JB/T 10607-2006Code of practice for use of hydraulic fluids (English PDF)

1 Scope

This standard specifies the basic principles for hydraulic system fluids selection, use, storage and discard treatment as well as relevant technical guidance.

This standard is applicable to the hydraulic system for the general industry equipment and mobile machinery hydraulic system.

Fluids in this standard refer to the hydraulic fluids, including hydraulic fluids of mineral oil type and hydraulic fluids of synthetic hydrocarbon type as well as hydraulic fluids of synthetic type and environmentally acceptable hydraulic fluids.

As for the uninflammable hydraulic fluids as the operation specification of fluids, the operation shall be in accordance with the requirements of GB/T 16898.
