Abstract
Standards for non-destructive testing methodologies and methods of fabricating the standards are disclosed herein. The standards include a void-defect coupon that includes a spheroidal void and an elongated void. The spheroidal void has a maximum dimension and a spheroidal void volume. The elongated void had a longitudinal dimension, a maximum transverse dimension, and an elongated void volume. The longitudinal dimension of the elongated void is greater than the maximum dimension of the spheroidal void. The maximum transverse dimension of the elongated void is less than the maximum dimension of the spheroidal void. The methods include forming a first void-defect coupon and forming a second void-defect coupon.
