Specifies dimensional and performance requirements for 14 classes of hydraulic hose having burst pressures up to 345 MPa and operating temperatures from -55°C to 205°C. Flexibility, visual examination and marking requirements are also covered.
Scope
This Standard specifies 14 classes for hydraulic hose having burst pressures up to 345 MPa and operating temperatures from -55°C to 205°C when used under normal operating conditions.
The Standard covers hose manufactured from elastomeric materials, reinforced with braided or spirally wound steel wire, or with braided textile or a combination of these materials.
The Standard sets out dimensional and performance requirements, together with the methods for testing the performance requirements stated.
The Standard does not cover requirements for hydraulic hose for use in underground mines.
NOTE: Operating temperatures and pressures in excess of that specified for the appropriate class may materially reduce the life of the hose.
