Overview

EN ISO 8028:2024 - "Rubber and/or plastics hoses and hose assemblies for airless paint spraying - Specification" - defines material, construction, performance and marking requirements for hoses and hose assemblies used in high‑pressure airless paint spraying. Published by CEN/ISO in 2024, it replaces the 2018 edition and applies to four hose types differentiated by maximum working pressure and operating temperature. This standard is essential for manufacturers, test laboratories, specifiers and purchasers of airless spray equipment.

Key topics and technical requirements

• Types and ratings
  • Type A: max working pressure 20 MPa (200 bar); temperature range −20 °C to +50 °C
  • Type B: max working pressure 36 MPa (360 bar); temperature range −20 °C to +50 °C
  • Type C: 20 MPa; −20 °C to +80 °C
  • Type D: 36 MPa; −20 °C to +80 °C
• Construction and materials
  • Hose consists of a smooth seamless rubber or plastics lining, wire or textile reinforcement, and a rubber or plastics cover. Combinations (plastic tube with rubber cover) are permitted.
  • An electrically conductive element (conductive compound or bonding wires) must be incorporated and connected to fittings to meet electrical‑continuity requirements throughout service life. Hoses are marked Ω (conductive compounds) or M (bonding wires).
  • Permanent, electrically conducting couplings are required and shall only be used if they meet test criteria.
• Dimensional control
  • Inside diameters and tolerances are specified (see Table 1 in the standard) to ensure compatibility with fittings and spray equipment.
• Performance testing
  • Adhesion between lining/lamination and cover/lamination measured per ISO 8033: minimum 0.8 kN/m (ID ≤ 20 mm) and 0.9 kN/m (ID > 20 mm); three samples per production run.
  • Hydrostatic testing per ISO 1402 and hydraulic‑pressure impulse testing per ISO 6803.
  • Electrical resistance and conductivity per ISO 8031 to ensure safe dissipation of static charge.
  • UV resistance (plastics cover) per ISO 30013: no cracking; ozone resistance (rubber cover) referenced to applicable test methods.
• Marking, packaging and test reporting
  • Marking requirements, frequency of testing and packaging/storage recommendations are specified.

Applications and users

• Intended for airless paint spraying systems handling solvent‑based coatings in construction, industrial coatings, automotive, marine and maintenance sectors.
• Primary users: hose and assembly manufacturers, quality and compliance engineers, equipment OEMs, testing laboratories, procurement/specification teams and site safety personnel who require certified high‑pressure hoses for solvent‑based spray applications.
