Overview

EN ISO 1401:2016 - "Rubber hoses for agricultural spraying" is a CEN-endorsed adoption of ISO 1401:2016 that specifies design, material and test requirements for flexible rubber hoses used for pressure spraying of agricultural chemicals and fertilizers. The standard covers hoses intended to operate in a temperature range of –10 °C to +60 °C and defines three performance types (A, B, C) by maximum working pressure.

Key topics and technical requirements

• Classification
  • Type A: max working pressure 1.0 MPa (10 bar)
  • Type B: max working pressure 4.0 MPa (40 bar)
  • Type C: max working pressure 6.0 MPa (60 bar)
• Construction and materials
  • Inner synthetic rubber lining, textile-fibre reinforcement, and natural or synthetic rubber cover.
• Dimensions & tolerances
  • Nominal bores range from 6.3 mm to 25 mm with defined inside-diameter tolerances (e.g., 6.3 mm ±0.75 mm; 25 mm ±1.25 mm).
  • Length tolerances as per ISO 1307.
• Minimum thickness
  • Types A/B: lining ≥ 1.6 mm; cover ≥ 1.0 mm.
  • Type C: lining ≥ 2.0 mm; cover ≥ 1.6 mm.
• Mechanical properties
  • Tensile strength (ISO 37): lining ≥ 7.0 MPa, elongation ≥ 200%; cover ≥ 7.0 MPa, elongation ≥ 250%.
• Chemical and ageing resistance
  • Immersion testing (ISO 1817) in the actual service fluid: volume increase, tensile and elongation limits after 72 h immersion (maximum volume increase 55%; tensile strength reduction max 50%; elongation reduction max 40%).
  • Accelerated ageing (ISO 188): samples aged 72 h at 100 °C; post-ageing property limits are specified in the standard.
• Finished-hose tests
  • Hydrostatic testing, bending/flexibility (ISO 10619-1), adhesion (ISO 8033), ozone resistance (ISO 7326), dimensional change and other routine/type tests.
• Quality and compliance
  • Clauses on frequency of testing, type tests, production acceptance tests, marking and test reports/certificates.

Applications and users

• Primary use: pressure hoses for agricultural sprayers used to apply pesticides, herbicides and liquid fertilizers.
• Who uses the standard:
  • Hose manufacturers and compounders specifying construction and performance.
  • Agricultural equipment OEMs and sprayer designers specifying hose assemblies.
  • Test laboratories performing compliance and type testing.
  • Procurement teams and spec writers requiring documented performance for safety and durability.
  • Farmers and contractors seeking compatible, certified replacement hoses.
