This guide is intended to provide standardized procedures for evaluating ultrasonic search units. It is not intended to define performance and acceptance criteria, but rather to provide data from which such criteria may be established.

These procedures are intended to evaluate the charac...

1.1 This test method covers the nondestructive determination of the thickness of bound pavement layers using Ground Penetrating Radar (GPR).

1.2 This test method may not be suitable for application to pavements which exhibit increased conductivity due to the increas...

1.1 This guide describes measurement procedures for evaluating certain characteristics of ultrasonic search units (also known as "transducers") that are used with ultrasonic examination instrumentation. This guide describes means for obtaining performance data that may be used to define the acous...

This specification covers the requirements for pressure and differential pressure transducers for general applications. Pressure transducers typically consist of a sensing element that is in contact with the process medium and a transduction element that modifies the signal from the sensing eleme...

1.1 This test method covers the measurement of peak braking coefficient of paved surfaces using a standard reference test tire (SRTT) as described in Specification E1136 that represents current technology passenger car radial tires. General test procedures and limitations are presented f...
