Plastics hoses - Helical-thermoplastic-reinforced thermoplastics hoses for suction and discharge of aqueous materials - Specification

ISO 3994:2007 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 the 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, Fire-fighting hoses — Rubber and plastics suction hoses and hose assemblies.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
