Petroleum products - Inhibited mineral oils - Determination of oxidation characteristics

Specifies a method for evaluating oxidation stability of inhibited steam-turbine oils in the presence of oxygen, water, and metallic copper and iron at an elevated temperature. The method is also used for testing other oils such as hydraulic oils and circulating oils having a relative density less than that of water and containing rust and oxidation inhibitors. This method is used for specification purposes and is considered of value in evaluating the oxidation stability of lubricants, especially those that are prone to water contamination.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:

  • mandatory clauses to satisfy,
  • non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document "ISO/IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents" as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
