ISO 6743

ISO 6743 is a series of standards published by the International Organization for Standardization (ISO) that covers various aspects of lubricants, industrial oils, and related products. The ISO 6743 series provides a standardized classification and specification system for lubricants used in different industries and applications.

The standards within the ISO 6743 series are organized into several parts, each focusing on specific aspects of lubricants. Some of the key parts of ISO 6743 include:

ISO 6743-1: Lubricants, industrial oils, and related products (class L) – Classification – Part 1: Family X (Hydraulic systems).

ISO 6743-4: Lubricants, industrial oils, and related products (class L) – Classification – Part 4: Family H (Hydraulic systems).

ISO 6743-5: Lubricants, industrial oils, and related products (class L) – Classification – Part 5: Family C (Gear oils).

ISO 6743-6: Lubricants, industrial oils, and related products (class L) – Classification – Part 6: Family D (Compressor oils).

ISO 6743-7: Lubricants, industrial oils, and related products (class L) – Classification – Part 7: Family F (Spindle and hydraulic oils).

ISO 6743-8: Lubricants, industrial oils, and related products (class L) – Classification – Part 8: Family M (Metal working fluids).

And there are additional parts covering various other families and types of lubricants.

These standards provide guidance on the classification, labeling, testing methods, and specifications for lubricants used in specific applications, such as hydraulic systems, gearboxes, compressors, and metalworking operations. Adhering to ISO 6743 standards helps ensure that lubricants meet certain quality and performance requirements, facilitating compatibility, reliability, and efficiency in industrial operations.
