F09.10 - Equipment, Facilities and Calibration

SIGNIFICANCE AND USE
5.1 All X-ray systems are subject to changing efficiencies, so a practice for checking the overall operation is needed. This practice will assure the operator of an optimized image when ambient conditions are controlled and the X-ray high voltage generator is adjusted as prescribed.  
5.2 The densities of some tire cord materials are very close to that of the rubber matrix in which they are enclosed, so the resolving capability of an X-ray system is critical to the detection of abnormalities. The rubber-cord pie disk provides a means for optimizing the resolving power in a particular apparatus and for comparing its performance over any period of time.  
5.3 The rubber-cord pie disk can be used to compare the performances of X-ray systems in different laboratories. It can also be used in special cases to optimize system performance for a particular sector or cord-type, as may be required for examining a specific tire.
SCOPE
1.1 This practice describes the construction and use of a rubber-cord pie-shaped standard disk for demonstrating the discernment capability of an X-ray imaging system.  
1.2 This practice is applicable to direct viewing (fluoroscopic) X-ray imaging systems and film, plate or paper (radiographic) X-ray imaging systems that are used for checking the construction consistency of pneumatic tires.  
1.3 The values stated in SI units are to be regarded as the standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 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.

SIGNIFICANCE AND USE
5.1 Calibration is essential in the use of various test platforms and devices to insure that the test results generated by these test devices are accurate, repeatable and meaningful. This standard gives the necessary instructions for the calibration of all of the test devices cited in the Scope.
SCOPE
1.1 This practice gives procedures for the calibration of:
reference load cells
calibration platform systems by using a reference load cell
static calibration of braking/tractive force on locked wheels of tire test trailers, instrumented vehicles, and laboratory tire testing machines by using the calibration platform system as a calibration fixture.  
1.2 The values stated in SI units are to be regarded as standard. The values in parentheses are for information only.

1.4 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.

SIGNIFICANCE AND USE
5.1 The 1.707-m [67.23-in.] diameter laboratory test roadwheel is one of the most extensively employed testing devices for tire durability and endurance testing.  
5.2 This test apparatus operating in the laboratory at controlled surface speeds, loads, and ambient temperatures simulates, to a degree, tire-operating conditions resembling actual service. Because of the roadwheel curvature, the test tire is fatigued more rapidly than a tire operating on a road.  
5.3 The laboratory roadwheel described in this practice is suitable for comparative evaluation of tires under controlled operating and environmental conditions.  
5.4 While the laboratory roadwheel may not reproduce structural fatigue exactly as it occurs in service, the laboratory wheel can be used to produce fatigue under controlled conditions.
SCOPE
1.1 This practice covers the requirements for a 1.707-m [67.23-in.] diameter laboratory roadwheel for durability and endurance testing of tires under controlled operating and environmental conditions.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 7 and Note 1.  
1.4 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.

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 pattern associated with a given size anomaly.  
5.2 The use of straining blocks as calibration devices provides a means for ensuring the continued optimal performance 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 in this practice. When necessary, adjustments, repairs, or modifications shall be made to the S/H system until it is able to observe, in the same image, all anomalies of size within the range of interest contained in the straining blocks.
SCOPE
1.1 This practice describes the construction and use of a calibration device for demonstrating the anomaly detection capability of interferometric laser imaging nondestructive tire inspection system. A common practice within the industry is to refer to these systems as shearographic/holographic (S/H) systems.  
1.2 This standard practice applies to S/H systems that are used for evaluating the structural integrity of pneumatic tires, (for example, presence or absence of anomalies within the tire).  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.2 This test method is intended for use on public highways or closed circuit test courses, or both, that cannot be measured practically by surveying techniques.  
1.3 Use of this test method requires that the surface of the test course to be measured shall be sufficiently smooth to preclude bounce or hop of the fifth wheel, which will affect the accuracy of the measurement. The normal highway surface is adequate for this test method.  
1.4 It is not the intent or scope of this test method to encompass distance measurements of test courses whose surfaces are irregular, broken up, jagged, and so forth, such as rock courses, Belgian block, “rumble” surfaces, and the like. Snow- and ice-covered surfaces also are excluded.

SCOPE
1.1 This test method covers the determination of the accurate length measurement of road courses used for testing all types of pneumatic tires on various associated vehicles.  
1.2 This test method is intended for use on public highways or closed circuit test courses, or both, that cannot be measured practically by surveying techniques.  
1.3 Use of this test method requires that the surface of the test course to be measured shall be sufficiently smooth to preclude bounce or hop of the fifth wheel, which will affect the accuracy of the measurement. The normal highway surface is adequate for this test method.  
1.4 It is not the intent or scope of this test method to encompass distance measurements of test courses whose surfaces are irregular, broken up, jagged, etc., such as rock courses, Belgian block, "rumble" surfaces, etc. Snow- and ice-covered surfaces also are excluded.

SIGNIFICANCE AND USE
The 67.23-in. (1.707-m) diameter laboratory test roadwheel is one of the most extensively employed testing devices for tire durability and endurance testing.
This test apparatus operating in the laboratory at controlled surface speeds, loads, and ambient temperatures simulates, to a degree, tire-operating conditions resembling actual service. Because of the roadwheel curvature, the test tire is fatigued more rapidly than a tire operating on a road.
The laboratory roadwheel described in this practice is suitable for comparative evaluation of tires under controlled operating and environmental conditions.
While the laboratory roadwheel may not reproduce structural fatigue exactly as it occurs in service, the laboratory wheel can be used to produce fatigue under controlled conditions.
SCOPE
1.1 This practice covers the requirements for a 67.23-in. (1.707-m) diameter laboratory roadwheel for durability and endurance testing of tires under controlled operating and environmental conditions.  
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
