What is BS EN 1765 - Rubber hose assemblies about?
BS EN 1765 is an international standard used for rubber hose assemblies that specifies the materials and requirements for assembling rubber hoses. These hoses are useful in transporting oil.
BS EN 1765 specifies the characteristics of four types of oil suction and discharge hose assemblies used for the conveyance of petroleum, including crude oils and other liquid petroleum products containing a maximum aromatics content of 50 % (v/v). Hose assemblies to BS EN 1765 can be used in the temperature range −20 °C to 82 °C.
The hoses specified are in the size range of nominal bore 50 to 500 and maybe smoothbore, rough bore or armoured rough bore. Hoses for use with petroleum products having an aromatic content greater than 50 % (v/v) are outside the scope of BS EN 1765 but the requirements may be used as a basis for such hoses on request to the manufacturer.
Note: BS EN 1765 is not suitable for liquified petroleum gas and natural gas.
Who is BS EN 1765 - Rubber hose assemblies for?
BS EN 1765 on Rubber hose assemblies is useful for:
- Manufacturers of hoses
- Chemical industries
- Oil refineries
Why should you use BS EN 1765 - Rubber hose assemblies?
Hoses are useful in transporting oil or water-based liquids from one location to another location.
Using BS EN 1765 you can classify hoses according to the operational use of the end-users. The dimensions mentioned in BS EN 1765 helps in designing and constructing these rubber hoses according to their operation usage. This is useful in determining the physical properties of rubber hoses assemblies. The materials specified for rubber hoses are useful in constructing, manufacturing and assembling these hoses.
By using BS EN 1765, you can ensure the sustainability of these rubber hoses in different climatic conditions. This result in manufacturing and assembling good quality rubber hoses which helps in carrying and suctioning oil.
What’s changed since the last update?
BS EN 1765:2016 supersedes BS EN 1765:2004. BS EN 1765:2016 includes some technical changes with respect to BS EN 1765:2004. These include:
- Clause 2: the normative references have been updated
- Subclause 4.2: hose assemblies type S and L were subdivided into two grades Grade M (electrically bonded) and Grad Ω (electrically conductive)
- Subclause 5.2.3.2: one type of hose assembly assembled with hose nipples in accordance to EN 14420-2 and swaged or crimped ferrules has been added
- Table 4: for the electrical properties (continuity) the maximum electrical resistance 106 per assembly for grade Ω was added
- Clause 12: the requirements for marking have been amended
