• To enable confident Product Sign-Off for safety critical road vehicle springs made from novel composite material

• Survey the most demanding service environments experienced by steel springs in the market segment
• Road load data collection, on-road and off-road for limit condition duty cycles
• Data analysis to generate proving ground feature combinations representing an 80:1 mileage acceleration ratio, then definition of a 2,000 mile multi-cycle proving ground sign-off test.

• Test regime approved and adopted by subsequent vehicle customers
• Data acquisition applied to laboratory servo hydraulic multi axis test rigs for simultaneous component testing
• Safety critical components validated for road application
• Service duty represented while avoiding unrepresentative torture tests which can cause costly over-design
