Resumen:
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.
