5.2 Flat bottom holes standards Flat bottom holes in the master test blocks shall be used to calibrate standard test blocks. The master test blocks shall have FBH at different metal paths to suit the product range to be inspected. It shall be ensured however that there is sufficient number with a minimum of three different metal paths to accurately produce the required distance/amplitude curve (see 5.4.2.2). 5.3 Manufacture 5.3.1 Material procurement Material for each set of master test blocks shall be obtained from the same cast, forging and heat treatment batch. For longitudinal waves when checking anisotropic materials, the FBH shall be drilled perpendicular to the grain flow, if possible, but always perpendicular to the surface. Ultrasonic tests shall be carried out on each test block to ensure:  freedom from defects greater than or equal to − 12 dB below the DAC (see EN 4050-1);  consistent grass level across each test block and between master test blocks in the vicinity of the FBH. Maximum variation ± 3 dB;  consistent attenuation across each test block and between master test blocks not to exceed 0,1 dB/cm variation. SIST EN 4050-3:2014
