ISO 1403:2019 PDF

Overview

ISO 1403:2019 establishes the requirements and specifications for three types of general-purpose textile-reinforced rubber water hoses. This international standard is issued by ISO to ensure uniformity in hose quality and performance for non-potable water applications. The hoses covered by this standard are designed for operation within a temperature range of −25 °C to +70 °C and can withstand maximum working pressures of up to 2.5 MPa (25 bar). These hoses are not intended for drinking water, washing-machine inlets, firefighting, specialized agricultural machines, or as collapsible water hoses. However, they may be used with water-antifreeze solutions.

Key Topics

• Types and Classification:

  • Type 1: Low pressure (up to 0.6 MPa / 6 bar)
  • Type 2: Medium pressure (up to 1.0 MPa / 10 bar)
  • Type 3: High pressure (up to 2.5 MPa / 25 bar)

• Materials and Construction:

  • Textile-reinforced rubber structure with a uniform inner lining and protective cover.
  • Reinforcement may use natural or synthetic textiles.
  • Cover finish options include smooth, fluted, or fabric-marked surfaces.

• Physical and Mechanical Properties:

  • Durability in a wide temperature range (−25 °C to +70 °C).
  • Compliance with dimensional tolerances and concentricity.
  • Minimum thickness requirements for lining and cover.
  • Mechanical testing for properties such as tensile strength, elongation, burst pressure, flexibility, ozone resistance, and adhesion between components.

• Identification and Marking:

  • Continuous, durable marking including manufacturer, ISO standard reference, hose type, internal diameter, maximum working pressure, and date code.

Applications

• Industrial Water Conveyance:
  • Suitable for general distribution and transfer of non-potable water in industrial settings.
• Construction:
  • Used for water delivery on construction sites where robust hoses with reliable performance are critical.
• Irrigation and Landscaping:
  • Supports non-potable water transfer for turf, garden, and landscape maintenance.
• Maintenance and Cleaning:
  • Applied in cleaning operations where water is required, but not for potable uses.

Note: These hoses are not intended for drinking water supply, firefighting, washing machine inlets, collapsible applications, or use with certain agricultural equipment.

Practical Value

The ISO 1403:2019 standard supports manufacturers, users, and specifiers in:

• Selecting appropriate textile-reinforced rubber hoses for general-purpose water applications.
• Ensuring supply chain compatibility and safety compliance.
• Verifying hose quality and durability through standardized testing.
• Improving operational efficiency and reducing risk by using hoses with reliable and validated characteristics.

Implementing ISO 1403:2019 in your operations helps ensure consistent product quality, fit for purpose water conveyance, and alignment with international best practices in hose manufacturing and selection.
