1.1 This guide covers recommended formats for the recording of fatigue and fracture test data for inclusion in computerized material property databases. From this information, the database designer should be able to construct the data dictionary preparatory to developing a database schema. Not covered within the scope of this guide are guidelines for the identification of the materials themselves, or descriptions of the materials, or both. Those guidelines are covered in separate standards, such as Guides E1338 and E1339.

1.2 The recommended format specified in this guide is suggested for use in recording data in a database, that is different from contractual reporting of actual test results for a specific lot of material. The latter type of information is specified in materials specifications shown in business transactions and is subject to agreement between supplier and purchaser.

1.3 This guide is specific to plane-strain fracture toughness test data based on Test Method E399, fatigue crack growth rate test data based on Test Method E647, and strain-controlled fatigue testing based on Practice E606.

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 and health practices and determine the applicability of regulatory limitations prior to use.
