BS EN ISO 3994:2014

This standard BS EN ISO 3994:2014 Plastics hoses. Helical-thermoplastic-reinforced thermoplastics hoses for suction and discharge of aqueous materials. Specification is classified in these ICS categories:

• 23.040.70 Hoses and hose assemblies

This International Standard specifies the requirements for three types of helical-thermoplastic-reinforced thermoplastics hoses for suction and discharge of water, weak aqueous chemical solutions and abrasive solids and slurries, for use in the ambient temperature range from −10 °C to 55 °C.

The three types of hose are for light-, medium- and heavy-duty applications.

The types of hoses covered in this International Standard are not intended for use with flammable or combustible materials, nor with aromatic solvents.

NOTE Hoses of a similar construction for suction and discharge for fire-fighting are specified in ISO 14557.
