<strong>Performance</strong> Considerations<br />
40<br />
Related to Design Pressure<br />
<strong>Performance</strong> Grade = Design Pressure<br />
Structural Test Pressure = 1.5 Design Pressure<br />
Water Resistance Test Pressure = 0.15 Design Pressure for R, LC, CW<br />
0.20 Design Pressure for AW<br />
This, then, is the key to underst<strong>and</strong>ing product performance<br />
requirements <strong>and</strong> testing – that the major structurally-related<br />
aspects are all related directly to the design pressure.
