Overview

EN ISO 13734:2013 - Natural gas: Organic components used as odorants - Requirements and test methods specifies requirements and laboratory test methods for organic odorants added to natural gas and natural-gas substitutes for public gas supply. The standard covers composition, physical properties, handling, transport, labelling and documentation for odorants used to make normally odourless gas detectable at low concentrations for safety.

Key Topics and Requirements

Odorant performance recommendations - odorants must produce a strong, unpleasant and distinctive smell at very low concentrations; odour character should remain consistent across dilutions and not be easily confused with common smells.

Chemical composition - declared product content of the undiluted odorant shall be at least 95% by mass; for sulfur-containing odorants the mass fraction of sulfides (thioethers) or secondary/tertiary mercaptans should be ≥ 80%.

Preferred chemistries - experience shows organic sulfur compounds (mercaptans/thiols and sulfides) with boiling points below 130 °C typically meet requirements; non-sulfurous odorants (e.g., acrylate-based) require anti-polymerization measures.

Physical property limits - the cloud point of undried odorant shall be below −30 °C to ensure usability at low temperatures; volatility must prevent appreciable condensation in pipelines.

Quality and purity checks - specified tests include determination of composition, cloud point, phase properties, evaporation residue, insoluble matter, solubility in water and visual inspection for solids or suspended matter.

Handling, transport, labelling & documentation - requirements to ensure safe storage, transport and traceability of odorant products and their declared dilution ranges and shelf life.

Applications and Users

Natural gas suppliers and distributors - to specify and procure compliant odorants and ensure safety of distribution systems.

Odorant manufacturers and formulators - to design, test and certify products to meet performance and stability requirements.

Pipeline operators and gas utilities - for quality control, odorization practice and regulatory compliance.

Testing laboratories and certification bodies - to apply the test methods (composition, cloud point, residue, solubility) for acceptance testing.

Regulators and safety engineers - to define national/regional odorization requirements and inspection criteria.

Practical uses:

Product specification for procurement

Routine quality control of odorant batches

Risk mitigation for leak detection effectiveness

Labelling and transport compliance for hazardous goods
