What is ISO 4081 - Cooling systems for internal-combustion engines about?
ISO 4081 is an international standard on rubber hoses and tubing. ISO 4081 specifies the requirements for rubber hoses and tubes in cooling systems for internal-combustion engines.
ISO 4081 specifies the requirements for straight or preformed rubber hoses and tubing for use in pressurized or unpressurized cooling circuits containing 1,2-ethanediol-based coolants in internal-combustion engines for vehicles with an unladen mass (as defined in ISO 1176) of 3,5 t or less.
In addition, this specification may 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 D). In this case, the hose or tubing would not carry any marking showing this ISO specification number but may detail the OEM’s own identification markings as shown on their part drawings.
Who is ISO 4081 - Cooling systems for internal-combustion engines for?
ISO 4081 on Rubber hoses is useful for:
- Chemical industries
- Manufacturers of hoses
- Oil and gas refineries
- Gas stations
- Petroleum industries
Why should you use ISO 4081 - Cooling systems for internal-combustion engines?
Rubber hoses are hollow tube which is useful in transporting oil or water-based liquids from one location to another location.
By using ISO 4081 you can classify the rubber material to be used in hoses according to their operational requirements and size and thickness.
By applying ISO 4081 you can manufacture good quality rubber hoses or tubes that are used in internal - combustion engines.
What’s changed since the last update?
BS ISO 4081:2016 supersedes BS ISO 4081:2010. BS ISO 4081:2016 includes some technical changes with respect to BS ISO 4081:2010. This includes clause 2 has been updated, where ISO 1746 and ISO 4672 have been deleted and replaced by ISO 10619-1 and ISO 10619-2.
