Overview

EN 12876:2015 is the CEN European Standard that defines requirements for oxygen used in the treatment of water intended for human consumption. Published in 2015 (approved 20 Dec 2014) and prepared by CEN/TC 164 “Water supply”, the standard describes identification, physical and chemical properties, purity criteria, test methods, labelling, transportation and storage information, and guidance on safe use of oxygen in drinking-water applications.

Key topics and technical requirements

• Scope and identification
  • Chemical name: Oxygen (O2), relative molecular mass 32.00, CAS 7782‑44‑7, EINECS 231‑956‑9.
  • Commercial forms: gas or cryogenic liquid.
• Physical and chemical properties (examples provided in the standard)
  • Liquid density: 1.141 g/ml at −183 °C; gas density 1.337 g/dm3 at 15 °C and 101.3 kPa.
  • Solubility in pure water: 61 mg/L at 5 °C, 45 mg/L at 15 °C, 36 mg/L at 25 °C.
  • Boiling point: −182.97 °C; oxygen is an oxidizing agent and supports combustion.
• Purity criteria
  • Minimum purity requirements and limits for common impurities and by‑products are specified. The standard requires suppliers to notify users of other impurities arising from raw materials or production processes.
• Test methods and sampling
  • Sampling and analytical methods are defined for main product composition and impurities (including a Methane Index method in Annex C).
• Labelling, transport and storage
  • Instructions for cylinder/container marking and storage safety, including references to gas cylinder identification standards and safety labelling requirements.
• Safety and monitoring
  • Annexes cover safe handling, emergency procedures, monitoring methods (e.g., chromatographic methods, oxymeters), and fire/explosion considerations for oxygen‑rich atmospheres.

Applications and who uses it

EN 12876:2015 is used by:

• Water utilities and drinking‑water treatment plants assessing chemical feeds.
• Industrial gas producers and suppliers specifying oxygen quality for potable‑water use.
• Analytical laboratories performing purity and impurity testing.
• Regulators, procurement teams and safety officers ensuring compliance with national rules for chemicals in drinking water.
• Consultants and designers specifying application doses, injection methods and monitoring for oxygen dosing processes.

Related standards

• EN 1089‑3 (Transportable gas cylinders - gas cylinder identification) is normatively referenced.
• Prepared by CEN/TC 164 (Water supply); users should also check relevant national drinking‑water regulations for acceptance and permitted uses.
