STANDARD SPECIFICATIONS FOR BUILDING WORKS (2005 Edition)
2.6 Maintained Load Test
A loading test in which each increment or decrement of load is held constant either for a
defined period of time or until the rate of settlement or rebound falls to a specified value.
2.7 Constant Rate of Penetration Test (CRP)
A loading test in which the pile is made to penetrate the soil from its position at a constant
speed while the force applied at the top of the pile to maintain the rate of penetration is
continuously measured, until the force versus penetration relationship obtained does not
represent an equilibrium condition between load and settlement.
