Campbell Test Reports

Abbreviated Reports and Results
Campbell engineering has conducted nearly 1,000 hydrostatic tests. The following are results from several popular products. Please contact
our customer support team to receive test reports on other Campbell products.
The Safety Factor
The RMA requires that hose working pressures include a safety factor commensurate with their intended application. Most hoses are required
to meet a 4x safety factor, except the following: Water hose rated under 150 PSI requires a 3x safety factor; Steam hose requires a 10x safety
factor; and Hose conveying gas in a liquid state requires a 5x safety factor. (For example: a 150 PSI rated air hose has a 4x safety factor and
must be successfully tested to a minimum of 600 PSI.)
Campbell’s fitting and coupling pressure ratings match the RMA safety factor requirements with most hoses. Due to the wide variety of
industrial hoses, as well as variations in design, construction, and material, we cannot guarantee that our pressure ratings meet the safety
factor requirement with every hose.
If you have any questions about pressure ratings, please contact Campbell Fittings.
