C.3.2 The SPIdER shall be capable of performing the tests identified below, with each of the two data measuring fixtures incorporated into the upgraded SPIdER having a required capacity to accept weights of up to 80,000 pounds per axle of the vehicles subject to test and a desired capacity of up to 100,000 pounds per axle.

C.3.3 Upon completion of the enhancements provided for in this PWS, the SPIdER shall have the capacity to provide all suspension parameter input to satisfy inputs required for Mobility analysis for Army vehicle platforms.

C.3.4 The SPIdER shall be capable to perform tandem suspension measurements.

C.4 Design Criteria

C.4.1.8 Provide a traceable calibration acceptable to ISO17025 certification. (CLIN 0001 – BASE) (Task 1) C.4.1.9 Thoroughly document the analysis of the measuring capabilities of the test rig. Including all inputs to the system including empirically developed constants. (CLIN 1001 – OPTION) (Task 2) C.4.1.10 Document an uncertainty budget defining the input and calibration parameters that must be stayed within for these possible sources of error. (CLIN 1002 – OPTION) (Task 3) C.4.1.11 Contractor shall provide a final report that will quantify that the SPIdER system is compliant with the ISO 17025 regulation. (CDRL A008) C.4.2 The SPIdER with traceable calibration acceptable to ISO17025 certification (also referred to as the SPIdER V) shall encompass all necessary data analysis software modifications to properly process recorded data and calculate results for vehicles with axle loads of up to 100,000 lb.

C.4.3 The SPIdER V’s measurement system shall be capable of encompassing an accuracy of <1% error and shall yield results of <3% on vehicle axle loads up to 100,000 lb.

C.4.4 RESERVED

C.4.5 The contractor shall provide all software maintenance support updates required for the SPIdER V for one year.

C.5 Safety

C.5.1 The SPIdER V shall be protected by interlocks such that proper sequencing of power-up or power-down is ensured and that abnormal conditions inhibit the application of hydraulic or pneumatic power to the modified SPIdER apparatus. At a minimum, the Contractor shall provide interlocks to stop or prevent system operation whenever any-one or any combination of the following conditions prevails:

a. Hydraulic or pneumatic pressure too high or too low

b. Actuator stroke limits exceeded

c. Motion limits reached

d. Excessive position error

e. Emergency stop switch activated

f. Power supply voltage too low

g. Amplifier failure

h. Interlock circuits open

C.6 Test Plan

C.6.1 The Contractor shall develop a test plan to prove that the SPIdER V meets the requirements outlined in Section C.3. The Government will review the draft test plan and provide comments within ten days of receipt of the draft test plan (CDRL A001).

C.6.2 The acceptance test shall be performed at TACOM’s facility when the system is installed and operating. (CDRL A001) C.6.3 the Government reserves the right to observe all testing. The Contractor shall provide the COR with a detailed test schedule at least two (2) weeks prior to the start of testing.
