Preheating of liquid fuel oils according to this standard can be necessary for transport, storage, and combustion.
The mixing with fuel oils from other raw materials should be avoided.
This standard does not cover marine fuel applications.

This European Standard specifies the requirements, acceptance tolerances and chemical and physical test procedures for lead oxides, considering litharges (powder or granulated), battery oxides (Barton or Mill) and crystal red lead. WARNING: Lead and lead compounds are toxic by inhalation and/or ingestion.

This European Standard is applicable to ammonia solution used for treatment of water intended for human consumption. It describes the characteristics of ammonia solution and specifies the requirements and the corresponding test methods for ammonia solution. It gives information on its use in water treatment.

The method is based on titration of dissolved test portion with a standard volumetric solution of sodium hydroxide in the presence of mannitol or sorbitol, using phenolphthalein as indicator. Water, free from carbon dioxide, shall be used in the test.
