ISO 3994:2014 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.
