ISO 12924:2010
Lubricants, industrial oils and related products (Class L) — Family X (Greases) — Specification
ISO 12924:2010 specifies the requirements of greases used for the lubrication of equipment, components of machines, vehicles, etc. The purpose of ISO 12924:2010 is to provide guidance suppliers and end users of greases and to equipment manufacturers of grease-lubricated equipment.
ISO 12924:2010 is written in a general form so that its application can accommodate various climatic conditions throughout the world. ISO 12924:2010 also stipulates the requirements for the lubricating grease at the time of the delivery.
The classification of family X (greases), which belongs to class L (lubricants, industrial oils and related products), is specified in ISO 6743-9. In this classification, a grease cannot have more than one symbol. This symbol is expected to correspond to the most severe conditions of temperature, water contamination and load in which the grease can be used.
It is intended that ISO 12924:2010 be read in conjunction with ISO 6743-9.
