5.3.4 All materials with external surfaces will be UV resistant to withstand outdoor
sunlight exposure without fading or material degradation. Reference ASTM
G154 for UV resistance benchmarking
5.3.5 Corrosion resistance: Metal components must withstand 24 hours in a 5%
salt (NaCl) spray (fog) with no major corrosion or visual (including tarnishing
or discoloration) of the components. Reference ASTM B117
5.4 Working Pressure
5.4.1 Valves must function properly at pressures ranging from 10 psi to 100 psi
(static) without leakage from internal components and degradation to
performance
5.4.2 Valves will open and close cleanly with no degradation to performance under
the following pressures: 10 psi, 25 psi, 50psi, 75psi, and 100 psi
5.4.3 Valves will operate at the working pressures while open to atmosphere
5.4.4 Valve will operate at the above conditions restricted with a cap having a 1mm
diameter outlet at working pressures
5.5 Proof Pressure
5.5.1 Timer must withstand a static pressure of 150 psi (150% of max working
pressure) without suffering catastrophic failure. Valves will meet Working
Pressure requirements immediately following Proof Pressure test.
5.6 Burst Pressure
5.6.1 Timer assemblies shall withstand a minimum burst pressure of 700 psi
5.7 Flow Throughput
5.7.1 All valves must meet the following flow requirements to open atmosphere
provided the static head:

Note: Test system must have an unrestricted outlet flow capacity exceeding 15 GPM*
5.8 Full Cycle Fuction Testing
5.8.1 The timer must operate properly through the full range of programs. A
sampling of programs will be tested for ability to turn on and off properly.
5.9 Product Life
5.9.1 Each valve to reach a minimum of 1,200 cycles by means of actuation at 100
PSI static with a water supply temperature range of 40°F to 80°F
5.9.2 After 1,200 cycles, units will still meet Environmental Requirements and
Standard Performance Requirement for Working Pressure.
