Mounting blocks are used when it is impractical to place the I.Q.I. directly on the object being radiographed. Most codes specify that a mounting block of the same material and thickness be placed, with the I.Q.I., adjacent to the part in such a manner that it will show clearly on the radiograph. Standard mounting blocks are supplied in sizes corresponding with IQI sizes.
General Dimensions :
· Sizes up to 2 1/2″, 1″ X 2 1/4″
· Sizes over 2 1/2″, 1 1/4″ X 3″
These dimensions allow at least 1/8″ clearance on three sides of the IQI.
