ASTM E 3147 : 2025

1.1This practice covers procedures for evaluating DICONDE compliance of radiographic, ultrasonic, and eddy current examination instruments and systems.

1.2This practice establishes no performance limits for examination systems; if such acceptance criteria are required, these must be specified by the using parties. Where acceptance criteria are implied herein they are for example only and are subject to more or less restrictive limits imposed by customer’s and end user’s controlling documents.

1.3The specific parameters to be evaluated, conditions and frequency of test, and report data required, must also be determined by the user.

1.4This practice may be used for the evaluation of a complete examination system, including search unit, instrument, interconnections, scanner fixtures and connected alarm and auxiliary devices, primarily in cases where such a system is used repetitively without change or substitution. This practice is not intended to be used as a substitute for calibration or standardization of an instrument or system to inspect any given material.

1.5Alternate procedures, such as examples described in this practice, or others, may only be used with customer approval.

1.6It is expected that the customer sets the requirements for the level to which this practice be conformed, including the requirements for which functionality and DICONDE interoperability be incorporated for testing.

1.7Two customer types are targeted for usage: a high-level purchaser wishing to quickly assess results and a low-level systems developer wishing to understand the details about the extent of the results, as discussed in Section 5.

1.8The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.9This 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.

1.10This 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.
