safety and environmental impact.

Environmental safety. GB/T 14652 "Small Boats" specifies the general requirements and physical test methods for fuel hoses, thereby guiding the production and application of fuel hoses.

Inspection. GB/T 14652 "Small Boats" consists of the following two parts based on the fire resistance characteristics of fuel hoses.

---Part 1: Fire-resistant fuel hoses. The purpose is to provide general requirements and physical testing methods for fire-resistant fuel hoses used in small boats.

---Part 2: Non-fire-resistant fuel hoses. The purpose is to provide general requirements and physical testing guidelines for non-fire-resistant fuel hoses used in small boats.

1 Scope

This document specifies the procedures for transporting gasoline, ethanol-blended gasoline, diesel, and fatty acid methyl ester (FAME)-blended diesel on small boats.

General requirements and physical test methods for fire-resistant fuel hoses, applicable to hoses with an inner diameter not exceeding 10 mm and a design working pressure not exceeding 0.34 MPa.

The hose, and the hose with an inner diameter not exceeding 63mm and a design working pressure not exceeding 0.25MPa.

This document applies to hoses in small boats equipped with permanently fixed fuel systems.

Technical requirements for fire-resistant fuel hoses are specified in GB/T 14652.1-2026.Technical requirements for permanently installed fuel systems are specified in [reference needed].

3 Terms and Definitions

The following terms and definitions apply to this document.

Fuels composed of long-chain fatty acid monoalkyl esters extracted from vegetable oils or animal fats.

Note. Compared to pure vegetable oil, fatty acid methyl esters have physical properties closer to fossil diesel fuel, but their properties depend on the type of vegetable oil.
