ASTM F1364-03(2022)

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the
Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Designation: F1364 − 03 (Reapproved 2022)
Standard Practice for
Use of a Calibration Device to Demonstrate the Inspection
Capability of an Interferometric Laser Imaging
Nondestructive Tire Inspection System
This standard is issued under the fixed designation F1364; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.

5. Significance and Use
5.1 All S/H systems change with time and use. Therefore, a
calibration procedure for evaluating the operation of an S/H
system is desirable. This calibration procedure provides a
method of obtaining an optimized interferometric image pat-
tern associated with a given size anomaly.
5.2 The use of straining blocks as calibration devices
provides a means for ensuring the continued optimal perfor-
mance of the S/H system. Straining blocks can also be used to
compare performance of S/H systems in different facilities.
5.3 At not greater than a three (3) month interval the S/H
system shall be calibrated following the procedures described
