ISO 1823:2015 PDF

Overview

ISO 1823:2015 - Rubber hose and hose assemblies for oil suction and discharge service specifies requirements for rubber hoses and hose assemblies used to convey petroleum (including crude oil and liquid petroleum products) for suction and discharge operations. The standard covers four hose types (rough bore, armoured rough bore, smooth bore, and light weight) across three classes based on aromatic content, and applies to nominal sizes 50 to 500 and a temperature range of −20 °C to 80 °C. It explicitly excludes liquefied petroleum gas (LPG) and natural gas.

Key topics and technical requirements

• Classification and designation
  • Types: Type R (rough bore, stiff, electrically continuous), Type A (armoured, electrically continuous), Type S (smooth bore, flexible, electrically continuous or discontinuous), Type L (lightweight, discharge-only, electrically continuous or discontinuous).
  • Classes: Class 25 (suitable for oils/gasoline below 25% aromatics), Class 50 (up to and including 50% aromatics), Class 100 (for higher aromatic-content products).
• Materials and construction
  • Lining, reinforcing plies, wire helices (internal and armouring), and cover materials are specified to ensure compatibility and durability.
• Electrical continuity
  • Requirements for electrically bonded vs electrically discontinuous hose assemblies - important for static-charge control. Warning: electrically discontinuous hoses require careful consideration and earth continuity measures during transfers.
• End connections and attachment methods
  • Specifications for nipples, flanges and methods for securing couplings to hoses.
• Dimensions, tolerances and physical properties
  • Nominal size range, length tolerances, rubber compound properties, abrasion and ozone resistance.
• Testing and conformity
  • Type tests, hydrostatic tests, wet adhesion tests, test frequency and routine/production testing requirements; test reports and marking requirements.
• Informative annexes
  • Purchaser information, packaging and transport recommendations, expected masses and normative test procedures.

Practical applications

• Transfer of crude oil and liquid petroleum products between tankers, barges and shore facilities
• Dock and bunkering hose services where robustness, flexibility, or lightweight handling is required
• Marine and shore-based petroleum transfer operations (excluding LPG and natural gas)

Who should use ISO 1823:2015

• Hose and coupling manufacturers and designers
• Ship operators, terminal and port operators, and bunkering services
• Procurement, quality, and maintenance engineers specifying oil transfer hose assemblies
• Safety and compliance officers ensuring transfer operations meet industry standards
