ISO 19013-1 Rubber Hoses and Piping for Internal Combustion Engines and Fuel Circuits - Part 1: Diesel Fuels

Developed by the International Standards Organization (ISO), this part of the ISO 19013 standard specifies requirements for rubber tubing and hoses used in diesel fuel circuits for internal combustion engines. The diesel fuels covered include biodiesels composed of the methyl ester of rapeseed oil at levels up to 20% by volume in conventional diesel fuels.

This document can also be applied as a classification system for original equipment manufacturers (OEMs) to provide elaboration of a line call of tests for certain applications not covered by the specified major types. In this case, the hose or tubing will not bear any markings indicating the number of this document, but may detail the OEM's own identification markings as shown in the parts drawings.

The product shall consist of integrally reinforced or unreinforced extruded rubber materials, which may or may not be preformed before final vulcanization. The product also has improved fluid resistance and/or reduced fuel vapor permeability.
It may also have a rubber or thermoplastic barrier layer forming the inner liner or as an inner layer to provide added protection.

Here are seven hose and tubing systems for specific applications:

• Type 1 Class A = Pressurized [7 bar (0,7 MPa) working pressure] supply and return lines from fuel tank to fuel tank engine compartment (40 °C to +80 °C continuous)
• Type 1 Class B = Pressurized [2 bar (0,2 MPa) working pressure] supply and return lines from the fuel tank to the engine compartment (40 °C to +80 °C continuous)
• Type 2 Class A = Pressurized [7 bar (0,7 MPa) working pressure] supply and return lines in the engine compartment (40 °C to la +100 °C continuous)
• Type 2 Class B == Pressurized [working pressure of 2 bar (0,2 MPa)] supply and return lines in the engine compartment (40 °C to la +100 °C continuous)
• Type 3 Class A = Pressurized [7 bar (0,7 MPa) working pressure] supply and return lines in the engine compartment (40 °C to la +100 °C continuous)
• Type 3 Class B = Pressurized [2 bar (0,2 MPa) working pressure] supply and return lines in the engine compartment (40 °C to la +125 °C continuous)
• Type 4 Low pressure [1,2 bar (0,12 MPa) working pressure] fueling, venting and steam treatment (40 °C to +80 °C continuous)

Persons using this part of ISO 19013 should be familiar with normal laboratory practices. This part of ISO 19013 does not purport to address all, if any, security issues associated with its use. Appropriate safety and health
It is the user's responsibility to create applications and ensure compliance with any national regulatory requirements.
