This document specifies requirements for rubber hoses and tubing for use in the various air and vacuum systems found on internal combustion engines. This document does not cover hoses used for direct power-brake actuation in trucks and trailers, nor for air intakes and ducting within the passenger compartment. The highest-temperature hoses are generally used for turbocharger applications. All hoses and tubing remain serviceable down to −40 °C. NOTE Although the term vacuum is generally used, in reality the application is one of reduced air pressure used for the purposes of actuation or monitoring of the various engine-system components. The air carried by the tubing or hoses can be clean and free of contaminants but can also contain oil, fuel and their vapours as contamination, due to the particular installation and application.

This document specifies the requirements for rubber hoses and hose assemblies used for low-pressure application of circulating gaseous Refrigerant 1234yf (tetrafluoropropene) (hereinafter referred to as R1234yf) in the air-conditioning systems of automobiles. The hoses and hose assemblies are designed in such a way as to reduce vibration transmission between the engine room and the cabin. The operational temperature range is −40 °C to +80 °C. Due to the critical relationship between the hose and coupling for this application, a requirement that the coupling to be used in service be used for testing is laid down.

This document specifies the requirements and test methods for verification for hose assemblies with vapour recovery for delivery systems on petrol filling stations.
The hose assemblies with vapour recovery for delivery systems on petrol filling stations need to be capable of withstanding anticipated mechanical, thermal and chemical stressing and be resistant to the combustible liquids used in these applications as well as their vapour and vapour air mixtures. It is imperative that the assemblies be constructed in such a way that actions during normal operation cannot give rise to dangerous electrostatic charges nor that there will be any reduction in the performance of the vapour recovery.
The assemblies are intended for use at ambient temperatures between –30 °C and +55 °C for normal temperature class and –40 °C and +55 °C for low temperature class at a working pressure ≤ 16 bar .
Hoses can be constructed from rubber or thermoplastic elastomer (TPE) and this document specifies the requirements for three types of hoses in two grades and two classes of hose assemblies for measured fuel dispensing systems, including oxygenated fuels (≤15 % oxygenated compounds) with internal vapour recovery tubing or hose.
NOTE   This document is not applicable to multi chamber fuel dispensing hoses.
As part of the certification of a new dispenser, testing of fuel samples in accordance with EN 228 are carried out at least eight weeks after the first use of the equipment to avoid unrepresentative sulphur content results.

This document specifies requirements for three types of textile-reinforced thermoplastics hoses and hose assemblies of nominal size from 3,2 to 25. Each type is divided into two classes dependent on electrical conductivity requirements. They are suitable for use with: — oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743‑4 at temperatures ranging from −40 °C to +93 °C; — water-based fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743‑4 at temperatures ranging from 0 °C to +60 °C — water at temperatures ranging from 0 °C to +60 °C. This document does not include any requirements for end fittings. It is limited to the performance of hoses and hose assemblies. NOTE It is the responsibility of the user, in consultation with the hose manufacturer, to establish the compatibility of the hose with the fluid to be used.

This document specifies the requirements for rubber tubing and hoses used in diesel fuel circuits for internal combustion engines. The diesel fuels covered include "bio-diesels" which consist of the methyl ester of rape seed oil at levels up to 20 % by volume in conventional diesel fuels. This document can also be applied as a classification system to enable original equipment manufacturers (OEMs) to detail a "line call-out" of tests for specific applications where these are not covered by the main types specified (see example in Annex E). In this case, the hose or tubing would not carry any marking showing the number of this document but can detail the OEM's own identification markings as shown on their part drawings.

ISO 21012:2018 specifies design, construction, type and production testing, and marking requirements for non-insulated cryogenic flexible hoses used for the transfer of cryogenic fluids within the following range of operating conditions:
-      working temperature: from −270 °C to +65 °C;
-      nominal size (DN): from 10 to 100.
End fittings for mounting of any couplings are within the scope of this document, but the couplings are subject to other standards.
ISO 21012:2018 is intended that the hose be designed and tested to satisfy the generally accepted rated pressure i.e. at least PR 40. Hoses may be then selected with a PR equal to or greater than the maximum allowable pressure (PS) of the equipment to which it is to be used.
