ASTM C 1174 : 1997

1.1 This practice covers steps for the development of methods to aid in the prediction of the long-term behavior of waste package materials and waste forms used in the geologic disposal of high-level nuclear waste.

1.1.1 These steps include problem definition, testing, and modelling.

1.1.2 The predictions will be based on models derived from interpretation of data obtained from tests and appropriate analogs.

1.1.3 These tests may include but are not limited to the following:

1.1.3.1 Attribute tests,

1.1.3.2 Characterization tests,

1.1.3.3 Accelerated tests,

1.1.3.4 Service condition tests,

1.1.3.5 Analog tests, and

1.1.3.6 Confirmation tests.

1.2 The purpose of this practice is to provide information to serve as part of the basis for performance assessment of a geologic repository.

1.3 This practice does not cover other methods of making predictions such as use of peer judgments.

1.4 This standard does not purport to address the safety problems 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.
