Plastics hoses - Helical-thermoplastic-reinforced thermoplastics hoses for suction and discharge of aqueous materials - Specification
N EN ISO 3994
Annotation
This International Standard specifies the requirements for three types of helical-thermoplasticreinforced 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
