Testing Equipment Requirements. Maintain the equipment in good working condition and submit a written certification to the Administration stating when the testing equipment was last calibrated or inspected by an Administration approved testing agency. Ensure that the equipment is calibrated at the frequency required for that type of equipment according to the test method and AASHTO R18. If any testing equipment or accessories are stolen, become defective, or for any other reason do not function as intended, replace with an equal or better unit at no additional cost to the Administration within eight hours after notification. Sampling Devices and Testing Equipment with Accessories. The following is a general list for sampling devices and testing equipment to be furnished by the Contractor for the specified testing.

114.03 Construction
Establish truck staging areas for all vehicles waiting to load or unload materials at the job site. Subject to review and approval by the Administration, locate staging areas where emissions will have the least impact on sensitive areas and the public. Sensitive areas include, but are not limited to, hospitals, schools, residences, motels, hotels, daycare facilities, and elderly housing and convalescent facilities. All sources of emissions shall be located as far away as possible from fresh air intakes, air conditioners, and windows. Idling of all mobile construction equipment, including delivery trucks, shall be limited to five minutes except under any of the following circumstances:
a.When forced to remain motionless because of traffic conditions or mechanical difficulties over which the operator has no control.
b.When necessary to operate defrosting, heating, or cooling equipment to ensure the safety or health of the driver or passenger.
c.When necessary to operate auxiliary equipment that is located in or on the mobile source to accomplish the intended use of the mobile source.
d.To attain the recommended operating temperature.
e.When the outdoor temperature is below 32 F. 2025 STANDARD SPECIFICATIONS FOR CONSTRUCTION AND MATERIALS
