What is BS EN 60332-2-1 - Vertical flame propagation for a single small insulated wire or cable about?
BS EN 60332-2-1 is a European standard and a part of the BS EN 60332 series that discusses the test for vertical flame propagation for a single small insulated wire or cable for electrical and optical fibre cable under fire conditions.
BS EN 60332-2-1 specifies the test apparatus for testing the resistance to vertical flame propagation for a single small vertical electrical insulated conductor or cable, or optical fibre cable, under fire conditions.
Who is BS EN 60332-2-1 - Vertical flame propagation for a single small insulated wire or cable for?
BS EN 60332-2-1 on vertical flame propagation for a single small insulated wire or cable applies to:
- Manufacturer of fibre optic cables
- Manufacturers of electrical insulated conductor or cable
- Quality testing personnel
- Electrical engineers
Why should you use BS EN 60332-2-1 - Vertical flame propagation for a single small insulated wire or cable?
The purpose of the vertical flame test is to verify the behaviour of the cable installed individually in the most unfavourable position, namely in the vertical position, to prevent the propagation of flames that may be transmitted from an external source. The insulation burns, but the flame must not propagate for more than a specified distance from the point to which the individual cable is applied. A fibre-optic cable contains anywhere from a few to hundreds of optical fibres within a plastic casing.
In this regard, BS EN 60332-2-1 provides you with the test apparatus which includes: Metallic screen, ignition source and a suitable chamber that helps in the tests on electric and optical fibre cables under fire conditions.
With BS EN 60332-2-1, you can gain detailed instruction that will be valuable throughout the manufacturing process of electric and optical fibre cables.
