ISO 8216-2:1986

Overview

ISO 8216-2:1986 - "Petroleum products - Fuels (class F) - Classification - Part 2: Categories of gas turbine fuels for industrial and marine applications" defines a detailed classification system for liquid gas-turbine fuels used in industrial (static) and marine installations. It excludes aircraft fuels and is intended to be read together with ISO 8216‑0 (general rules). The standard covers petroleum-derived fuels that are liquid at atmospheric pressure and normal storage temperatures.

Key topics and requirements

• Scope and exclusion: Applies only to non‑aviation gas turbine fuels for industrial and marine use; only liquids at normal storage conditions are included.
• Classification structure: Fuel designations use a consistent code format beginning with the prefix ISO-F-, followed by a three‑letter category and a numerical grade (e.g., ISO‑F‑DMT 2 or abbreviated F‑DMT 2).
  • First letter: family (D = distillate, R = residual/fuel‑oil).
  • Second letter: service type (S = static/industrial, M = marine).
  • Third letter: application indicator (T = gas turbine).
  • Trailing digit(s) (0–4) provide grade identifiers or observation references; they do not inherently define product property limits.
• Families and sub‑divisions: Distillate families (DST, DMT, etc.) and residual fuel families (RST, RMT, etc.) are used to group fuels of similar refinery origin and typical behavior in turbines.
• Reference to regulatory limits: The standard notes relevant safety/operational constraints (for example, minimum flash‑point considerations for certain DMT categories as identified in maritime safety amendments) and should be used in conjunction with applicable safety regulations.
• Cross‑referencing: Must be read with ISO 8216‑0 for general definitions and rules.

Applications and users

ISO 8216‑2 is practical for:

• Procurement and specifications: Buyers and suppliers specify turbine fuel categories in purchase contracts and fuel delivery documentation.
• Engine manufacturers and OEMs: To determine compatible fuel categories for industrial and marine gas turbines or aero‑derivative engines used in fixed or shipboard installations.
• Fuel testing and quality control labs: For classifying test results against the ISO family and category codes.
• Operators and fleet managers: For fuel selection, storage planning, fuel handling procedures and ensuring compliance with operational safety limits.
• Regulatory and standards professionals: For cross‑referencing fuel classifications with maritime safety and environmental requirements.
