Description / Abstract:
Purpose: This Aerospace Standard establishes an
identification system and provides design and tolerance information
in describing two series of image quality indicators currently used
in radiography of aerospace components, especially in electronic
component evaluation and radiographic film and paper
classification.
Classification: Individual image quality indicators
(IQIs) are classified by use of this standard number, followed by
appropriate codes, as shown in Table I. Synopsis of the
classification system is:
AS 1613-A-XX IQI shown in Fig. 1, with six tungsten wires
AS 1613-B-XX IQI shown in Fig. 2, with six tungsten wires and
six lead beads.
