Petroleum products and lubricants - Determination of cone penetration of lubricating greases and petrolatum

ISO 2137:2007 specifies several methods for the empirical estimation of the consistency of lubricating greases and petrolatum by measuring the penetration of a standardized cone. Four procedures are specified for determining the consistency of lubricating greases by measuring the penetration of a full-scale cone for unworked, worked, prolonged worked and block penetrations for penetrations of up to 500 units. ISO 2137:2007 specifies methods for determining the consistency of lubricating greases when only small samples are available, by the use of cones a half-scale or quarter-scale for the listed methods, applicable to greases having penetrations of 175 units to 385 units using the full-scale cone.

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.
