This Pakistan Standard specifies the requirements of industrial air hose suitable for a maximum design working pressure of 1.0 MPa and a test pressure of 2.5 MPa.
note : Since hoses for heavy duty pneumatic services such as mining, rock drilling, etc., will have more exacting material and test requirements, these are the subject of a separate specification.
